96-558: The Sendai Mediatheque held its official opening in January 2001. Ito also refers to Mies' Barcelona Pavilion and Le Corbusier ’s Dom-ino house as precedents for his work, and indeed, the Mediatheque appears to mix concepts from the two projects, combining le Corbusier’s play with slab and column structure, with Mies “fluid” spatial effects achieved through combined transparency and reflectivity of materials. The Sendai Mediatheque

192-446: A completely new concept of architecture. ...The complex includes a Mediatheque, an art gallery, a library, an information service center for people with visual and hearing impairments and a visual image media center. During the open competition and subsequent phase of basic designing, our primary effort was on demolishing the archetypal ideas of an art museum or library to reconstruct a new idea of architecture called "mediatheque" utilizing

288-571: A depth of less than 70 km (43 mi) are classified as "shallow-focus" earthquakes, while those with a focal depth between 70 and 300 km (43 and 186 mi) are commonly termed "mid-focus" or "intermediate-depth" earthquakes. In subduction zones, where older and colder oceanic crust descends beneath another tectonic plate, deep-focus earthquakes may occur at much greater depths (ranging from 300 to 700 km (190 to 430 mi)). These seismically active areas of subduction are known as Wadati–Benioff zones . Deep-focus earthquakes occur at

384-488: A depth where the subducted lithosphere should no longer be brittle, due to the high temperature and pressure. A possible mechanism for the generation of deep-focus earthquakes is faulting caused by olivine undergoing a phase transition into a spinel structure. Earthquakes often occur in volcanic regions and are caused there, both by tectonic faults and the movement of magma in volcanoes . Such earthquakes can serve as an early warning of volcanic eruptions, as during

480-475: A few exceptions to this: Supershear earthquake ruptures are known to have propagated at speeds greater than the S wave velocity. These have so far all been observed during large strike-slip events. The unusually wide zone of damage caused by the 2001 Kunlun earthquake has been attributed to the effects of the sonic boom developed in such earthquakes. Slow earthquake ruptures travel at unusually low velocities. A particularly dangerous form of slow earthquake

576-622: A forest of 13 non-uniform tubes which appear to rise fluidly through the building. Architecturally, the building is considered an important milestone in Ito's career. "In terms of architectural genre the Sendai Mediatheque was a pioneering example of attempts to use new notions of 'media' as an architectural concept." This project's importance is derived from its poetic imagery, avant-garde program and technical innovation. In Ito's own words: Sendai Mediatheque embodies our proposal for

672-458: A particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word earthquake is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining , fracking , and nuclear tests . The initial point of rupture is called the hypocenter or focus, while

768-560: A particular location in the Earth is the average rate of seismic energy release per unit volume. One of the most devastating earthquakes in recorded history was the 1556 Shaanxi earthquake , which occurred on 23 January 1556 in Shaanxi , China. More than 830,000 people died. Most houses in the area were yaodongs —dwellings carved out of loess hillsides—and many victims were killed when these structures collapsed. The 1976 Tangshan earthquake , which killed between 240,000 and 655,000 people,

864-442: A revived masterpiece, some have condemned it as a "fake," and others are ambivalent. "[T]his building is not supposed to exist," asserted Paul Goldberger at the time. During planning, Philip Johnson wondered, "The problem before us is should a dream be realized or not? We have made such a myth of that building. Shouldn’t it be left in the sacred vault of the memory bank?" Architect Lance Hosey has thoroughly documented reactions to

960-765: A single rupture) are approximately 1,000 km (620 mi). Examples are the earthquakes in Alaska (1957) , Chile (1960) , and Sumatra (2004) , all in subduction zones. The longest earthquake ruptures on strike-slip faults, like the San Andreas Fault ( 1857 , 1906 ), the North Anatolian Fault in Turkey ( 1939 ), and the Denali Fault in Alaska ( 2002 ), are about half to one third as long as

1056-438: A uniformity across each face of the cube during the day. The main (south-facing) facade is double-glazed and functions as part of the building's climate control system. The materials which compose the skin are glass, steel panels, and aluminum mesh. The most striking structural elements are the tubes, composed of thick-walled steel pipes; they range in size from 7 to 30 inches In diameter. Although they appear to be continuous,

1152-450: A year after it was completed. Between 1983 and 1986, a group of Catalan architects formed the Mies van der Rohe Foundation and reconstructed the pavilion permanently, based on historical drawings and rediscovered footings on the site. The reconstruction has been a popular tourist destination, but it also has been controversial among architects, critics, and historians. Some have hailed it as

1248-525: Is a theory that earthquakes can recur in a regular pattern. Earthquake clustering has been observed, for example, in Parkfield, California where a long-term research study is being conducted around the Parkfield earthquake cluster. An aftershock is an earthquake that occurs after a previous earthquake, the mainshock. Rapid changes of stress between rocks, and the stress from the original earthquake are

1344-524: Is converted into heat generated by friction. Therefore, earthquakes lower the Earth's available elastic potential energy and raise its temperature, though these changes are negligible compared to the conductive and convective flow of heat out from the Earth's deep interior. There are three main types of fault, all of which may cause an interplate earthquake : normal, reverse (thrust), and strike-slip. Normal and reverse faulting are examples of dip-slip, where

1440-400: Is divided into 754 Flinn–Engdahl regions (F-E regions), which are based on political and geographical boundaries as well as seismic activity. More active zones are divided into smaller F-E regions whereas less active zones belong to larger F-E regions. Standard reporting of earthquakes includes its magnitude , date and time of occurrence, geographic coordinates of its epicenter , depth of

1536-654: Is influenced by tectonic movements along faults, including normal, reverse (thrust), and strike-slip faults, with energy release and rupture dynamics governed by the elastic-rebound theory . Efforts to manage earthquake risks involve prediction, forecasting, and preparedness, including seismic retrofitting and earthquake engineering to design structures that withstand shaking. The cultural impact of earthquakes spans myths, religious beliefs, and modern media, reflecting their profound influence on human societies. Similar seismic phenomena, known as marsquakes and moonquakes , have been observed on other celestial bodies, indicating

1632-420: Is located in the heart of the city of Sendai, only a few blocks away from the city hall. The building sits flush with Jozenji street, a six-lane divided boulevard , although there are entrances on all four sides of the building. The diaphanous glass and metal façade of the institution, while differing from the mainly white, opaque volumes of the neighboring buildings, blends harmoniously with the environment during

1728-545: Is probably a statistical fluctuation rather than a systematic trend. More detailed statistics on the size and frequency of earthquakes is available from the United States Geological Survey. A recent increase in the number of major earthquakes has been noted, which could be explained by a cyclical pattern of periods of intense tectonic activity, interspersed with longer periods of low intensity. However, accurate recordings of earthquakes only began in

1824-423: Is proportional to the area of the fault that ruptures and the stress drop. Therefore, the longer the length and the wider the width of the faulted area, the larger the resulting magnitude. The most important parameter controlling the maximum earthquake magnitude on a fault, however, is not the maximum available length, but the available width because the latter varies by a factor of 20. Along converging plate margins,

1920-410: Is the tsunami earthquake , observed where the relatively low felt intensities, caused by the slow propagation speed of some great earthquakes, fail to alert the population of the neighboring coast, as in the 1896 Sanriku earthquake . During an earthquake, high temperatures can develop at the fault plane, increasing pore pressure and consequently vaporization of the groundwater already contained within

2016-474: Is the differentiation between levels is the furniture designed by several different designers which through color, style, and layout becomes one of the most prominent identifying features of a particular floor. The structure of the Sendai Mediatheque is composed of three main elements: tubes, plates and skin. The plates (floor slabs) are composed of a honeycomb-like network of steel sections infilled with lightweight concrete. The steel honeycomb structure allows

2112-413: Is the exotic materials Mies chooses to use. Plates of high-grade stone materials like veneers of Tinos verde antico marble and golden onyx as well as tinted glass of grey, green, white, as well as translucent glass, perform exclusively as spatial dividers. Because this was planned as an exhibition pavilion, it was intended to exist only temporarily. The building was torn down in early 1930, not even

2208-458: The 1960 Valdivia earthquake in Chile, the largest ever recorded at 9.5 magnitude. Earthquakes result in various effects, such as ground shaking and soil liquefaction , leading to significant damage and loss of life. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami . Earthquakes can trigger landslides . Earthquakes' occurrence

2304-400: The 1980 eruption of Mount St. Helens . Earthquake swarms can serve as markers for the location of the flowing magma throughout the volcanoes. These swarms can be recorded by seismometers and tiltmeters (a device that measures ground slope) and used as sensors to predict imminent or upcoming eruptions. A tectonic earthquake begins as an area of initial slip on the fault surface that forms

2400-587: The 2004 Indian Ocean earthquake is simultaneously one of the deadliest earthquakes in history. Earthquakes that caused the greatest loss of life, while powerful, were deadly because of their proximity to either heavily populated areas or the ocean, where earthquakes often create tsunamis that can devastate communities thousands of kilometers away. Regions most at risk for great loss of life include those where earthquakes are relatively rare but powerful, and poor regions with lax, unenforced, or nonexistent seismic building codes. Tectonic earthquakes occur anywhere on

2496-499: The Himalayan Mountains . With the rapid growth of mega-cities such as Mexico City, Tokyo, and Tehran in areas of high seismic risk , some seismologists are warning that a single earthquake may claim the lives of up to three million people. While most earthquakes are caused by the movement of the Earth's tectonic plates , human activity can also produce earthquakes. Activities both above ground and below may change

2592-588: The Mies van der Rohe Foundation presented the first edition of the Lilly Reich Grant for equality in architecture. The recipient of the inaugural grant was Re-enactment: Lilly Reich's work occupies the Barcelona Pavilion submitted by Laura Martínez de Guereñu. In 2020, the second grant was awarded to [On Set with] Lilly Reich submitted by Laura Lizondo Sevilla, Débora Domingo Calabuig, and Avelina Prat García. The third grant, in 2022,

2688-426: The brittle-ductile transition zone and upwards by the ground surface. The mechanics of this process are poorly understood because it is difficult either to recreate such rapid movements in a laboratory or to record seismic waves close to a nucleation zone due to strong ground motion. In most cases, the rupture speed approaches, but does not exceed, the shear wave (S wave) velocity of the surrounding rock. There are

2784-413: The least principal stress. Strike-slip faulting is intermediate between the other two types described above. This difference in stress regime in the three faulting environments can contribute to differences in stress drop during faulting, which contributes to differences in the radiated energy, regardless of fault dimensions. For every unit increase in magnitude, there is a roughly thirty-fold increase in

2880-406: The lithosphere that creates seismic waves . Earthquakes can range in intensity , from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at

2976-479: The "floating roof". Mies's response to the proposal by von Schnitzler was radical. After rejecting the original site for aesthetic reasons, Mies agreed to a quiet site at the narrow side of a wide, diagonal axis, where the pavilion would still offer viewpoints and a route leading to one of the exhibition's main attractions, the Poble Espanyol . The pavilion was to be bare, with no exhibits, leaving only

3072-480: The 1924 Dawes Plan . The pavilion for the International Exhibition was supposed to represent the new Weimar Germany : democratic, culturally progressive, prospering, and thoroughly pacifist; a self-portrait through architecture. The Commissioner, Georg von Schnitzler said it should give "voice to the spirit of a new era". This concept was carried out with the realization of the " free plan " and

3168-553: The 20th century and has been inferred for older anomalous clusters of large earthquakes in the Middle East. It is estimated that around 500,000 earthquakes occur each year, detectable with current instrumentation. About 100,000 of these can be felt. Minor earthquakes occur very frequently around the world in places like California and Alaska in the U.S., as well as in El Salvador, Mexico, Guatemala, Chile, Peru, Indonesia,

3264-433: The 21st century. Seismic waves travel through the Earth's interior and can be recorded by seismometers at great distances. The surface-wave magnitude was developed in the 1950s as a means to measure remote earthquakes and to improve the accuracy for larger events. The moment magnitude scale not only measures the amplitude of the shock but also takes into account the seismic moment (total rupture area, average slip of

3360-399: The Earth's core was located in 1913 by Beno Gutenberg . S waves and later arriving surface waves do most of the damage compared to P waves. P waves squeeze and expand the material in the same direction they are traveling, whereas S waves shake the ground up and down and back and forth. Earthquakes are not only categorized by their magnitude but also by the place where they occur. The world

3456-484: The Earth. Also, the depth of the hypocenter can be computed roughly. P wave speed S waves speed As a consequence, the first waves of a distant earthquake arrive at an observatory via the Earth's mantle. On average, the kilometer distance to the earthquake is the number of seconds between the P- and S wave times 8. Slight deviations are caused by inhomogeneities of subsurface structure. By such analysis of seismograms,

3552-573: The Philippines, Iran, Pakistan, the Azores in Portugal, Turkey, New Zealand, Greece, Italy, India, Nepal, and Japan. Larger earthquakes occur less frequently, the relationship being exponential ; for example, roughly ten times as many earthquakes larger than magnitude 4 occur than earthquakes larger than magnitude 5. In the (low seismicity) United Kingdom, for example, it has been calculated that

3648-482: The artistic management and erection of not only the Barcelona Pavilion, but for the buildings for all the German sections at the 1929 International Exhibition. However, Mies had severe time constraints—he had to design the Barcelona Pavilion in less than a year—and was also dealing with uncertain economic conditions. In the years following World War I , Germany started to turn around. The economy started to recover after

3744-463: The average recurrences are: an earthquake of 3.7–4.6 every year, an earthquake of 4.7–5.5 every 10 years, and an earthquake of 5.6 or larger every 100 years. This is an example of the Gutenberg–Richter law . The number of seismic stations has increased from about 350 in 1931 to many thousands today. As a result, many more earthquakes are reported than in the past, but this is because of

3840-518: The beginning. However, it differs from universal space in that there is considerable variation depending on where you are in the building. For example, the spaces to the South and to the North are quite distinct because of the quality of light and wall surfaces, so their uses are determined by the given spatial conditions to some degree - although quite loosely, of course. Basically, universal space implies

3936-404: The brittle crust. Thus, earthquakes with magnitudes much larger than 8 are not possible. In addition, there exists a hierarchy of stress levels in the three fault types. Thrust faults are generated by the highest, strike-slip by intermediate, and normal faults by the lowest stress levels. This can easily be understood by considering the direction of the greatest principal stress, the direction of

4032-503: The building survived the March 2011 earthquake with little to no damage. The tubes also house vertical circulation of air, water, electricity, light and people within the building. The constant motion of people through the stairs and elevators, as well as the glow of light passing through these tubes creates a perceptual link between the floors, and the functions they house, which might otherwise have felt isolated from one another.

Since the Pavilion's reconstruction in the 1980s, the Mies van der Rohe Foundation has invited leading artists and architects to temporarily alter the Pavilion. These installations and alterations, called "interventions", have kept

4224-534: The building, including the Barcelona chair , are still in production. It has inspired many important modernist buildings. The original structure was demolished in 1930, and the existing reconstruction was completed in 1986. Mies and Reich were offered the commission of this building in 1928 after his successful administration of the 1927 Werkbund exhibition in Stuttgart . The German Republic entrusted Mies with

4320-566: The cause of other earthquakes in the past century. A Columbia University paper suggested that the 8.0 magnitude 2008 Sichuan earthquake was induced by loading from the Zipingpu Dam , though the link has not been conclusively proved. The instrumental scales used to describe the size of an earthquake began with the Richter scale in the 1930s. It is a relatively simple measurement of an event's amplitude, and its use has become minimal in

4416-464: The city into the building continues throughout all seven floors above ground; a gesture which reinforces Ito's resistance to the rigid limitation of activities in the building to within predetermined areas. ...this building has many free spaces, that is, spaces that are not intended, as rooms are, to serve specific functions. Such spaces exist, for example, between the tubes and the building perimeter. Visitors will be able to use such spaces as they use

4512-432: The city streets, for various activities. ... I am hoping that, as such spaces are used, the Mediatheque will become a place for thinking about the city. The Sendai Mediatheque is a mixed-program public facility which combines library and art gallery functions located in the city of Sendai, Japan. Toyo Ito's winning entry for an open competition commissioned by the city of Sendai in 1995, the innovative building opened to

The ground floor is conceived as an extension of the street, with a cafe, bookstore, and event plaza sitting freely (without partitions) within the ground floor space, with views to the sidewalk through the double-glazed facade facing Jozenji Street. This extension of

4704-529: The dip angle of the rupture plane is very shallow, typically about 10 degrees. Thus, the width of the plane within the top brittle crust of the Earth can reach 50–100 km (31–62 mi) (such as in Japan, 2011 , or in Alaska, 1964 ), making the most powerful earthquakes possible. The majority of tectonic earthquakes originate in the Ring of Fire at depths not exceeding tens of kilometers. Earthquakes occurring at

4800-477: The direction of the Poble Espanyol. The visitors were not meant to be led in a straight line through the building, but to take continuous turnabouts. The walls not only created space, but also directed visitor's movements. This was achieved by wall surfaces being displaced against each other, running past each other, and creating a space that became narrower or wider. Another unique feature of this building

4896-678: The displacement along the fault is in the direction of dip and where movement on them involves a vertical component. Many earthquakes are caused by movement on faults that have components of both dip-slip and strike-slip; this is known as oblique slip. The topmost, brittle part of the Earth's crust, and the cool slabs of the tectonic plates that are descending into the hot mantle, are the only parts of our planet that can store elastic energy and release it in fault ruptures. Rocks hotter than about 300 °C (572 °F) flow in response to stress; they do not rupture in earthquakes. The maximum observed lengths of ruptures and mapped faults (which may break in

4992-439: The distance from the earthquake and the underlying rock or soil makeup. The first scale for measuring earthquake magnitudes was developed by Charles Francis Richter in 1935. Subsequent scales ( seismic magnitude scales ) have retained a key feature, where each unit represents a ten-fold difference in the amplitude of the ground shaking and a 32-fold difference in energy. Subsequent scales are also adjusted to have approximately

5088-554: The early 1900s, so it is too early to categorically state that this is the case. Most of the world's earthquakes (90%, and 81% of the largest) take place in the 40,000-kilometre-long (25,000 mi), horseshoe-shaped zone called the circum-Pacific seismic belt, known as the Pacific Ring of Fire , which for the most part bounds the Pacific plate . Massive earthquakes tend to occur along other plate boundaries too, such as along

5184-403: The earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane . The sides of a fault move past each other smoothly and aseismically only if there are no irregularities or asperities along the fault surface that increases the frictional resistance. Most fault surfaces do have such asperities, which leads to a form of stick-slip behavior . Once

5280-426: The earthquakes strike a fault in clusters, each triggered by the shaking or stress redistribution of the previous earthquakes. Similar to aftershocks but on adjacent segments of fault, these storms occur over the course of years, with some of the later earthquakes as damaging as the early ones. Such a pattern was observed in the sequence of about a dozen earthquakes that struck the North Anatolian Fault in Turkey in

5376-504: The energy released. For instance, an earthquake of magnitude 6.0 releases approximately 32 times more energy than a 5.0 magnitude earthquake and a 7.0 magnitude earthquake releases 1,000 times more energy than a 5.0 magnitude earthquake. An 8.6-magnitude earthquake releases the same amount of energy as 10,000 atomic bombs of the size used in World War II . This is so because the energy released in an earthquake, and thus its magnitude,

5472-458: The fact that no single earthquake in the sequence is the main shock, so none has a notably higher magnitude than another. An example of an earthquake swarm is the 2004 activity at Yellowstone National Park . In August 2012, a swarm of earthquakes shook Southern California 's Imperial Valley , showing the most recorded activity in the area since the 1970s. Sometimes a series of earthquakes occur in what has been called an earthquake storm , where

5568-462: The fault has locked, continued relative motion between the plates leads to increasing stress and, therefore, stored strain energy in the volume around the fault surface. This continues until the stress has risen sufficiently to break through the asperity, suddenly allowing sliding over the locked portion of the fault, releasing the stored energy . This energy is released as a combination of radiated elastic strain seismic waves , frictional heating of

5664-411: The fault plane that holds it in place, and fluids can exert a lubricating effect. As thermal overpressurization may provide positive feedback between slip and strength fall at the fault plane, a common opinion is that it may enhance the faulting process instability. After the mainshock, the pressure gradient between the fault plane and the neighboring rock causes a fluid flow that increases pore pressure in

5760-418: The fault surface, and cracking of the rock, thus causing an earthquake. This process of gradual build-up of strain and stress punctuated by occasional sudden earthquake failure is referred to as the elastic-rebound theory . It is estimated that only 10 percent or less of an earthquake's total energy is radiated as seismic energy. Most of the earthquake's energy is used to power the earthquake fracture growth or

The Japan Meteorological Agency seismic intensity scale , the Medvedev–Sponheuer–Karnik scale , and the Mercalli intensity scale are based on the observed effects and are related to the intensity of shaking. The shaking of the earth is a common phenomenon that has been experienced by humans from the earliest of times. Before the development of strong-motion accelerometers,

5952-417: The focus. Once the rupture has been initiated, it begins to propagate away from the focus, spreading out along the fault surface. Lateral propagation will continue until either the rupture reaches a barrier, such as the end of a fault segment, or a region on the fault where there is insufficient stress to allow continued rupture. For larger earthquakes, the depth extent of rupture will be constrained downwards by

6048-406: The force that "pushes" the rock mass during the faulting. In the case of normal faults, the rock mass is pushed down in a vertical direction, thus the pushing force ( greatest principal stress) equals the weight of the rock mass itself. In the case of thrusting, the rock mass "escapes" in the direction of the least principal stress, namely upward, lifting the rock mass, and thus, the overburden equals

6144-493: The ground level directly above it is the epicenter . Earthquakes are primarily caused by geological faults , but also by volcanic activity , landslides, and other seismic events. The frequency, type, and size of earthquakes in an area define its seismic activity, reflecting the average rate of seismic energy release. Significant historical earthquakes include the 1556 Shaanxi earthquake in China, with over 830,000 fatalities, and

6240-410: The intensity of a seismic event was estimated based on the observed effects. Magnitude and intensity are not directly related and calculated using different methods. The magnitude of an earthquake is a single value that describes the size of the earthquake at its source. Intensity is the measure of shaking at different locations around the earthquake. Intensity values vary from place to place, depending on

6336-476: The lengths along subducting plate margins, and those along normal faults are even shorter. Normal faults occur mainly in areas where the crust is being extended such as a divergent boundary . Earthquakes associated with normal faults are generally less than magnitude 7. Maximum magnitudes along many normal faults are even more limited because many of them are located along spreading centers, as in Iceland, where

An aftershock is in the same region as the main shock but always of a smaller magnitude, however, they can still be powerful enough to cause even more damage to buildings that were already previously damaged from the mainshock. If an aftershock is larger than

6624-414: The mainshock, the aftershock is redesignated as the mainshock and the original main shock is redesignated as a foreshock . Aftershocks are formed as the crust around the displaced fault plane adjusts to the effects of the mainshock. Earthquake swarms are sequences of earthquakes striking in a specific area within a short period. They are different from earthquakes followed by a series of aftershocks by

Indeed, reinforcing the subtle differences in spatial composition provided by the tubes, each level's ceiling height and design, partition material and lighting colors reinforce the differentiation in uses to create space which could not fairly be described as homogeneous. Perhaps most striking, however,

The Mediatheque's seven levels of facilities offer a range of services including a conventional book- lending library , an extensive collection of film and audio recordings with stations for both viewing and editing, a theater , to a cafe and bookstore, all housed in a nearly cubic glass enclosure. The seven platforms are supported by what Ito calls "characterizing" architectural elements:

7200-414: The reconstruction, concluding that while the reconstruction is a better physical artifact, the original was an irreplaceable product of its sociopolitical context. The Pavilion was not only a pioneer for construction forms with a fresh, disciplined understanding of space, but also for modelling new opportunities for an association of free art and architecture. Mies placed Georg Kolbe 's Alba ("Dawn") in

7296-530: The rock. In the coseismic phase, such an increase can significantly affect slip evolution and speed, in the post-seismic phase it can control the Aftershock sequence because, after the main event, pore pressure increase slowly propagates into the surrounding fracture network. From the point of view of the Mohr-Coulomb strength theory , an increase in fluid pressure reduces the normal stress acting on

An earthquake's point of initial rupture is called its hypocenter or focus. The epicenter is the point at ground level directly above the hypocenter. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at

Although the mass media commonly reports earthquake magnitudes as "Richter magnitude" or "Richter scale", standard practice by most seismological authorities is to express an earthquake's strength on the moment magnitude scale, which is based on the actual energy released by an earthquake, the static seismic moment. Every earthquake produces different types of seismic waves, which travel through rock with different velocities: Propagation velocity of

7584-464: The seismic waves through solid rock ranges from approx. 3 km/s (1.9 mi/s) up to 13 km/s (8.1 mi/s), depending on the density and elasticity of the medium. In the Earth's interior, the shock- or P waves travel much faster than the S waves (approx. relation 1.7:1). The differences in travel time from the epicenter to the observatory are a measure of the distance and can be used to image both sources of earthquakes and structures within

7680-491: The site also forms a smaller water basin. This is where the statue by Georg Kolbe sits. The roof plates, relatively small, are supported by the chrome-clad, cruciform columns. This gives the impression of a hovering roof. Robin Evans said that the reflective columns appear to be struggling to hold the "floating" roof plane down, not to be bearing its weight. Mies wanted this building to become "an ideal zone of tranquillity" for

7776-402: The small water basin, leaving the larger one all the more empty. The sculpture also ties into the highly reflective materials Mies used—he chose the place where these optical effects would have the strongest impact; the building offers multiple views of Alba . "From now on, in the sense of equality for juxtaposing building and visual work, sculptures were no longer to be applied retrospectively to

7872-509: The state-of-the-art media. Ito, in creating the Sendai Mediatheque, acknowledged that it would be an institution devoted to accommodating changing technologies. While the design of the Mediatheque is meant to encourage a flexibility of use through the blurring of boundaries found in traditional library and museum typologies, Ito resists the characterization of the space inside the center as the “homogeneous” or "universal" space of modernism. "The Sendai Mediatheque has been constantly changing from

7968-422: The stresses and strains on the crust, including building reservoirs, extracting resources such as coal or oil, and injecting fluids underground for waste disposal or fracking . Most of these earthquakes have small magnitudes. The 5.7 magnitude 2011 Oklahoma earthquake is thought to have been caused by disposing wastewater from oil production into injection wells , and studies point to the state's oil industry as

8064-472: The structure accompanying a single sculpture and specially-designed furniture (the Barcelona Chair ). This lack of accommodation enabled Mies to treat the Pavilion as a continuous space; blurring inside and outside. "The design was predicated on an absolute distinction between structure and enclosure—a regular grid of cruciform steel columns interspersed by freely spaced planes". However, the structure

8160-490: The surrounding fracture networks; such an increase may trigger new faulting processes by reactivating adjacent faults, giving rise to aftershocks. Analogously, artificial pore pressure increase, by fluid injection in Earth's crust, may induce seismicity . Tides may trigger some seismicity . Most earthquakes form part of a sequence, related to each other in terms of location and time. Most earthquake clusters consist of small tremors that cause little to no damage, but there

8256-443: The thickness of the brittle layer is only about six kilometres (3.7 mi). Reverse faults occur in areas where the crust is being shortened such as at a convergent boundary . Reverse faults, particularly those along convergent boundaries, are associated with the most powerful earthquakes (called megathrust earthquakes ) including almost all of those of magnitude 8 or more. Megathrust earthquakes are responsible for about 90% of

8352-461: The total seismic moment released worldwide. Strike-slip faults are steep structures where the two sides of the fault slip horizontally past each other; transform boundaries are a particular type of strike-slip fault. Strike-slip faults, particularly continental transforms , can produce major earthquakes up to about magnitude 8. Strike-slip faults tend to be oriented near vertically, resulting in an approximate width of 10 km (6.2 mi) within

8448-460: The tubes create links throughout the full height of the building, they are often glazed to provide fire protection between floors. In the plane of a specific floor, the non-standard layout loosely manipulates the layout of the floor plan. The size of each tube is determined by its internal function – stairs, elevator, light shaft. Moreover, since the exact dimensions of the tubes vary from floor to floor, this variation, along with differentiation in

8544-399: The tubes were actually manufactured in floor-height segments and were assembled sequentially, floor-by-floor. The tubes perform a number of functions. Firstly, they serve to structurally support the building. The four tubes closest to the outer corners of the plates were designed to resist a 400-year earthquake , while the others resist the vertical gravity loads. As a test to its integrity,

8640-505: The universality of such events beyond Earth. An earthquake is the shaking of the surface of Earth resulting from a sudden release of energy in the lithosphere that creates seismic waves . Earthquakes may also be referred to as quakes , tremors , or temblors . The word tremor is also used for non-earthquake seismic rumbling . In its most general sense, an earthquake is any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by

8736-436: The vast improvement in instrumentation, rather than an increase in the number of earthquakes. The United States Geological Survey (USGS) estimates that, since 1900, there have been an average of 18 major earthquakes (magnitude 7.0–7.9) and one great earthquake (magnitude 8.0 or greater) per year, and that this average has been relatively stable. In recent years, the number of major earthquakes per year has decreased, though this

8832-424: The weary visitor, who should be invited into the pavilion on the way to the next attraction. Since the pavilion lacked a real exhibition space, the building itself was to become the exhibit. The pavilion was designed to "block" any passage through the site, rather, one would have to go through the building. Visitors would enter by going up a few stairs, and due to the slightly sloped site, would leave at ground level in

8928-399: Was awarded to the submission Anna Bofill Levi . Architecture as a Counter-Melody (1977–1996) by María-Elia Gutiérrez Mozo, José Parra Martínez, Ana Gilsanz Díaz, and Joaquín Arnau Amo. Earthquake An earthquake  – also called a quake , tremor , or temblor  – is the shaking of the Earth 's surface resulting from a sudden release of energy in

9024-409: Was more of a hybrid style, some of these planes also acted as supports. The floor plan is very simple. The entire building rests on a plinth of travertine. A southern U-shaped enclosure, also of travertine, helps form a service annex and a large water basin. The floor slabs of the pavilion project out and over the pool—once again connecting inside and out. Another U-shaped wall on the opposite side of

9120-475: Was the German Pavilion for the 1929 International Exposition in Barcelona , Spain . This building was used for the official opening of the German section of the exhibition. It is an important building in the history of modern architecture , known for its simple form and its spectacular use of extravagant materials, such as marble , red onyx and travertine . Furnishings specifically designed for

9216-641: Was the deadliest of the 20th century. The 1960 Chilean earthquake is the largest earthquake that has been measured on a seismograph, reaching 9.5 magnitude on 22 May 1960. Its epicenter was near Cañete, Chile. The energy released was approximately twice that of the next most powerful earthquake, the Good Friday earthquake (27 March 1964), which was centered in Prince William Sound , Alaska. The ten largest recorded earthquakes have all been megathrust earthquakes ; however, of these ten, only
