Kailua-Kona is an unincorporated community and census-designated place (CDP) in Hawaii County , Hawaii , United States . It's most commonly referred to simply as Kona (a name it shares with the district to which it belongs ), but also as Kona Town , and occasionally as Kailua (a name it shares with a community on the windward side of Oʻahu ), thus its less frequent use. Kailua-Kona is the second-largest settlement on the island of Hawaii (after Hilo ) and the largest on the island's west side, where it is the center of commerce and the tourist industry. Kailua-Kona is served by Kona International Airport , just to the north in the adjacent CDP of Kalaoa . The population was 19,713 at the 2020 census , up from 11,975 at the 2010 census .
63-417: Kailua-Kona was the closest major settlement to the epicenter of the 2006 Kiholo Bay earthquake . Kailua-Kona's boundaries were altered significantly for the 2020 census . The eastern portion of Kailua-Kona became part of the neighboring Holualoa CDP, while the western portion of Holualoa became part of Kailua-Kona. The community was established by King Kamehameha I to be his seat of government when he
126-407: A seismometer is to locate the initiating points of earthquake epicenters. The secondary purpose, of determining the 'size' or magnitude must be calculated after the precise location is known. The earliest seismographs were designed to give a sense of the direction of the first motions from an earthquake. The Chinese frog seismograph would have dropped its ball in the general compass direction of
189-507: A combined question and a MENA category, while also collecting additional detail to enable data disaggregation. The OMB states, "many federal programs are put into effect based on the race data obtained from the decennial census (i.e., promoting equal employment opportunities; assessing racial disparities in health and environmental risks). Race data is also critical for the basic research behind many policy decisions. States require this data to meet legislative redistricting requirements. The data
252-487: A macroseismic epicenter can be given. The word is derived from the Neo-Latin noun epicentrum , the latinisation of the ancient Greek adjective ἐπίκεντρος ( epikentros ), "occupying a cardinal point, situated on a centre", from ἐπί ( epi ) "on, upon, at" and κέντρον ( kentron ) " centre ". The term was coined by Irish seismologist Robert Mallet . It is also used to mean "center of activity", as in "Travel
315-440: A moving graph, driven by a clock mechanism. This was the first seismogram , which allowed precise timing of the first ground motion , and an accurate plot of subsequent motions. From the first seismograms, as seen in the figure, it was noticed that the trace was divided into two major portions. The first seismic wave to arrive was the P wave , followed closely by the S wave . Knowing the relative 'velocities of propagation', it
378-533: A person's origins considered in the census. Thus, in addition to their race or races, all respondents are categorized by membership in one of two ethnic categories, which are "Hispanic or Latino" and "Not Hispanic or Latino." However, the practice of separating "race" and "ethnicity" as different categories has been criticized both by the American Anthropological Association and members of US Commission on Civil Rights . In 1997,
441-804: A popular snorkeling location. Boat tours that allow tourists to watch dolphins and whales, swim with manta rays, turtles and fish in the ocean usually depart from the Kailua-Kona pier or nearby Honokohau and Keauhou harbors. Kailua-Kona is served by television station KLEI and by the newspaper West Hawaii Today , which is owned by Canadian publisher Black Press Media (Black Press Group Ltd.)—also known simply as Black Press—whose headquarters are in Surrey, British Columbia , Canada . The Hawaii Department of Education operates public schools. Kealakehe Elementary School, Kahakai Elementary School, Kealakehe Intermediate School, and Kealakehe High School are in
504-524: A race. Enumerators were instructed that all people born in Mexico, or whose parents were born in Mexico, should be listed as Mexicans, and not under any other racial category. In prior censuses and in 1940, enumerators were instructed to list Mexican Americans as white, perhaps because some of them were of white background (mainly Spanish), many others mixed white and Native American and some of them Native American. The supplemental American Indian questionnaire
567-424: A seismic array. The emphasis is on precision since much can be learned about the fault mechanics and seismic hazard , if the locations can be determined to be within a kilometer or two, for small earthquakes. For this, computer programs use an iterative process, involving a 'guess and correction' algorithm. As well, a very good model of the local crustal velocity structure is required: seismic velocities vary with
630-675: A separate question. The racial categories represent a social-political construct for the race or races that respondents consider themselves to be and, "generally reflect a social definition of race recognized in this country". The OMB defines the concept of race as outlined for the census to be not "scientific or anthropological", and takes into account "social and cultural characteristics as well as ancestry", using "appropriate scientific methodologies" that are not "primarily biological or genetic in reference." The race categories include both racial and national-origin groups. Race and ethnicity are considered separate and distinct identities, with

Data on ethnic groups are important for putting into effect a number of federal statutes (i.e., enforcing bilingual election rules under the Voting Rights Act and monitoring/enforcing equal employment opportunities under the Civil Rights Act ). Data on ethnic groups is also needed by local governments to run programs and meet legislative requirements (i.e., identifying segments of

Tourism also saw a downturn in the late 2000s but has since seen some resurgence. Visitor air arrivals alone increased about 160% from 2010 to 2017. The University of Hawaiʻi held its first classes at the new Hawaii Community College Palamanui Campus in 2015. Since the early 2000s
1071-859: The Secretary of State , directed US Marshals to collect data from all 13 original states, and from the Southwest Territory . The census was not conducted in Vermont until 1791, after that state's admission to the Union as the 14th state on March 4 of that year. Some doubt surrounded the numbers, as President George Washington and Thomas Jefferson maintained the population was undercounted. The potential reasons Washington and Jefferson may have thought this could be refusal to participate, poor public transportation and roads, spread-out population, and restraints of current technology. No microdata from
1134-476: The US Constitution and applicable laws. The law required that every household be visited, that completed census schedules be posted in two of the most public places within each jurisdiction, remain for the inspection of all concerned, and that "the aggregate amount of each description of persons" for every district be transmitted to the president . The US Marshals were also responsible for governing
1197-417: The "Color or Race" question was slightly modified, removing the term "Mulatto". Also, there was an inclusion of an "Indian Population Schedule" in which "enumerators were instructed to use a special expanded questionnaire for American Indians living on reservations or in family groups off of reservations." This expanded version included the question "Fraction of person's lineage that is white." The 1910 census

Kona coffee is the variety of Coffea arabica cultivated on
1575-519: The OMB built on the 1997 guidelines and suggested the addition of a Middle Eastern or North African (MENA) racial category and considered combining racial and ethnic categories into one question. In March 2024, the Office of Management and Budget published revisions to Statistical Policy Directive No. 15: Standards for Maintaining, Collecting, and Presenting Federal Data on Race and Ethnicity that included
1638-405: The OMB issued a Federal Register notice regarding revisions to the standards for the classification of federal data on race and ethnicity. The OMB developed race and ethnic standards in order to provide "consistent data on race and ethnicity throughout the federal government ". The development of the data standards stem in large measure from new responsibilities to enforce civil rights laws. Among
1701-418: The census form. In 1800 and 1810, the age question regarding free white males was more detailed with five cohorts and included All other free persons, except "Indians not taxed", and "Slaves". The 1820 census built on the questions asked in 1810 by asking age questions about slaves. Also the term "colored" entered the census nomenclature. In addition, a question stating "Number of foreigners not naturalized"
1764-418: The census. About one-third of the original census data has been lost or destroyed since documentation. The data was lost in 1790–1830, and included data from Connecticut , Delaware , Georgia , Maine , Maryland , Massachusetts , New Hampshire , New Jersey , New York , North Carolina , Pennsylvania , Rhode Island , South Carolina , Vermont , and Virginia . However, the census was proven factual and
1827-483: The changes, The OMB issued the instruction to "mark one or more races" after noting evidence of increasing numbers of mixed-race children and wanting to record diversity in a measurable way after having received requests by people who wanted to be able to acknowledge theirs and their children's full ancestry, rather than identifying with only one group. Prior to this decision, the census and other government data collections asked people to report singular races. As of 2023,
1890-485: The city was $ 40,874, and the median income for a family was $ 46,657. Males had a median income of $ 30,353 versus $ 26,471 for females. The per capita income for the CDP was $ 20,624. 10.8% of the population and 6.5% of families were below the poverty line . Out of the total population, 11.9% of those under the age of 18 and 3.9% of those 65 and older were living below the poverty line. Kailua-Kona saw an economic downturn during
1953-657: The decision and make sure the federal government treated Hispanics as white. The State Department, the Census Bureau, the Labor Department, and other government agencies therefore made sure to uniformly classify people of Mexican descent as white. This policy encouraged the League of United Latin American Citizens in its quest to minimize discrimination by asserting their whiteness. The 1940 census

2016-536: The design of the population questionnaire. Residents were still listed individually, but a new questionnaire sheet was used for each family. Additionally, this was the first year that the census distinguished among different Asian ethnic groups, such as Japanese and Chinese , due to increased immigration. This census also marked the beginning of the term "race" in the questionnaires. Enumerators were instructed to write "White", "Black", "Mulatto", " Quadroon ", "Octoroon", "Chinese", "Japanese", or " Indian ". During 1900,
2079-403: The earthquake, assuming a strong positive pulse. We now know that first motions can be in almost any direction depending on the type of initiating rupture ( focal mechanism ). The first refinement that allowed a more precise determination of the location was the use of a time scale. Instead of merely noting, or recording, the absolute motions of a pendulum , the displacements were plotted on
2142-456: The existence of most of this data can be confirmed in many secondary sources pertaining to the first census. Census data included the name of the head of the family and categorized inhabitants as: free white males at least 16 years of age (to assess the country's industrial and military potential), free white males under 16 years of age, free white females, all other free persons (reported by sex and color), and slaves . Thomas Jefferson , then
2205-416: The focus and then expands along the fault surface. The rupture stops where the stresses become insufficient to continue breaking the fault (because the rocks are stronger) or where the rupture enters ductile material. The magnitude of an earthquake is related to the total area of its fault rupture. Most earthquakes are small, with rupture dimensions less than the depth of the focus so the rupture doesn't break
2268-487: The free inhabitants schedule about color was a column that was to be left blank if a person were white, marked "B" if a person were black, and marked "M" if a person were mulatto . Slaves were listed by owner, and classified by gender and age, not individually, and the question about color was a column that was to be marked with a "B" if the slave were black and an "M" if mulatto. For 1890, the Census Office changed
2331-505: The hypocenter. Seismic shadowing occurs on the opposite side of the Earth from the earthquake epicenter because the planet's liquid outer core refracts the longitudinal or compressional ( P waves ) while it absorbs the transverse or shear waves ( S waves ). Outside the seismic shadow zone, both types of wave can be detected, but because of their different velocities and paths through the Earth, they arrive at different times. By measuring
2394-598: The late 1800s, Kailua-Kona was primarily a small fishing village. In the late 20th and early 21st centuries, the region has undergone a real estate and construction boom fueled by tourism and investment. In 2014, the Pālamanui Community Forest preserve was created in Kailua-Kona with a goal of preserving and protecting the native trees of Hawai’i. Kailua-Kona is located at 19°39′0″N 155°59′39″W / 19.65000°N 155.99417°W / 19.65000; -155.99417 (19.649973, −155.994028), along
2457-458: The local geology. For P waves, the relation between velocity and bulk density of the medium has been quantified in Gardner's relation . Before the instrumental period of earthquake observation, the epicenter was thought to be the location where the greatest damage occurred, but the subsurface fault rupture may be long and spread surface damage across the entire rupture zone. As an example, in
2520-611: The magnitude 7.9 Denali earthquake of 2002 in Alaska , the epicenter was at the western end of the rupture, but the greatest damage was about 330 km (210 mi) away at the eastern end. Focal depths of earthquakes occurring in continental crust mostly range from 2 to 20 kilometers (1.2 to 12.4 mi). Continental earthquakes below 20 km (12 mi) are rare whereas in subduction zone earthquakes can originate at depths deeper than 600 km (370 mi). During an earthquake, seismic waves propagates in all directions from

2646-708: The part of copy editors". Garner has speculated that these misuses may just be "metaphorical descriptions of focal points of unstable and potentially destructive environments." Race (U.S. Census) In the United States census , the US Census Bureau and the Office of Management and Budget (OMB) define a set of self-identified categories of race and ethnicity chosen by residents, with which they most closely identify. Residents can indicate their origins alongside their race, and are asked specifically whether they are of Hispanic or Latino origin in
2709-435: The population were Hispanic or Latino of any race. There were 3,537 households, out of which 35.0% had children under the age of 18 living with them, 49.6% were married couples living together, 13.6% had a female householder with no husband present, and 31.3% were non-families. 22.6% of all households were made up of individuals, and 7.2% had someone living alone who was 65 years of age or older. The average household size

The 1790 United States census was the first census in the history of the United States. The population of the United States was recorded as 3,929,214 as of Census Day, August 2, 1790, as mandated by Article I, Section 2 of
2835-451: The race of interracial persons. A person with both white and black ancestry (termed "blood") was to be recorded as "Negro", no matter the fraction of that lineage (the " one-drop rule "). A person of mixed black and American Indian ancestry was also to be recorded as "Neg" (for "Negro") unless they were considered to be "predominantly" American Indian and accepted as such within the community. A person with both white and American Indian ancestry

The 1960 census re-added the word "color" to the racial question, and changed "Indian" to "American Indian", as well as adding Hawaiian, Part-Hawaiian, Aleut, and Eskimo. The "Other (print out race)" option was removed. This year's census included "Negro or Black", re-added Korean and the Other race option. East Indians (the term used at that time for people whose ancestry
2961-425: The range of 2,000−10,000 km. Once distances from the epicenter have been calculated from at least three seismographic measuring stations, the point can be located, using trilateration . Epicentral distance is also used in calculating seismic magnitudes as developed by Richter and Gutenberg . The point at which fault slipping begins is referred to as the focus of the earthquake. The fault rupture begins at

3150-498: The street. Churches on the drive include Mokuaikaua Church , Hawaiʻi's first Christian church (the congregation began in 1820), Saint Michael the Archangel Catholic Church , and Living Stones Church, a historical structure built after Mokuaikaua and used as a Christian Missionary landing location in the 1800–1900. Parks include La'aloa Bay (also known as Magic Sands or White Sands Beach) and Kahaluʻu Bay ,
3213-704: The surface, but in high magnitude, destructive earthquakes, surface breaks are common. Fault ruptures in large earthquakes can extend for more than 100 km (62 mi). When a fault ruptures unilaterally (with the epicenter at or near the end of the fault break) the waves are stronger in one direction along the fault. The macroseismic epicenter is the best estimate of the location of the epicenter derived without instrumental data. This may be estimated using intensity data, information about foreshocks and aftershocks, knowledge of local fault systems or extrapolations from data regarding similar earthquakes. For historical earthquakes that have not been instrumentally recorded, only

No, not Spanish/Hispanic Yes, Mexican, Mexican American, Chicano Yes, Puerto Rican Yes, Cuban Yes, other Spanish/Hispanic The racial categories in this year are as they appear in
3339-406: The time difference on any seismograph and the distance on a travel-time graph on which the P wave and S wave have the same separation, geologists can calculate the distance to the quake's epicenter. This distance is called the epicentral distance , commonly measured in ° (degrees) and denoted as Δ (delta) in seismology. The Láska's empirical rule provides an approximation of epicentral distance in
3402-545: The town from wind and rain. As of the census of 2000 , there were 9,870 people, 3,537 households, and 2,429 families residing in Kailua-Kona. The population density was 278.0 inhabitants per square mile (107.3/km). There were 4,322 housing units at an average density of 121.7 units per square mile (47.0 units/km). The racial makeup of the city was 38.7% White , 0.5% Black or African American , 0.5% Native American , 18.3% Asian , 13.2% Pacific Islander , 1.9% from other races , and 27.07% from two or more races. 10.2% of

The median age was 36 years. For every 100 females, there were 98.8 males. For every 100 females age 18 and over, there were 95.8 males. The median income for a household in
3528-451: Was a simple matter to calculate the distance of the earthquake. One seismograph would give the distance, but that could be plotted as a circle, with an infinite number of possibilities. Two seismographs would give two intersecting circles, with two possible locations. Only with a third seismograph would there be a precise location. Modern earthquake location still requires a minimum of three seismometers. Most likely, there are many, forming

The 1850 census had a dramatic shift in the way information about residents was collected. For the first time, free persons were listed individually instead of by head of household. Two questionnaires were used - one for free inhabitants and one for slaves. The question on

"Hin", "Kor", and "Fil" were also added to the "Color or Race" question, signifying Hindu (Asian Indian), Korean, and Filipino, respectively. The biggest change in this census was in racial classification. Enumerators were instructed to no longer use the "Mulatto" classification. Instead, they were given special instructions for reporting
3843-538: Was similar to that of 1900, but it included a reinsertion of "Mulatto" and a question about the "mother tongue" of foreign-born individuals and individuals with foreign-born parents. "Ot" was also added to signify "other races", with space for a race to be written in. This decade's version of the Indian Population Schedule featured questions asking the individual's proportion of white, black, or American Indian lineage. The 1920 census questionnaire
