Album Topics referred to by the same term [REDACTED] This disambiguation page lists articles associated with

82-463: A shield-stage Hualālai has been found just offshore of its northwest rift zone. Tholeiitic basalt , indicative of the submarine subphase of the volcano's construction, has been found in wells driven into the volcano at a depth of 75 ft (23 m). These lavas persisted until an estimated 130,000 years ago. Hualālai entered the post-shield stage , the stage it is now in, about 100,000 years ago. Pumice and trachyte eruptions at Puʻu Waʻawaʻa may be

123-454: A deep source off the coast of the north-western rift zone and are not related to the movement of magma. Hualālai has been a home to native people since ancient times. Centuries ago, the Ahu A Umi Heiau was built on the dry plateau east of the mountain. The Kaloko-Honokōhau National Historical Park lies on the shore west of Hualālai, over the site of an ancient Hawaiian settlement. Although it

164-423: A few ōhiʻa lehua trees ( Metrosideros polymorpha ) grow along the summit. Many of the collapse craters in particular have vegetation, and a few even have respectably-sized "vertical forests" inside, including several eucalyptus tree groves. The volcano is populated by many birds and animals; the coast in particular attracts many fish and sea-dependent animals, such as the green sea turtle ( Chelonia mydas ) and

205-505: A high threat volcano, with an overall threat score of 109, and ranked it 23rd among United States volcanoes most likely to threaten lives and infrastructure. Since 1971, the Hawaiian Volcano Observatory has maintained a seismic recording station 3 km (1.9 mi) east of Hualālai's summit to monitor the volcano. During this time, not a single earthquake swarm or harmonic tremor , indicative of activity at

246-504: A large underwater slump known as the North Kona slump. An area of about 1,000 km (390 sq mi), the slump consists of an intricate formation of beaches and scarps 2,000 to 4,500 m (6,600 to 14,800 ft) below the waterline. This area was explored more closely in a 2001 joint Japan-United States project to explore the volcano's flanks, utilizing the remotely operated vehicle ROV Kaikō . Data collected showed that

287-401: A sign of this change. Geological mapping of Hualālai indicates that as much as 80% of its surface has been topped by lava flows during the last 5,000 years, entirely composed of shield alkalic basalt . More than half of this is under 3,000 years old, and about 12% is less than 1,000 years old. Between 1700 and 2016, eruptions originated from six vents; four of these lava flows poured into

328-441: A testbed for long term ecological research about Hawaiian moist forest and dry forest biomes , and lies within a mile of the volcano's summit on its northwestern flank. Elevation differs from sea level near the coastal edge to 6,300 ft (1,920 m) near the summit. Median annual rainfall is about 46.7 in (1,186 mm). Plentiful lava flows from the 19th century provide unique niches for vegetative and soil growth in

369-543: A very low level of activity since its last eruption in 1801, and being unusually inactive for the last 2,000 years, Hualālai is still considered active, and is expected to erupt again sometime in the next 100 years. The relative unpreparedness of the residents in the area caused by the lull in activity would worsen an eruption's consequences. The area near Hualālai has been inhabited for centuries by Hawaiian natives , dating back to before recorded history. The coast to its west in particular had several royal complexes. The volcano

410-719: Is a moku or district on the Big Island of Hawaiʻi in the State of Hawaii, known for its Kona coffee and the Ironman World Championship Triathlon. In the administration of Hawaiʻi County , the moku of Kona is divided into North Kona District ( Kona ‘Akau ) and South Kona District ( Kona Hema ). "Kona" sometimes refers to its largest town, Kailua-Kona . Other towns in Kona include Kealakekua , Keauhou , Holualoa , Hōnaunau and Honalo . In

451-430: Is also important ecologically, is home to many rare species and several nature reserves near the summit, and is a popular hiking attraction. Today the coast near Hualālai is dotted by vacation resorts, some built on historic flows, and a National Historical Park . Hualālai stands at 8,271 ft (2,521 m) with a prominence of 3,071 ft (936 m). It is the westernmost of the five major volcanoes that form

492-473: Is an active volcano on the island of Hawaiʻi in the Hawaiian Islands . It is the westernmost, third-youngest and the third-most active of the five volcanoes that form the island of Hawaiʻi, following Kīlauea and the much larger Mauna Loa . Its peak stands 8,271 feet (2,521 m) above sea level. Hualālai is estimated to have risen above sea level about 300,000 years ago. Despite maintaining

533-453: Is called kekaha ʻaʻole wai (lands without water), the rugged volcanic terrain attracted much sea life, making it an appealing place to settle. There are two main attractions within the park: the Kaloko fishpond, an area of loko kuapa (rockwall fishponds) constructed of interlocking rocks across a natural embayment on the coast, and Honokōhau, a former extensive settlement on the south side of

574-430: Is listed as threat level 4. For comparison, almost all of Kīlauea and Mauna Loa is listed as threat levels 1 through 3. The volcano's flanks do not pose a lower threat to the population than the area near the rift zones because the distance is short and the slopes are steep; lava poses as much of a threat as it does near its source. The 2018 U.S. Geological Survey National Volcanic Threat Assessment classified Hualālai as

615-445: Is now located, 11 km (6.8 mi) north of Kailua-Kona. The eruption at Hualālai is believed to have been concurrent with an eruption at the nearby Mauna Loa . It is theorized that in the near past, Hualālai has been active around the same time as both Mauna Loa and Kilauea, although precise dating is impossible. A severe earthquake swarm shook the volcano in 1929, lasting about a month. This caused $ 100,000 worth of damage to

656-480: Is only 50% silica). Geologists hypothesize that Puʻu Waʻawaʻa originally formed during a pumice eruption a little over 100,000 years ago, and has continued to build since then, with at least three distinct trachyte flows recognized. The eruptions, although partially covered by flows from Hualālai and Mauna Loa, have built a distinctive structure known as the Puʻu Anahulu ridge. Hualālai's westward-facing flank forms

697-580: Is the home of the Ironman World Championship Triathlon, which is held each year in October in Kailua-Kona . The Kealakekua Bay State Historical Park marks the place where Captain James Cook was killed in 1779. Puʻuhonua o Hōnaunau National Historical Park and Honokohau Settlement and Kaloko-Honokohau National Historical Park are in Kona. The volcanic slopes of Hualālai and Mauna Loa in

738-542: The 2011 Sendai earthquake . The Hawaii Belt Road traverses the western slopes with an upper route called the Mamalahoa Highway and lower route named for Queen Kaʻahumanu . Much of the Kona coffee crop grows on Hualālai's western slope near the town of Holualoa . The family of early coffee merchant Henry Nicholas Greenwell owned a large ranch on the western side of the volcano. The road from Kailua-Kona up

779-571: The Hawaiian language , kona means leeward or dry side of the island, as opposed to ko‘olau which means windward or the wet side of the island. In the times of Ancient Hawaiʻi , Kona was the name of the leeward district on each major island. In Hawai‘i, the Pacific anticyclone provides moist prevailing northeasterly winds to the Hawaiian islands, resulting in rain when the winds contact

820-477: The Kona district ($ 1.2 million as of 2010), and two earthquakes with magnitudes of 5.5 and 6.5 were felt as far away as Honolulu . This was probably caused by magma movement near the surface, but there was no surface activity or eruption. The 2006 Kiholo Bay earthquake , with epicenter just to the north in Kiholo Bay near Māhukona , caused much damage in the area. Hualālai is expected to erupt again in

861-464: The black-winged stilt ( Himantopus himantopus ). Hualālai averages 18.27 in (46 cm) of rainfall per year. The summit gets more rain than the coast and is typically obscured in heavy cloud cover and vog . Several ecological reserves lie on the flanks of Hualālai. The Puʻu Waʻa Waʻa forest sanctuary was established in 1992 (along with the Laupahoehoe sister reserve on Mauna Kea) as

902-418: The island of Hawaiʻi . Being in the post-shield stage of development, Hualālai is overall much rougher in shape and structure than the more youthful Mauna Loa and Kīlauea . Hualālai's structure is denoted by three rift zones : a well-developed one approximately 50° to the northwest, a moderately developed one to the southeast, and a poorly developed one trending northward about 3 mi (5 km) east of

943-400: The westernization of Hawaii. It was here that Kamehameha I rested after his eight-year campaign to unite the Hawaiian isles. His death in 1819 triggered social chaos. Mokuaikaua Church , built for missionaries in 1837 of lava rock and crushed coral, still stands today. Huliheʻe Palace , where many of Hawaii's last kings spent their time, has been maintained as a museum since 1927. Today,

984-516: The Kona district provide an ideal microclimate for growing coffee . Kona coffee is considered one of the premium specialty coffees of the world. Kona is the home of one of the main bases of the international Christian mission organization YWAM , and the University of the Nations , first founded there. Hual%C4%81lai Hualālai (pronounced [huwəˈlaːlɐi] in Hawaiian )

1025-678: The coast west of Hualālai is a popular location for vacation resorts, since the rain shadow of the mountain causes many sunny days. The first, Kona Village resort , was built in 1961. Since then the Four Seasons Resort and the Kūkiʻo golf course and vacation home complex have also been built on the 1800 flow. Both the Kona Village Resort and the Four Seasons Resort were damaged by the tsunami generated by

1066-450: The exposed lava flows and tephra erupted by Hualālai volcano during the last 112,000 years into 419 rock units of eight chronostratigraphic age groups. These are summarized in the table below: Hualālai last erupted in 1800–1801. This eruption produced very fluid alkalic basalt lava flows that entered the ocean off the western tip of Hawaiʻi island. Although five vents were active at the time, only two produced flows that eventually reached

1107-509: The gods, the flow was finally stopped when Kamehameha I threw a lock of his own hair into the fire. The Ka'ūpūlehu flow is also known for the particularly large quantity of mafic and ultramafic xenoliths that came up with it. The other major outflow from the event reached the sea south of Kiholo Bay , destroying the village of Kaʻūpūlehu . This 1801 flow, known as the Huʻehuʻe flow, formed Keahole Point where Kona International Airport

1148-428: The growth of homes, businesses, and resorts on its flanks. The most recent major activity at the volcano was in 1929, when an intense earthquake swarm rocked it, most likely caused by magmatic action near its peak. Although it has been relatively placid in the recent past, Hualālai is still potentially active, and is expected to erupt again in the next 100 years. The United States Geological Survey (USGS) has divided

1189-504: The lava flows there originated in shallow water 500 to 1,000 m (1,600 to 3,300 ft) deep, and that unlike similar slumps at other volcanoes, the slump at Hualālai formed gradually. Hualālai is a known source for xenoliths , rock from the Earth's mantle that have been brought up in lava flows. Many prehistoric deposits, as well as those from the 1801 event , contain xenoliths of large size and abundant quantity. Lava attributed to

1230-479: The near future, as a 200- to 300-year estimated pause in activity is coming to an end. This presents a distinct hazard to the communities around it; for example, in the event of an eruption similar to the 1801 event, Kailua-Kona, which is 15 mi (24 km) from the volcano's summit, could be covered completely in a matter of hours. According to the USGS lava-flow hazard zones , on a scale of 1 to 9, all of Hualālai

1271-507: The ocean. The total output volume of the flow is estimated at over 300,000,000 m (0.072 cu mi). One volcanic vent, situated high on the slope, produced a large ʻaʻā flow, dubbed the Kaʻūpūlehu flow , that reached the ocean as two distinct lobes. On its way down, it overran a village and a valuable 3 mi (5 km) fishing pond. There is a local legend that after the failure of several offerings of animals and other items to

1312-471: The park. "Outside the (royal) enclosure, by the edge of the sea, was a spring called Ki'ope ... It was a gathering place for those who went swimming and a place where the surf rolled in and dashed on land when it was rough. It was deep enough there for boats to land when the tide was high". —  John Papa Īʻī , court attendant of Kamehameha II . Kamakahonu , Holualoa Bay , and Keauhou Bay were favored retreats of Hawaiian royalty long before

1353-676: The region. The southern section of the reserve, closest to the summit, has been split into a bird sanctuary . The Honuaula forest reserve on the southwestern flank of the volcano at 19°30′25″N 155°54′41″W  /  19.50694°N 155.91139°W  / 19.50694; -155.91139  ( Honuaula State Forest ) , preserves an extensive koa ( Acacia koa ) forest stand, with smaller Naio ( Myoporum sandwicense ) and Māmane ( Sophora chrysophylla ) trees and an undergrowth of ʻĀkala ( Rubus hawaiensis ) and various ferns . The reserve measures 655 acres (265 ha) and protects an ecosystem that has since been largely deforested in

1394-409: The sea to the west coast. Hualālai is the third most active volcano on the island of Hawaiʻi, behind Kīlauea and Mauna Loa. Although the two larger volcanos have each erupted over 150 times in the last 1,000 years, Hualālai has done so only thrice. Activity seems to recur at the volcano every 200 to 300 years. A recent calm period, with almost no earthquake or magmatic activity at Hualālai, has seen

1435-630: The slopes of Hualālai is named for Frank "Palani" Greenwell. Hawaii Route 200 known as the Saddle Road, crosses the plateau north of Hualālai, where the Pohakuloa Training Area provides a remote training ground for the United States Army and United States Marine Corps . Although some of Hualālai is bare volcanic rock, most of it is covered by some form of vegetation. Bushes, ferns, and grass are common, and even

1476-403: The summit at 19°46′15″N 155°49′56″W  /  19.77083°N 155.83222°W  / 19.77083; -155.83222  ( Puu Waa Waa ) . The cone is constructed of trachyte , a type of volcanic lava not found on other volcanoes on the island. Trachyte flows move more slowly than the typically "runny" Hawaiian lavas due to its high (over 62%) silica composition (typical basalt

1517-409: The summit. Over 100 cinder and spatter cones are arranged along these rift zones. Hualālai has no summit caldera , although there is a collapse crater about 0.3 mi (0.48 km) across atop a small lava shield . Much of the southern slope (above the modern town of Kailua-Kona ) consists of lava flows covered by a layer of volcanic ash from 10 to 100 cm (4 to 39 in) thick. Of

1599-518: The volcano, has occurred. Hualālai is also monitored by several other instruments, including one continuous GPS instrument and several instruments on the flanks of adjacent volcanoes. In addition, the Hawaiian Volcano Observatory uses GPS to measure slight changes in tilt and slope of Hualālai, indicative of magmatic movement. Although Hualālai does experience several magnitude-4 earthquakes per year, these are attributed to

1640-443: The volcanoes on the island, it is the third-tallest, third-youngest, third-most active, and second-smallest, making up just 7% of the island. A major subfeature of Hualālai is Puʻu Waʻawaʻa , Hawaiian for "many-furrowed hill", a volcanic cone standing 372 m (1,220 ft) tall and measuring over 1.6 km (1 mi) in diameter. It extends for 9 km (6 mi), and has a prominence of 275 m (902 ft), north of

1681-414: The windward landmass of the islands – the winds subsequently lose their moisture and travel on to the leeward (or kona ) side of the island. When this pattern reverses, it can produce a Kona storm from the west. Kona has cognates with the same meaning in other Polynesian languages . In Tongan, the equivalent cognate would be tonga ; for windward, the associated cognate would be tokelau . Kona
