Haleakalā As Seen From Big Island, Hawaii
Haleakalā (; Hawaiian: ), or the East Maui Volcano, is a massive, active shield volcano that forms more than 75% of the Hawaiian Island of Maui. The western 25% of the island is formed by another volcano, Mauna Kahalawai, also referred to as the West Maui Mountains. The tallest peak of Haleakalā ("house of the sun"), at , is Puu Ulaula (Red Hill). From the summit one looks down into a massive depression some across, wide, and nearly deep. The surrounding walls are steep and the interior mostly barren-looking with a scattering of volcanic cones. History Early Hawaiians applied the name ''Haleakalā'' ("house of the sun") to the general mountain. Haleakalā is also the name of a peak on the southwestern edge of Kaupō Gap. In Hawaiian folklore, the depression (crater) at the summit of Haleakalā was home to the grandmother of the demigod Māui. According to the legend, Māui's grandmother helped him capture the sun and force it to slow its journey across the sky in order ...

La Perouse Bay
Keoneōio Bay is located south of the town of Wailea, Hawaii at the end of Mākena Alanui Road (State Highway 31) at . The bay's Hawaiian name is Keoneōio. It was later named for the French explorer Captain Jean-François de Galaup, comte de La Pérouse. But has been referred to the French explorer. In 1786, La Pérouse surveyed and mapped the prominent embayment near the southern cape of Maui opposite the island of Kahoolawe. The bay is the site of Maui's most recent volcanic activity, about 500 years ago. The rounded peninsula that dominates the northern half of the bay and extends up the coast a short distance was formed about 900,000 years ago by an eruption of basaltic lava that originated in the southernmost landward expression of the Haleakalā Southwest Rift Zone. A small string of cinder cones extending inland to the northeast marks the axis of the rift zone. Keoneʻōʻio lies directly south of the Ahihi-Kinau Natural Area Reserve. Fishing is prohibited within the res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mauna Loa
Mauna Loa (, ; ) is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaii in the Pacific Ocean. Mauna Loa is Earth's largest active volcano by both mass and volume. It was historically considered to be the largest volcano on Earth until the submarine mountain Tamu Massif was discovered to be larger. Mauna Loa is a shield volcano with relatively gentle slopes, and a volume estimated at , although its peak is about lower than that of its neighbor, Mauna Kea. Lava eruptions from Mauna Loa are silica-poor and very fluid, and tend to be non-explosive. Mauna Loa has likely been erupting for at least 700,000 years, and may have emerged above sea level about 400,000 years ago. Some dated rocks are 470,000 years old. The volcano's magma comes from the Hawaii hotspot, which has been responsible for the creation of the Hawaiian Island chain over tens of millions of years. The slow drift of the Pacific Plate will eventually carry Mauna Lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Flow Hazard Zones
Lava Flow Hazard Zones are areas designated by the United States Geological Survey for the Island of Hawaii and Maui in the United States. First prepared in 1974 by Donal Mullineaux and Donald Peterson of the USGS and revised in 1992 for the Island of Hawaii, the maps outline the qualitative hazard posed by lava flows based on the history of lava flow activity on each of the five volcanoes that form the Island of Hawaii and Haleakalā volcano on the island of Maui. Zone 1 represents the areas that are most hazardous and Zone 9 the least hazardous. Elsewhere in the world, areas around the town of Grindavik have been declared lava-flow hazard zones, and partially damaged by lava flows. USGS Lava Hazard Zone definitions The lava flow hazard zones are based on location of eruptive vents, past lava coverage, and topography. *Zone 1 - Includes summits and rift zones of Kilauea and Mauna Loa Mauna Loa (, ; ) is one of five volcanoes that form the Island of Hawaii in the U.S. st ...

Hawaii (island)
Hawaii is the List of islands of the United States by area, largest island in the United States, located in the Hawaii, state of Hawaii, the southernmost state in the union. It is the southeasternmost of the Hawaiian Islands, a chain of volcanic islands in the Pacific Ocean, North Pacific Ocean. With an area of , it has 63% of the Hawaiian archipelago's combined landmass. However, it has only 13% of the archipelago's population. The island of Hawaii is the third largest island in Polynesia, behind the North Island, North and South Islands of New Zealand. The island is often referred to as the Island of Hawaii or Hawaii Island to distinguish it from the state. It is also referred to as The Big Island, due to its size relative to the other islands. In Hawaiian language, Hawaiian, the island is sometimes called ''Moku o Keawe''. The word ''keawe'' has several meanings. One definition, "southern cross", is said to be the name of an ancient chief. Another definition is "the bearer". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maui Lava Hazard Map
Maui (; Hawaiian: ) is the second largest island in the Hawaiian archipelago, at 727.2 square miles (1,883 km2). It is the 17th-largest in the United States. Maui is one of Maui County's five islands, along with Molokai, Lānai, Kahoolawe, and Molokini. In 2020, Maui had a population of 168,307, the third-highest of the Hawaiian Islands, behind Oahu and Hawaii Island. Kahului is the largest census-designated place (CDP) on the island, with a 2020 population of 28,219. It is Maui's commercial and financial hub. Wailuku is the county seat and was the third-largest CDP . Other significant populated areas include Kīhei (including Wailea and Makena in the Kihei Town CDP), Lāhainā (including Kāanapali and Kapalua in the Lāhainā Town CDP), and Upcountry Maui (including Makawao, Pukalani, Kula, and Ulupalakua), although Lāhainā was mostly destroyed by fire in 2023. Once part of Maui Nui, Maui is dominated by two volcanic features: Haleakalā in the southeast, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption. An eruption that ejects large volumes of magma over a short period of time can cause significant detriment to the structural integrity of such a chamber, greatly diminishing its capacity to support its own roof and any substrate or rock resting above. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur over the course of a century, the formation of a caldera is a rare event, occurring only a few times within a given window of 100 years. Only eight caldera-forming collapses are known to have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rift Zone
A rift zone is a feature of some volcanoes, especially shield volcanoes, in which a set of linear cracks (or rifts) develops in a volcanic edifice, typically forming into two or three well-defined regions along the flanks of the vent. Believed to be primarily caused by internal and gravitational stresses generated by magma emplacement within and across various regions of the volcano, rift zones allow the intrusion of magmatic dykes into the slopes of the volcano itself. The addition of these magmatic materials usually contributes to the further rifting of the slope, in addition to generating fissure eruptions from those dykes that reach the surface. It is the grouping of these fissures, and the dykes that feed them, that serves to delineate where and whether a rift zone is to be defined. The accumulated lava of repeated eruptions from rift zones along with the endogenous growth created by magma intrusions causes these volcanoes to have an elongated shape. Perhaps the best ...
