Hawaiʻi Volcanoes National Park
Hawaii Volcanoes National Park is an American national park located in the U.S. state of Hawaii on the island of Hawaii. The park encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's most massive shield volcano. The park provides scientists with insight into the development of the Hawaiian Islands and access for studies of volcanism. For visitors, the park offers dramatic volcanic landscapes, glimpses of rare flora and fauna, and a view into the traditional Hawaiian culture connected to these landscapes. The park was originally established on August 1, 1916, as ''Hawaii National Park'', which was then split into this park and Haleakalā National Park. In recognition of its outstanding natural values, Hawaii Volcanoes National Park was designated as an International Biosphere Reserve in 1980 and a World Heritage Site in 1987. In 2012, the park was depicted on the 14th quarter of the America the Beautiful Quarters series. ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ...

Hawaiian Volcano Observatory
The Hawaiian Volcano Observatory (HVO) is an agency of the U.S. Geological Survey (USGS) and one of five volcano observatories operating under the USGS Volcano Hazards Program. Based in Hilo, Hawaii, the observatory monitors six Hawaiian volcanoes: Kīlauea, Mauna Loa, Kamaʻehuakanaloa (formerly Lōʻihi), Hualālai, Mauna Kea, and Haleakalā, of which, Kīlauea and Mauna Loa are the most active. The observatory has a worldwide reputation as a leader in the study of active volcanism. Due to the relatively non-explosive nature of Kīlauea's volcanic eruptions for many years, scientists have generally been able to study ongoing eruptions in proximity without being in extreme danger. Prior to May 2018, the observatory's offices were located at Uwekahuna Bluff, the highest point on the rim of Kīlauea Caldera. The summit collapse events during the 2018 eruption of Kīlauea damaged those facilities, so the observatory has since been operating from various temporary offices located ...

Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. 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 each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ...

Halemaʻumaʻu Crater2
Halemaumau (''six syllables: HAH-lay-MAH-oo-MAH-oo'') is a pit crater within the much larger Kīlauea Caldera at the summit of Kīlauea volcano on island of Hawaiʻi. The roughly circular crater was x before collapses that roughly doubled the size of the crater after May 3, 2018. Following the collapses of 2018, the bottom of Halemaumau was roughly below the caldera floor. Halemaumau is home to Pele, goddess of fire and volcanoes, according to the traditions of Hawaiian religion. Halemaʻumaʻu means "house of the āmau fern". Halemaumau contained an active lava lake for much of the time before 1924, and was the site of several eruptions during the 20th century. The crater again contained an active lava lake between 2008 and 2018, with the level of the lava usually fluctuating between 20 and 150 meters below Halemaumau's crater floor, though at times the lava lake rose high enough to spill onto crater floor. The lava lake drained away in May 2018 as new volcanic vents o ...

Kalapana, Hawaii
Kalapana is a town and a region in the Puna District on the Island of Hawaii in the Hawaiian Islands. The town was the original location of the Star of the Sea Painted Church. In 1990, lava flows from the Kūpaʻianahā vent of Kīlauea destroyed and partly buried most of the town, as well as Kalapana Gardens and nearby Royal Gardens subdivisions. The lava flow that destroyed Kalapana erupted from the southeast rift zone of Kīlauea. Along with the destruction of Kalapana were those of the nearby town of Kaimū and Kaimū Bay, both of which now lie buried beneath more than 50 feet of lava. The lava flow created a new coastline. In July 2010, lava from Kīlauea continued into the Kalapana region destroying a home that was only 5 years old, leaving 35 homes remaining in the Kalapana Gardens Subdivision. The 2010 lava flow partly covered the 1986–1992 flow field again, while attracting thousands of visitors a day. Access to the village was reestablished and a thriving farmers ma ...

Chain Of Craters Road
Chain of Craters Road is a long winding paved road through the East Rift and coastal area of the Hawaii Volcanoes National Park on the island of Hawaii, in the state of Hawaii, United States. The original road, built in 1928, connected Crater Rim Drive to Makaopuhi Crater. The road was lengthened to reach the tiny town of Kalapana in 1959. As of 2018, the road has had parts covered by lava in 41 of the past 53 years, due to eruptions of Kīlauea volcano. Route description The road has paths and road offshoots that allow access to features such as pit craters, dormant lava flows, plumes from lava tubes and geographic sites that can be accessed by trails from the road. There are also scenic views through tropical rainforests, and the coast. Next to the park's visitor center is the paved Crater Rim Drive around Kilauea caldera, off which a short paved road leads to a viewpoint overlooking Kīlauea, the origin of the 1995 eruption that closed the Chain of Craters Road. The road b ...

Hawaii Belt Road
The Hawaii Belt Road is a modern name for the Māmalahoa Highway and consists of Hawaii state Routes 11, 19, and 190 that encircle the Island of Hawaii. The southern section, between Hilo and Kailua-Kona is numbered as Route 11. The section between Hilo and Waimea is Route 19. Between Waimea and Kailua-Kona, the road is split in two: the original "mauka" route (now Route 190) and a "makai" Route 19, completed in 1975, which serves as access to the Kona and Kohala Coast resorts. In the Hawaiian language, ''mauka'' means "towards the mountain" and ''makai'' means "towards the sea". These terms are commonly used in travel directions. Parts of the southern half of the Hawaii Belt Road were known during the Territorial days as the Kaū Belt Road. The names "Hawaii Belt Road" and "Māmalahoa Highway" refer to the road system that encircles the entire island; many sections are also referenced by local names. History Māmalahoa Highway was named for the royal decree by King Kameham ...
