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 ...

Pahoehoe
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'', w ...

Hydrogen Sulfide
Hydrogen sulfide is a chemical compound with the formula . It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is ''stinkdamp''. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777. The British English spelling of this compound is hydrogen sulphide, a spelling no longer recommended by the Royal Society of Chemistry or the International Union of Pure and Applied Chemistry. Hydrogen sulfide is toxic to humans and most other animals by inhibiting cellular respiration in a manner similar to hydrogen cyanide. When it is inhaled or it or its salts are ingested in high amounts, damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death. Despite this, the ...

2018 Lower Puna Eruption
The 2018 lower Puna eruption was a volcanic event on the island of Hawaiʻi, on Kīlauea volcano's East Rift Zone that began on May 3, 2018. It is related to the larger eruption of Kīlauea that began on January 3, 1983, though some volcanologists and USGS scientists have discussed whether to classify it as a new eruption. Outbreaks of lava fountains up to high, lava flows, and volcanic gas in the Leilani Estates subdivision were preceded by earthquakes and ground deformation that created cracks in the roads. On May 4, a 6.9 magnitude earthquake hit Puna. By May 27, 2018, 24 fissures had erupted lava in and near the Leilani Estates and Lanipuna Gardens subdivisions. The eruption forced the evacuation of approximately two thousand residents. The Puna Geothermal Venture, which provided one-quarter of the island's electricity, was forced to shut down and was later damaged by lava. The fissures had sent lava rivers that buried part of Hawaii Route 137 on May 19, and began flowin ...

Hawaii Route 130
Route 130 is a state highway in Hawaii County, Hawaii, United States. It runs from Route 11 at Ke'aau through the Puna District to Kaimū. __TOC__ Route description Route 130 starts from the intersection of Keaau on Route 11, in the south of Hilo. After a junction with It heads south on the east side of Kīlauea to Pahoa, where Route 132 branches out via Kapoho to Cape Kumukahi with further connection to Route 137, and curves toward the west, ending near Kaimū following a junction with Route 137 itself. History Route 130 used to travel further to the west along the Chain of Craters Road in Hawaii Volcanoes National Park. However, it was truncated to its current terminus due to the lava flows from Puʻu ʻŌʻō Puu Ōō (also spelled Pu‘u‘ō‘ō, and often written Puu Oo, , ) is a volcanic cone on the eastern rift zone of Kīlauea volcano in the Hawaiian Islands. The eruption that created Puu Ōō began on January 3, 1983, and continued nearly c ... ...

Puʻu ʻŌʻō
Puu Ōō (also spelled Pu‘u‘ō‘ō, and often written Puu Oo, , ) is a volcanic cone on the eastern rift zone of Kīlauea volcano in the Hawaiian Islands. The eruption that created Puu Ōō began on January 3, 1983, and continued nearly continuously until April 30, 2018, making it the longest-lived rift-zone eruption of the last two centuries. By January 2005, of magma covered an area of more than and added of land to the southeast coast of Hawaii. The eruption claimed at least 189 buildings and of highways, as well as a church, a store, the Wahaula Visitor Center, and many ancient Hawaiian sites, including the Wahaula heiau. The coastal highway has been closed since 1987, as parts of the road have been buried under lava up to thick. Etymology The hill was initially nicknamed "Puu O" by volcanologists, as its position when marked on a map of the area coincided with an "o" in "Lava flow of 1965". Later, the elders of the village of Kalapana were asked to name the ...

Fault Scarp
A fault scarp is a small step or offset on the ground surface where one side of a fault has moved vertically with respect to the other. It is the topographic expression of faulting attributed to the displacement of the land surface by movement along faults. They are exhibited either by differential movement and subsequent erosion along an old ''inactive'' geologic fault (a sort of old rupture), or by a movement on a recent active fault. Characteristics Fault scarps often contain highly fractured rock of both hard and weak consistency. In many cases, bluffs form from the upthrown block and can be very steep. The height of the scarp formation is equal to the vertical displacement along the fault. Active scarps are usually formed by tectonic displacement, e.g. when an earthquake changes the elevation of the ground and can be caused by any type of fault, including strike-slip faults, whose motion is primarily horizontal. This movement is usually episodic, with the height of the bluf ...

Pauahi (crater)
Pauahi Crater is a volcanic crater measuring long, up to some across, and deep in Hawaii Volcanoes National Park at . It is about from the top of the Big Island of Hawaii's 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 Ri ..., which follows a "chain" that also includes the Hiʻiaka, Puʻu Huluhulu, Kānenuiohamo, Makaopuhi and Nāpau craters. Eruptive history Three historic eruptions have occurred at or near Pauahi Crater. The first was in May 1973 when a fissure opened and erupted briefly on its floor. The second took place in November 1973 and lasted 31 days (November 10 — December 9), but most activity was concentrated during the event's initial 10 hours. The eruption created a set of echelon fissures extending over some from a point just west of ...
