Scientists have two theories about the formation of the Hawaiian Islands. [76][77] By July 24, 2018, the western boundaries of the lava spill was within 200 yards (180 m) of Isaac Hale Beach Park. Un phénomène fascinant mais dangereux pour la santé. [54] On May 27, one of the 11 geothermal wells at the PGV was covered by the advancing lava flow from the Leilani Estates fissures,[55][56] the first time lava had covered a geothermal well,[57] followed by a second well hours later, along with ten more structures in the adjacent Leilani Estates. The active volcano experienced a series of explosive eruptions in 2018 but has since remained "silent" until earlier this month, when it started showing signs of seisimic actvities. [26][27] The Puna Geothermal Venture (PGV), a power station, was shut down on 22 May 2018;[28] the geothermal power plant provided approximately 25% of the Big Island's power, but its shutdown was later stated not to present a risk to power on the island. to Kīlauea’s 2018 lower East Rift Zone eruption and summit collapse involved more than 90 employees from other USGS offices, including Unmanned Aircraft Systems flight crews, and numerous university collaborators and volunteers. [22], On May 3, 2018, after a 5.0 earthquake earlier in the day, steaming ground cracks opened in Leilani Estates and began to spew lava, causing evacuations of the Leilani Estates and Lanipuna Gardens subdivisions. Dalton said he and his family lost their home in Leilani Estates in the 2018 eruption of the Kilauea volcano, an explosion that destroyed hundreds of homes and forced thousands to flee. From May 23, eruptions at the eastern fissures began to weaken considerably, as lava activity moved back up the rift zone; older fissures reopened to release fluid pāhoehoe, which rapidly replaced the output of ʻaʻā, and led to massive pooling of lava over lower Leilani Estates. At the summit, a vent within Halema‘uma‘u hosted an active lava pond and vigorous gas plume from 2008 to 2018. The current Kilauea eruption comes after a three-and-a-half-decade-long eruption that ended more than two years earlier. On the same day, fissures 5, 13, and 15 began to form lava fountains around the Leilani Avenue-Kahukai Street intersection. The deadliest Hawaiian eruption in recent history was in 1790 when 400 people were killed during an eruption of Kilauea. 2018 Eruption and Summit Collapse. The pool of lava in Leilani Estates eventually spilled eastwards into two paths, one short-lived route running southeast parallel to lava channels headed for the ocean, and another travelling northeast, crossing Pohoiki Road over the western boundaries of the Puna Geothermal Venture. As an example: When the eruption started in May, the Steamboat geyser in Yellowstone coincidentally had several rare eruptions at about the same time. It was also fairly certain that, based on past activity, the next eruption would likely occur somewhere on Kilauea’s East Rift Zone. [43] Starting May 23, two CH-53E Super Stallion helicopters were on standby in Hilo in case of sudden evacuation needs. Kilauea's first well-documented eruption occurred in 1823, but evidence shows there have been many explosive eruptions prior to this date. Two hundred residents and their pets were in two Red Cross shelters and hundreds more were staying with family and friends. Kilauea’s epilogue arrived on Dec. 6, when the USGS declared that it was “very unlikely” the 2018 eruption at the rift zone would resume. [72], Temporary repair works were conducted for sections of Highway 11 (near Volcano Village and the entrance to Volcanoes National Park) and Highway 130 (connecting much of lower Puna to the rest of the island), which suffered cracks from seismic activities over the months, and have been subject to restricted use due to the extent of their damage. [83] A proposed ban on future home construction in areas subject to high-risk of volcanic activity was also reported on July 1, 2018 to be in discussion by Hawaii politicians. Several first responders were sickened by sulfur dioxide gas. [25] The Hawaii County Civil Defense Agency reported high levels of toxic sulfur dioxide gas in the area, and Talmadge Magno, the Civil Defense Administrator for Hawaiʻi County, stated that power lines had melted off poles from the heat. In May 2018, Kilauea Volcano sprung a leak. The Kīlauea Volcano on the island of Hawai‘i erupted for 3 months in 2018. Lava started erupting in the Lower East Rift Zone (LERZ) on May 3, and continued through early August. Posted on Oct 7, 2020 in 2018 Kilauea Eruption, Featured, Information and News Releases, Main, News Stories. [14] It was estimated that recovery efforts would cost more than $800 million (2018 USD). There was also a side vent on the volcano’s shoulder, Puʻu ʻŌʻō, erupting lava for 35 years. Thirteen were treated at the hospital, including three who were admitted with unspecified injuries and one in serious condition with a broken thigh bone. One of the more spectacular recent ones was in … Aprilhälfte über den Boden des Halemaʻumaʻu-Kraters zu laufen. Éruption du volcan Kilauea. [47] On May 17, at approximately 4:15 a.m., an explosive eruption occurred at Halemaʻumaʻu, creating a plume of ash 30,000 feet into the air. The Science Behind Hawaii's Surprising 2018 Volcanic Eruption By Laura Geggel - Associate Editor 04 June 2018 Fountaining at fissure 22 has reached as high as 160 feet (50 meters). It was not known how and when power to those communities could be restored. [33] The lava vents formed a northeast/southwest line;[31] officials were concerned about potential damage to a water main in the area. Kilauea's eruption in 2018 is a perfect example of the importance of accurate information in this age of the unfiltered internet. Le Kīlauea ou Kilauea est un volcan des États-Unis situé à Hawa ï, dans le Sud-Est de l'archipel et de l'île du même nom. 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. [7][8] Lava entered the Kapoho Crater and evaporated Green Lake, which had been the largest natural freshwater lake in Hawaiʻi. [25], A 6.9 magnitude earthquake occurred on May 4[29] that the United States Geological Survey said was related to the eruptions. [89] On July 16, a further 23 were injured when a tour boat carrying passengers observing a lava ocean entry was pelted by lava rocks thrown by an intense hydrovolcanic explosion, including a large lava rock that pierced through the boat's roof. Panache de fumée du volcan Kilauea (Hawaï) après le tremblement de terre de magnitude 6,9, le 4 mai 2018 Crédit : U.S. Geological Survey - Licence : CC0. There was also a side vent on the … Im Mai 2018 überschlugen sich die Ereignisse am Kilauea auf Hawaii. [25], The next day, May 4, two homes were reported destroyed in Leilani Estates from three erupting vents. The Eruption occurred in the island of Hawaii from the volcano Kilauea's East Rift Zone on May 3rd, 2018. The first known injury was reported on May 20, 2018: A homeowner was struck with a piece of "lava spatter" and suffered burns and a broken leg. [63], In addition to the draining of Puʻu ʻŌʻō, the protracted release of lava along the Lower East Rift Zone has also led to significant drainage of lava away from Halemaʻumaʻu at Kīlauea, resulting in large scale inward slumping and collapse around the crater and regular earthquakes since May 17, similar in pattern to the crater's slumping during the 1924 event. Last updated: March 2, 2021. Last week, the ongoing Kilauea eruption spawned a tiny addition to the Hawaiian island chain. Photos and media from the eruption that began on December 20, 2020 . HVO greatly appreciates the support provided during this unprecedented event on the Island of Hawaiʻi. With all that magma (lava when it’s underground) draining away from the summit of the volcano, Halemaʻumaʻu Crater fell in, and the larger caldera around it sank hundreds of feet as well, revealing sulfur banks and other features not seen since Mark Twain visited in the 1800s. Due to continued encroachment by lava, the number of destroyed structures was revised upward to 82 on May 25. [9] By June 5, Kapoho Bay had been filled in with lava now forming a point where the bay had been. ʻAhuʻailāʻau's lava fountains rapidly formed a new cinder cone, increasing the volume of pooling lava over the course of the week and feeding the northeastern flow further. [81] Afterward, a small lava lake was maintained within the crater of the ʻAhuʻailāʻau cone for another 3 weeks. Kilauea, a volcano on Hawaii's big island underwent a long, drawn-out eruption over this past summer. On the night of June 4–5, the northeastern flow of lava speedily moved forward and destroyed the subdivision of Vacationland Hawaii. In 2018, the decades-long continuous activity on the East Rift Zone ended, and the summit lava lake drained following an intrusion into, and eruption from, Kīlauea's lower East Rift Zone. Eruptions aren't anything new on Kilauea. June 15, 2018 ; USGS. During July there were almost daily collapses with shaking equivalent to an M5.3 earthquake (see my video archive). 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. Puʻu ʻŌʻō had become a prominent volcanic cone 19 km (12 mi) east of the summit caldera of Kīlauea, since the 1983 eruption's beginning. Latest News. Within the same time frame, the USGS reported that Puʻu ʻŌʻō was venting gases at its highest rate in more than 10 years, though no other noticeable changes had taken place at the vent. [79], Eruption activity at ʻAhuʻailāʻau began to see a downtrend beginning on August 5, 2018, as the intensity of both the lava channel and seismic activity at Halemaʻumaʻu decreased significantly over the course of the following days. [72] The official toll of houses reached 700 on July 9, leaving 3 houses left standing in Kapoho. [52] The area of land covered by the 2018 lava on May 25, 2018 reached 2,223 acres. [64] Explosions or mild earthquakes of similar magnitude became an almost daily cyclical occurrence at the summit, and have also been reported to influence the intensity of lava surges at ʻAhuʻailāʻau. Magma still exists beneath the summit and rift zone. The 2018 eruption at Kīlauea was the largest in the United States since 1980. 15:00 (French time): The latest update I have received from HVO (posted on May 3 rd, 2018 at 10:13 p.m., local time) indicates that the eruption in the Leilani Estates subdivision in the lower East Rift Zone of Kilauea Volcano that began in late afternoon ended by about 6:30 p.m. (local time). Dalton said he and his family lost their home in Leilani Estates in the 2018 eruption of the Kilauea volcano, an explosion that destroyed hundreds of homes and forced thousands to flee. On May 6, Hawaiʻi County Civil Defense reported that 26 houses had been destroyed by lava or fires in Leilani Estates. We’ll explain by starting with some facts about the volcano. In the first two days of May, hundreds of small earthquakes were detected on Kīlauea's East rift zone, leading officials to issue evacuation warnings for some residents of the Puna District. Unlike most volcanoes, the Hawaiian chain sits squarely in the middle of the Pacific plate rather than on a tectonic boundary. [53] The eastern fissures would experience limited resurgences in activity into June and July. The 35-year long eruption of the Kilauea volcano erupted in the Pu’u’ Ō‘ō vent. [16], The Hawaii National Guard stated on May 11, 2018, that they were ready to evacuate up to 2,000 people at a moment's notice, through the use of land convoys and Blackhawk and Chinook helicopters.
