More reliable paleomagnetic dating, limited to rocks dating from after Kīlauea's emergence from the sea, has suggested ages of around 50,000 years. Avoid the stress of planning out all the details with this guided tour that includes round-trip transport, lunch, snacks, and bottled water for your convenience. She is said to reside in Halemaʻumaʻu crater, a persistently active pit within the summit caldera. Although explosive activity still occurs at the volcano, it is not as intense as it once was, and the volcano would become much more dangerous to the general public if it returned to its old phase of activity once more. It was the 11th National Park in the United States, and the first in a Territory;[107] a few weeks later, the National Park Service Organic Act was signed into law, creating the National Park Service and tasking it with running the expanding system. Its most recent eruption began on December 20, 2020. Following endorsements from John Muir, Henry Cabot Lodge, and former President Theodore Roosevelt (in opposition to local ranchers) and several legislative attempts introduced by delegate Jonah Kūhiō Kalaniana'ole, House Resolution 9525 was signed into law by Woodrow Wilson on August 1, 1916. When Kīlauea lay dormant between 1934 and 1952, Mauna Loa became active, and when the latter remained quiet from 1952 to 1974, the reverse was true. [16], Kīlauea is one of five subaerial volcanoes that make up the island of Hawaiʻi, created by the Hawaii hotspot. [22], Geologists have dated and documented dozens of major eruptions over the volcano's long history, bridging the long gap between Kīlauea's oldest known rock and only extremely recent written records and historical observation. Exploring Hawaii’s Big Island can be a big undertaking, but it doesn’t have to be. In Hawaii, this cursed year is going out with even more horror. [54][55], A seemingly related 6.9 magnitude earthquake occurred on May 4. [36], Kīlauea erupted in 1823 and 1832, but the first major eruption since the 1790 event occurred in 1840, when its eastern rift zone became the site of a large, effusive Hawaiian eruption over 35 km (22 mi) of its length, unusually long even for a rift eruption. [57][58], By May 21, two lava flows had reached the Pacific Ocean, creating thick clouds of laze (a toxic lava and haze cloud), which is made up of hydrochloric acid and glass particles. It had the longest duration of any observed eruption at this volcano. There are thought to be many more as-yet-undocumented species within the forest. [53] The Hawaiian Volcano Observatory warned that the lowering of the lava lake increased the potential for phreatic (steam) explosions at the summit caused by interaction of magma with the underground water table, similar to the explosions that occurred at Halemaʻumaʻu in 1924. Kilauea is one if not the most active volcano in the world Kilauea’s longest period of inactivity is recorded at 18 years between 1934 and 1952, making many volcanologists rank it as the world's most active volcano. [40] Eruptions occurred soon after in 1954, 1955, and 1959, capped by a large event in 1960, when fissure-based phreatic eruption and earthquake activity gave way to a massive ʻaʻā flow that overran multiple evacuated communities and resorts; the resulting summit deflation eventually caused the ever-active Halemaʻumaʻu to collapse even further. Between 1986 and 1991, the connection between Chain of Craters Road and Hawaii Route 130 was cut, and the community of Kapa’ahu, the village of Kalapana, and the subdivisions of Kālapana Gardens and Royal Gardens were lost to the lava. [72] Within a month, the water lake would be replaced by a lava lake during a new eruption. Early on, fountains of lava burst out as much as 540 meters (1772 ft) high. Kīlauea erupted nearly continuously from 1983 to 2018, causing considerable property damage, including the destruction of the towns of Kalapana and Kaimū along with the renowned black sand beach, in 1990. In fact, the summit of Kīlauea lies on a curving line of volcanoes that includes Mauna Kea and Kohala and excludes Mauna Loa. Hawaiians used the word Kīlauea only for the summit caldera, but earth scientists and, over time, popular usage have extended the name to include the entire volcano. Both pāhoehoe and ʻaʻā lava erupted from the volcano. [85] The Kīlauea coast also hosts three of the nine known critically endangered hawksbill sea turtle (Eretmochelys imbricata) nesting sites on the island. [38], Activity in 1921–1923 followed. [87] The deposited tephra particulates make the local soil very permeable. An example is Mt. Kīlauea is an active shield volcano in the Hawaiian Islands. Thurston, who owned the Honolulu Advertiser newspaper, printed editorials in favor of the idea; by 1911 Governor Walter F. Frear had proposed a draft bill to create "Kilauea National Park". Lava erupted in Leilani Estates after the Kilauea Volcano exploded in Hawaii, June 5, 2018 Credit: reuters. Hawaiians used the word Kīlauea only for the summit caldera, but earth scientists and, over time, popular usage have extended the name to include the entire volcano. He collated the first written account of the volcano and observed many of its features, establishing a premise for future explorations of the volcano.[99]. On March 19, 2008, following several months of increased sulfur dioxide emissions and seismic tremor, a new vent opened at Halemaʻumaʻu at Kilauea's summit in an explosive eruption. [4] By the following morning, emergency officials reported that the eruption had stabilized and that two of the three vents remained active and continued to fill the floor of Halemaʻumaʻu with lava. Historically, the five volcanoes on the island were considered sacred by the Hawaiian people, and in Hawaiian mythology Kīlauea's Halemaʻumaʻu served as the body and home of Pele, goddess of fire, lightning, wind, and volcanoes. The vent produced vigorous lava fountains that quickly built up into the Puʻu ʻŌʻō cone, sending lava flows down the volcano's slope. Explosive activity began on May 10 of that year, blowing rock chunks weighing as much as 45 kg (99 lb) 60 m (197 ft) out, and smaller fragments weighing about 9 kg (20 lb) out as far as 270 m (886 ft), and, after a brief reprieve, intensified through a major blast on May 18, when an enormous explosive event caused the eruption's only fatality. The eruption created a new vent, covered a large area of land with lava, and added new land to the island. [5] Continued explosive activity at the summit caused a months-long closure of the Kīlauea section of Hawaii Volcanoes National Park. [83], Much of Kīlauea's southern ecosystem lies within the Hawaiʻi Volcanoes National Park, where a’e ferns, ʻōhiʻa trees (Metrosideros polymorpha), and hapu’u of the genus Cibotium are common. 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. Plant life in the region is practically nonexistent.

The southwestern rift zone also lacks a well-defined ridge line or a large number of pit craters, evidence that it is also geologically less active than the eastern rift zone. [47], In addition to the nearly continuous activity at Puʻu ʻOʻo and other vents on the east rift zone, a separate eruption began at Kilauea's summit in March 2008. Kīlauea is the youngest and southeastern most volcano on the Island of Hawai‘i. Kīlauea's high state of activity has a major impact on its mountainside ecology, where plant growth is often interrupted by fresh tephra and drifting volcanic sulfur dioxide, producing acid rains particularly in a barren area south of its southwestern rift zone known as the Kaʻū Desert. The Kilauea volcano on Hawaii's Big Island has erupted, the U.S. Geological Survey said, about an hour before an earthquake struck the area. Beginning in February 2010, a lava pond was visible at the bottom of the crater almost continuously through the beginning of May 2018. Kamapuaʻa, hard-pressed by Pele's ability to make lava spout from the ground at will, covered the feature, a favorite residence of the goddess, with fern fronds. [33] Historical lava flows from the volcano are generally recovered by scientists in one of three ways. It is just one of the five volcanoes that make up Hawaii. [22], The length and origin of these eruptions have also varied. [20], Following the pattern of Hawaiian volcano formation, Kīlauea started as a submarine volcano, gradually building itself up through underwater eruptions of alkali basalt lava before emerging from the sea with a series of explosive eruptions[21] about 50,000 to 100,000 years ago. Kīlauea is the home of Pele, the Hawaiian volcano goddess. [41], From 1960 on, eruptive events occurred frequently until August 2018. Kilauea is an active volcano in the Hawaiian Islands.It is a shield volcano.The volcano is 1,277 meters high. In late July 2019, a water lake appeared on the bottom of Halemaʻumaʻu for the first time in over 200 years,[70] as water from the rebounding water table began entering the crater. The oldest exposed lavas date back 2,800 years. [93] Kīlauea itself means "spewing" or "much spreading" in Hawaiian, referencing its high state of activity,[17] and in Hawaiian mythology, Kīlauea is the body of the deity Pele, goddess of fire, lightning, wind, and volcanoes. This unexpected communication is evidence of crustal-level interactions between Mauna Loa and Kīlauea, even though these two volcanoes are thought to be fairly independent of each other.

From 1983 to 2018 eruptive activity was nearly continuous along the volcano's East Rift Zone. [31] Kīlauea has some interactions with Mauna Loa, its larger neighbor and only other recently active volcano on the island; interspersed lava flows and ash deposits belonging to its neighbor have been found on its flanks, and some of Mauna Loa's flows are, in turn, blanketed in Kīlauea tephra. HVO field crews—equipped with specialized safety gear and PPE—monitor the current eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission. Hawaiians associated elements of their natural environment with particular deities. Vigorous eruptive lava fountains in lower Puna sent destructive rivers of molten rock into the ocean in three places. [8] On December 5, 2018, after 90 days of inactivity from the volcano, the eruption that began in 1983 was declared to have ended. [23] The bulk of Kīlauea consists of solidified lava flows, intermittent with scattered volcanic ash and tephra sourced from relatively lower-volume explosive eruptions. [71] However, during the December 2020 eruption, this scenario did not occur, as the eruption was non-explosive in nature, with three vents feeding magma into the lake and boiling off the water. [56] By May 9, 27 houses had been destroyed in Leilani Estates. Multiple continuous lava fountains between 15 and 30 m (50 and 100 ft) persisted, and the eruption lasted 136 days. [93] Early settlements had a major impact on the local ecosystem, and caused many extinctions, particularly amongst bird species, as well as introducing foreign plants and animals and increasing erosion rates. The longest major eruption observed at Kīlauea in modern history occurred from January 1983 to September 2018. Ever since Hawaii's Kilauea stopped erupting in August 2018, ceasing activity for the first time in 35 years, scientists have been wondering about the volcano's future. [76], In 2018, the United States Geological Survey National Volcanic Threat Assessment gave Kīlauea an overall threat score of 263, and ranked it first among volcanoes in the United States most likely to threaten lives and infrastructure. Activity there was nearly continuous for much of the 19th century, and after a reprieve between 1894 and 1907, continued onwards until 1924. William Ellis, saw the summit in 1823. [60][61] By June 4, with the lava having crossed through Kapoho and entered the ocean, the confirmed number of houses lost had reached 159. [23] The next major eruption occurred in 1924. On May 17, 2018, the volcano explosively erupted at the summit in Halemaʻumaʻu, throwing ash 30,000 feet (9,144 m) into the air. At the summit, a vent within Halema‘uma‘u hosted an active lava pond and vigorous gas plume from 2008 to 2018. The presence of the new water lake in Halemaʻumaʻu means that Kīlauea's next summit eruption could be explosive, if magma rises rapidly to the surface. [33], The oldest well-studied eruptive product from Kīlauea is the Uwēkahuna Ash Member, the product of explosive eruptions between 2,800 and 2,100 years ago. Its first recorded eruptions were in 1823.Its most recent eruption was March 3 2018. Since 1952, Kīlauea has erupted 34 times. As of December 2020[update], it is the twelfth-longest duration volcanic eruption on Earth since 1750. In historical times, Kilauea has been Hawaii’s most active volcano. [98] The first non-native to observe Kīlauea in detail was William Ellis, an English missionary who in 1823 spent more than two weeks trekking across the volcano. Whereas this type of seismicity was observed on average once every few weeks following the 2018 eruption, rates have increased to over a dozen in the past several days. There have been five historical eruptions at the volcano's relatively quiet southwestern rift zone, and 24 along its more active eastern rift zone, mostly along its upper section. Located along the southeastern shore of the island, the volcano is between 210,000 and 280,000 years old and emerged above sea level about 100,000 years ago. [23] It is unknown if the caldera was always there or if it is a relatively recent feature, and it is possible that it has come and gone throughout Kīlauea's eruptive history. [22] Since 1918, Kīlauea's only prolonged period of rest was an 18-year pause between 1934 and 1952. The eruption was preceded by earthquake swarms centered at Kīlauea Caldera on November 30, 2020 and December 2, 2020, the second of which was interpreted as a small intrusion of magma. [74] By 7:30 a.m. on December 25, 2020, the lava lake had filled in 176 metres (577 ft) of the crater, and the level of the lake was continuing to rise. Volcano, vent in the crust of Earth or another planet or satellite, from which issue eruptions of molten rock, hot rock fragments, and hot gases.A volcanic eruption is an awesome display of Earth’s power. Photo by Jim Griggs, 1985 (U.S. Geological Survey). Its surface makes up an area slightly smaller than the island of Oʻahu. The US Geological Survey's Hawaiian Volcano Observatory reported that three vents were feeding lava into the bottom of Halemaʻumaʻu Crater, boiling off the water lake that had been growing since summer 2019 and replacing it with a lava lake. [82], Kīlauea's bulk affects local climate conditions through the influence of trade winds coming predominantly from the northeast, which, when squeezed upwards by the volcano's height, result in a moister windward side and a comparatively arid leeward flank. This type of volcano can have eruptions accompanied by lahars -- deadly mudflows. Shield volcanoes (like Kilauea) are shaped like a bowl in the middle with long gentle slopes made by basaltic lava flows – this is the most common type of lava on Earth and consists of high amounts of iron and magnesium.
