[22] What is known is that the summit caldera likely formed over several centuries, with its construction estimated to have begun about 500 years ago,[28] and its present form was finalized by a particularly powerful eruption in 1790. Kilauea is one of the most accessible volcanoes in the world. Gas emissions and seismic activity at the summit remain elevated. The relative location of the various vents are marked, and a red, glowing lava flow can just be seen in the north-east of the image. [17], Kīlauea lacks a topographical prominence, appearing only as a bulge on the southeastern flank of the nearby Mauna Loa; because of this, both native Hawaiians and early geologists considered it an active satellite of its more massive neighbor. [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. Tectonic extension along both rift zones is causing Kīlauea's bulk to slowly slide seaward off its southern flank at a rate of about 6 to 10 cm (2 to 4 in) per year, centered on a basal décollement fault 7 to 9 km (4 to 6 mi) beneath the volcano's surface. The eruptions of 680, 1050, 1490, 1500, 1610, 1868 and four eruptions in 1961 have a VEI of 1. [42] At the time, Mauna Ulu was the longest flank eruption of any Hawaiian volcano in recorded history. [88], Kīlauea's northern lowland wet-forest ecosystem is partially protected by the Puna Forest Reserve and the Kahauale`a Natural Area Reserve. [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. The eruption of 1790 has a VEI of 4.

During the 2018 lower Puna eruption, two dozen lava vents erupted downrift from the summit in Puna. Events last anywhere between days and years, and occur at a number of different sites. Shield-type volcanoes are considered as the largest volcanoes on earth. [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. [14] The prevailing, though not completely settled, view is that the hotspot has been largely stationary within the planet's mantle for much, if not all of the Cenozoic Era. 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. [34] This date is similar to that of the oldest dated extant lava flow, a southwestern rift zone flow with an uncorrected radiocarbon dating of approximately 4650 BC. The eruption continued and formed numerous eruption columns up to and beyond 9 km (6 mi) in height, before slowly petering down and ending by May 28. It is the second-youngest product of the Hawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain. Smithsonian Institution. This type of lava is the dominant extrusive during the shield building (the main stage) of hawaiian volcanism and is the dominant basalt type erupted on Earth. In fact, the summit of Kīlauea lies on a curving line of volcanoes that includes Mauna Kea and Kohala and excludes Mauna Loa. Eruptions in the East Rift Zone of Kilauea volcano began in early May, 2018. Evidence suggests the existence of an active eruptive center at this time, termed the Powers Caldera, whose fractures and faults lie 2 km (1 mi) outside the modern caldera. However, research over the past few decades shows clearly that Kīlauea has its own magma-plumbing system, extending to the surface from more than 60 km deep in the earth. Layers of carbonized organic material at the bottom of Kīlauea ash deposits are evidence of the many times the volcano has wrought destruction on its own ecosystem and that of its neighbor Mauna Loa, and parts of the volcano present a dichotomy between pristine montane forest and recently buried volcanic "deserts" yet to be recolonized. [37] The eruption lasted for 26 days and produced an estimated 205 to 265 million cubic meters of lava;[23] the light created by the event was so intense that one could reportedly read a newspaper in Hilo at night, 30 km (19 mi) away. On May 3, 2018, new fissures formed, and lava began erupting in lower Puna after a 5.0 earthquake earlier in the day, causing evacuations of the Leilani Estates and Lanipuna Gardens subdivisions.
