It is believed to have breached sea level more than 500,000 years ago [1] and to have last erupted 120,000 years ago. Kohala is 606 km 2 (234 sq mi) in area and 14,000 km 3 (3,400 cu mi) in volume, and thus constitutes just under 6% of the island of Hawaii. [1]
This is a list of volcanic eruptions from Kīlauea, an active shield volcano in the Hawaiian Islands that is currently erupting. These eruptions have taken place from pit craters and the main caldera, as well as parasitic cones and fissures along the East and Southwest rift zones.
(Ma = million years) Map of the Hawaiian Islands and some of the Emperor seamounts showing progression in selected erupted lava ages along the chain (Ma = million years) The Hawaiian–Emperor seamount chain is a series of volcanoes and seamounts extending about 6,200 km (3,900 mi) across the Pacific Ocean .
The eruption formed a new vent, covered a large area of land with lava, and enlarged the island. The eruption started as a fissure between two pit craters, ʻĀloʻi and ʻAlae, where the Mauna Ulu shield eventually formed. Both pāhoehoe and ʻaʻā lava erupted from the volcano. Fountains of lava surged as much as 540 meters (1772 ft) into ...
Lava bed after eruption, photograph by Henry L. Chase, 1868. Kīlauea was the most affected by the lateral displacement associated with the earthquake, as it did not have another major eruption until 1919. [3] It also disrupted the magma system beneath Mauna Loa, as is shown both in reduced lava volumes and an abrupt change in the lava ...
When did Haleakalā last erupt? Haleakalā is considered a dormant volcano. Its most recent eruption was likely between 1480 and 1600, according to the U.S. Geological Survey, which continues to ...
La Garita Caldera erupts in the Wheeler Geologic Area, Central Colorado volcanic field, Colorado, USA, eruption several VEI 8 events (Possibly as high as a VEI 9), 5,000 cubic kilometers (1,200 cu mi) of Fish Canyon Tuff was blasted out in a single, major eruption about 27.8 million years ago.
