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. They are generally fluid ( VEI -0) Hawaiian eruptions , but more violent eruptions have occurred throughout Kīlauea's eruptive history, with the largest recorded explosive eruption having ...
Between June 6 and 9, 1912, the most spectacular Alaskan eruption in recorded history and the 20th century's largest measured volcanic eruption formed a large summit caldera at Katmai volcano. [3] [4] The eruption happened at a vent about 6 mi (10 km) to the west of Mount Katmai (at the Novarupta Volcano). During over 60 hours, the volcano ...
Mount Spurr (Dena'ina: K'idazq'eni) is a stratovolcano in the Aleutian Arc of Alaska, named after United States Geological Survey geologist and explorer Josiah Edward Spurr, who led an expedition to the area in 1898. The Alaska Volcano Observatory (AVO) currently rates Mount Spurr as Level of Concern Color Code Yellow. [1]
The 1960 eruption of Kīlauea occurred from January 13 to February 19, 1960, on Kīlauea, the most active volcano in Hawaii, US. It followed the eruption of late 1959 in Kīlauea Iki, near the volcano's summit. Fissure vents opened up on the eastern tip of the island of Hawaii, just outside the town of Kapoho.
The volcano, Hawaii's second largest next to neighbor Mauna Loa, started erupting through four scratch-like fissures about 12:30 a.m. in an area 2.5 miles southwest of its caldera, the U.S ...
Novarupta [a] is a volcano that was formed in 1912, located on the Alaska Peninsula on a slope of Trident Volcano in Katmai National Park and Preserve, about 290 miles (470 km) southwest of Anchorage. Formed during the largest volcanic eruption of the 20th century, Novarupta released 30 times the volume of magma of the 1980 eruption of Mount St ...

The Keanakakoi eruption was a VEI-4 eruption that occurred from the summit caldera of Kīlauea volcano in or around November 1790. [ 1 ] [ 2 ] It has been described as the deadliest volcanic eruption in what is now the United States, with more than 400 people having been killed in the event.
