Fisher Caldera is located just 13 miles (21 km) from the Mount Westdahl volcano. The largest volcanic eruption on Earth during the Holocene Epoch (the last 11,700 years) occurred at Fisher Caldera in 8700 BCE.

Mount Aniakchak caldera. Fisher Caldera is located on Unimak Island [1] and named for American geologist Bernard Fisher, who died on June 22, 1946, while exploring the Umnak Pass. [2] It is 8 miles (13 km) by 6 miles (10 km) in area. [1]
The Fisher Caldera is a volcanic crater in the west-central part of Unimak. Some characteristics include many volcanic cones and undrained lakes. It is named for Bernard Fisher, a U.S. Geological Survey geologist who was killed in Umnak Pass.
Eickelberg Peak is an Aleutian Range stratovolcano located along the west rim of Fisher Caldera on Unimak Island of the Aleutian Islands. [5] Precipitation runoff from the mountain's east slope drains into the caldera and from the other slopes into tributaries of the Pogromni River.

It was the last in a series of at least four caldera-forming eruptions there, the earlier known caldera having formed about 1.2 million years ago. [3] This, the last eruption, had an estimated volcanic explosivity index of 8, making it the largest known explosive volcanic eruption in the Quaternary , and one of the largest known explosive ...
