The Islands of the Four Mountains comprises eight islands in the central Aleutians (Amukta, Chagulak, Yunaska, Herbert, Carlisle, Chuginadak, Uliaga, and Kagamil).
This group of islands is also home of six stratovolcanoes: Carlisle (Carlisle Island), Cleveland (Chuginadak Island), Herbert (Herbert Island), Kagamil (Kagamil Island), Tana (Chuginadak Island) and Uliaga (Uliaga Island).
A new supervolcano in Alaska
In a
new study, scientists suggest that these islands and stratovolcanoes are part of a single giant volcano.
And that this newfound caldera is similar to the Yellowstone Caldera and other super volcanoes responsible for cataclysmic super-eruptions.
Studying Mount Cleveland, the geologists have gathered multiple evidences showing that the 8 islands could belong to one interconnected caldera.
Although further studies are needed, everything they looked at lines up with a caldera in this region!
This would be the first underwater caldera in the Aleutian Islands. The caldera hypothesis would also help explain what makes Mount Cleveland so active and what types of eruptions are expected in the future. More volcanic news on
