Amak Volcano

Amak Volcano is a 488-meter stratovolcano on Amak Island, the easternmost of the Aleutian Islands, sitting in Bristol Bay just north of the Alaska Peninsula. Geologically compact at roughly one cubic kilometer in volume, it has a documented eruptive history: blocky lava flows were produced between 1700 and 1710 and again in 1796, with older andesitic flows estimated at 4,000 to 5,000 years old still visible across its flanks. The volcano is actively monitored by the Alaska Volcano Observatory. With no regular access infrastructure, Amak remains the domain of geologists and ornithologists — the island doubles as an important seabird nesting ground for species of the Bering region.
