Amak Volcano

Amak Volcano is a basaltic andesite stratovolcano in the Aleutian Islands of Alaska, United States, 618 miles (995 km) from Anchorage. It is located on the eponymous island, 31 miles (50 km) from Frosty Volcano and near the edge of the Alaskan Peninsula's western flank. Only boats are allowed to access the island with a certain permit. Blocky (dotted with flat blocks of minerals and crystals) lava flows stream from its summit to its flanks. Three historical eruptions have taken place – two within the 18th century, the first from 1700 to 1710, and the latter in 1796. The earliest prehistoric eruption was believed to have taken place between 3050 and 2050 BCE.
