Mount Shishaldin

Common card · No. 492130

Shishaldin Volcano, or Mount Shishaldin (), is one of six active volcanoes on Unimak Island in the eastern Aleutian Islands of Alaska. It is the highest mountain peak of the Aleutian Islands, rising to a height of 9,373 ft (2,857 m) above sea level. It is located within Alaska Maritime National Wildlife Refuge. Shishaldin's magma supply is generated via flux melting above the Aleutian Trench, where the Pacific Plate subducts beneath the North American Plate. Due to its remote location and frequently inclement weather, the Alaska Volcano Observatory (AVO) monitors the volcano remotely via satellite and a seismic network deployed in 1997. Shishaldin is one of the most active volcanoes in the Aleutian Islands, with 40 confirmed eruptions in the last 11,700 years. Notably, Shishaldin produced a sub-Plinian (VEI 3) eruption in 1999.
