Shishaldin Volcano, or Mount Shishaldin (/ʃɪˈʃældən/), is one of six active volcanoes on Unimak Island in the eastern Aleutian Islands of Alaska.[1] It is the highest mountain peak of the Aleutian Islands, rising to a height of 9,373 ft (2,857 m) above sea level.[2][3] Shishaldin's magma supply is generated via flux melting above the Aleutian Trench, where the Pacific Plate subducts beneath the North American Plate.[4] 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.[3] Shishaldin is one of the most active volcanoes in the Aleutian Islands, with 40 confirmed eruptions in the last 11,700 years.[5] Notably, Shishaldin produced a sub-Plinian (VEI 3) eruption in 1999.[5][6][7]
