From Wikipedia
Kasatochi Island, also known as Kasatochi volcano, is an active stratovolcano and part of the Andreanof Islands subgroup of the Aleutian Islands of southwestern Alaska. On 7 August 2008, Kasatochi began erupting explosively with an ash plume reaching 45,000 feet (14,000 m). The eruption lasted for 24 hours and destroyed most life on the island. Since the eruption, it has been the site of research on the primary succession of species back onto the island. It currently does not support any consistent human population.
