It is located about 25 km (16 mi) west of the U.S. Navy installation and port on Adak Island. The volcano erupted intermittently through much of 1994, dusting the community of Adak at least once with fine ash.
A steam-driven explosion took place at Kanaga on December 18, 2023, after months of elevated seismic activity on the island throughout the year. The current volcanic unrest at Kanaga continues to present day and is being monitored by the Alaska Volcano Observatory.[2] Its previous eruption was in February 2012.
