Mount Gareloi is an active volcanic peak on Gareloi Island in the Aleutian Islands of Alaska. The volcano forms most of the uninhabited island and is monitored for eruptive activity.
The island’s volcano has produced historical eruptions and volcanic unrest, typically recorded as steam and ash emissions and occasional lava-producing events. The island is remote and not inhabited, so visits are limited to scientific and occasional expedition landings.
The volcano and island are part of the Aleutian volcanic arc and are managed within federal monitoring systems for aviation safety and geological observation. The island’s remoteness means changes in volcanic activity are reported primarily by geological agencies.
Gareloi Island lies in the Aleutian chain in the Bering Sea region of Alaska and is accessible only by boat or aircraft for scientific purposes; it is far from major population centers.
- Active volcano: Located on an uninhabited island in the Aleutian chain and monitored as an active volcano; eruptions commonly produce ash plumes and steam.
