Mount Okmok

Mount Okmok rises 1,073 meters above sea level and features a 10-kilometer wide caldera containing multiple cinder cones and small lakes.

The volcano experienced a major eruption in 43 BCE, generating substantial ash clouds that potentially influenced climate patterns and historical events in distant regions.

The Aleut people named the caldera Unmagim Anatuu and established settlements near the volcano, utilizing the natural resources of the surrounding landscape.

The Alaska Volcano Observatory maintains monitoring equipment on Mount Okmok to track seismic activity and provide early warnings of potential eruptions.

The caldera floor contains several active vents that released ash clouds during the 2008 eruption, reaching elevations that disrupted regional air traffic.
