Mount Okmok live camera — Alaska
The camera looks in from the rim of a caldera 10 km across. Young cinder cones and lava flows are scattered over its floor.
Sample October 2026What you are looking at
Cloud covers the top half of the picture, with blue sky showing only in the upper left corner. Below it the rim of the caldera lies across the frame, and a single rounded hill stands up dark near the middle. A band of sunlight falls on the far rim. The floor is a flat sheet of ash and sand, and a crumbling slope fills the near right.
Okmok sits at the north-eastern end of Umnak Island in the Aleutians and reaches 1,073 m at its highest point. The caldera floor averages about 370 m, so standing on the rim means looking down nearly 700 m. The nearest settlement, Nikolski, is 73 km to the south-west; Unalaska is 117 km to the north-east.
Two eruptions built this rim. The older one came about 8,200 years ago. The younger one came in early 43 BCE, a date fixed in 2020 when the chemistry of volcanic ash preserved in Arctic ice was matched to this mountain. The years 43 and 42 BCE rank among the coldest of recent millennia in the Northern Hemisphere.
More recently the volcano erupted from 12 July to 19 August 2008. Magma met groundwater, a new vent opened in the north-east of the caldera, and a hill 253 m high named Ahmanilix was piled up in a single summer. It was the first eruption of that kind in the United States since 1977.
The Aleutians draw fog and low cloud, and days when the whole caldera is buried in white are not unusual. This is a still camera. Alaskan time runs 17 to 18 hours behind Japan, so about five in the morning in Japan is the middle of the day there.
