Caldera of Veniaminof Volcano in Alaska, USA63.5N 154.4W
This orthorectified image shows Mount Veniaminof, an active stratovolcano located on the Alaska Peninsula. Veniaminof has one of the highest elevations of Alaskan volcanoes. Partly for this reason, it is covered by a glacier that fills most of the caldera.
The volcano’s caldera was created by a colossal eruption around 1750 BC. In modern times the volcano has had numerous small eruptions (over ten of them since 1930); these are located at a cinder cone in the middle of the caldera. The Alaska Volcano Observatory, however, currently rates Veniaminof at Volcano Alert Level normal.
