Bogoslof Volcano erupted Tuesday night for the first time in two months.
The eastern Aleutian volcano blew around 10:30 p.m., spewing ash 34,000 feet into the air.
The explosion lasted about 73 minutes, according to the Alaska Volcano Observatory.
While seismic activity has since stopped, scientists say Bogoslof could erupt again with little warning. They’ve also issued a marine advisory for potential ash fall in the region between Cape Sarichef and Nikolski.
