Two hours after lowering the aviation code for an Eastern Aleutian volcano, it’s back at the highest alert level.
The reasoning? According to the Alaska Volcano Observatory, there was a significant explosion at Bogoslof volcano Thursday afternoon.
The observatory detected a raised level of seismicity around 1:30 p.m. as well as reports from the World Wide Lightning Detection Network of lightning strikes. A pilot reported seeing a volcanic cloud at 35,000 ft.
The volcano has been erupting since mid-December.
