The Alaska Volcano Observatory said Bogoslof, on a tiny island about 60 miles west of Unalaska, erupted twice at about 1:20 p.m. and 2 p.m. Wednesday. Another eruption of Bogoslof volcano in the Aleutian Islands sent an ash cloud east over the Alaska Peninsula and Kodiak Island on Wednesday, disrupting aviation in the region and producing the potential for land-based ashfall.
An eruption on Bogoslof Island of the Aleutian Islands disrupts air transportation routes, distributing tephra over populated areas, including Kodiak Island, 660 miles (1,060 km) away from the volcano.
