After two eruptions in as many days, scientists are closely watching a volcano in the eastern Aleutians. There’s no equipment on Bogoslof volcano, but The Alaska Volcano Observatory (AVO) is keeping tabs with satellite imagery and nearby seismic monitors.

 

Bogoslof volcano is tiny -- like city park tiny. The uninhabited island is less than a quarter of the size  of Central Park in New York City.
