Alaska volcano's week-long eruption spews another massive ash cloud

An ongoing eruption of a remote volcano in Alaska’s Aleutian Islands produced an ash cloud so large Tuesday warnings were sent to pilots about potentially dangerous conditions. The ash cloud with an initial height of over 5.5 miles was drifting south-southeast from Shishaldin Volcano. The volcano is about 700 miles southwest of Anchorage. It sits near the middle of Unimak Island, and the island’s 65 or so residents live about 25 miles northeast of the volcano. Shishaldin has been erupting since July 11, and on Friday sent two large ash clouds into the sky. Volcanic ash can cause a jet engine to shut down.
