"Cleveland Volcano"

The Alaska Volcano Observatory reports that increased surface temperatures and ash indicate the volcano has entered a period of unrest.

A group of researchers left Unalaska this past weekend for a remote part of the central Aleutians: the Islands of the Four Mountains.

Scientists at the Alaska Volcano Observatory were able to get clear views of two restless volcanoes yesterday. The images show that both Cleveland Volcano in the Aleutian Islands and Pavlof Volcano on the Alaska Peninsula are oozing lava.

Cleveland Volcano continues to be active, with two additional blasts shaking the volcano on Sunday evening, and Monday morning.
