Anchorage -- Okmok volcano is showing signs of settling down while Cleveland volcano is just getting started.

Cleveland began erupting in the Aleutians Monday, sending ash nearly 17,000 feet high. Pilots are reporting surface ash 50 miles away.

About 90 miles east of Cleveland volcano, Okmok has slowed to eruptions every 10 to 15 minutes or so, after nearly-constant eruptions this weekend.

The Alaska Volcano Observatory says a red alert is still in place for Okmok but seismic activity is considerably slower.

Okmok, about 60 miles southwest of Dutch Harbor, began erupting suddenly July 12.
