ANCHORAGE, Alaska (AP) – One of Alaska’s most active volcanos has calmed down since spewing ash up to 35,000 feet into the air over the weekend, but scientists said Monday the volcano has a pattern of prolonged eruptions of varying intensity. They’re not ready to consider this explosion over.

Pavlof Volcano began erupting Wednesday, culminating with a major blast Saturday that lasted seven or eight hours before its seismic activity dramatically dropped.

The National Weather Service warned aircraft to avoid the area over the weekend because of the ash plume.
