Scientists spot lava flows at Cleveland and Pavlof

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 started erupting earlier this month, with six separate explosions sending up multiple ash clouds. The volcano has been quiet since early last week, but the new satellite imagery shows a lava flow coming out of the southeastern side of the crater. The flow is about 100 yards wide, and a mile long.

Scientists at the Observatory first detected activity at Mount Pavlof Monday morning, but weren’t able to visually confirm an eruption. Monday night, a passing PenAir pilot took a photo that shows a fresh, quarter-mile-long lava flow on the volcano’s northern flank, and steam emanating from the summit.

While the aviation alert level for both volcanoes remains at orange, neither has interfered with air traffic. Only Pavlof has a real-time monitoring network, while Cleveland is monitored remotely, using infrasound sensors and satellites.
