Activity at Pavlof Volcano
May 14, 2013 | Alaska Volcano Observatory
"Seismic activity at Pavlof Volcano increased this morning commensurate with the presence of an intense thermal anomaly at the summit observed in latest satellite imagery. Similar patterns of seismicity and elevated surface temperatures have previously signaled the onset of eruptive activity at Pavlof. Although not yet visually confirmed, a low-level eruption of lava has likely begun from a summit vent." Quoted from the Alaska Volcano Observatory.
