The Abstract for Pavlof Volcano:
On May 13, 2013, the Alaska Volcano Observatory reported seismic activity at Pavlof Volcano increased along with the presence of an intense thermal anomaly at its summit. On May 14, a small lava flow at Pavlof confirmed eruption onset. Elevated seismic activity, lava fountaining, and occasional steam, gas, and ash plumes to 22,000 feet (6700 m) continued until about May 24. Volcanic ash can disrupt air traffic patterns. The Pavlof ash cloud, at altitudes up to 25,000 feet (7,620 m), caused cancellations of more than a dozen regional air traffic flights.
