According to AVO (Alaska Volcano Observatory) Pavlof volcano
continues to erupt. Lava fountaining at the summit has been observed
and photographed, and a continuous ash, steam, and gas cloud generated
by the activity extends downwind from the volcano for 50 to 100 km at an
altitude of about 6 km (20,000 ft) above sea level.
On the morning of Thursday, May 16, 2013 the cloud was carried to the
southeast, AVO reports. Satellite images show persistent elevated
surface temperatures at the summit and on the northwest flank,
commensurate with the summit lava fountaining and resulting lava flow.
AVO raised Volcano Alert Level from Advisory to Watch and Aviation Color Code from Yellow to Orange. Seismic activity remains elevated with nearly continuous tremor recorded on the seismic network, the agency reported.

satellite, shows Pavlof on May 16, 2013. A brown ash plume blew from
the summit towards the southeast, and gray ash from earlier explosions
covered the snow on the volcano’s upper slopes. To the northeast,
additional ash rose from an ongoing lava flow. (NASA Earth Observatory
