Pavlof volcano news & activity updates:
Pavlov volcano (Alaska Peninsula, USA) activity update
Monday May 27, 2013 07:50 AM | BY: T
The eruption continues at low levels (both as surface lava emission and seismic activity).
AVO mentions that "during past eruptions of Pavlof, the style of eruptive activity fluctuated from higher to lower levels. Therefore, this apparent lower-level activity does not necessarily indicate that the eruption is ending. Although the activity to date has been characterized by relatively low-energy lava fountaining and ash emission, more energetic explosions could occur without warning that could place ash clouds above 20,000 ft.
"Depending on wind direction and strength, trace to minor ash fall may occur on local communities downwind. Information about mitigating the effects of volcanic ash can be found on the AVO web page.

Weak activity (probably minor lava effusion) continues at the volcano, visible on satellite imagery as a thermal anomaly. AVO only observed degassing and almost no ash emissions, but maintains orange alert level in case eruptive activity restarts. [more]

The eruption at Pavlov continues but seismic and eplosive-effusive eruptive activity have dropped compared to the day before yesterday when an ash plume reached 7,000 m altitude and was visible from space. [more]

The eruption continues with no significant changes. Small lava fountaining, explosions, and the explosive interaction of the lava flow with snow and ice generate a plume of steam, ash, and gas, occasionally reaching up to 22,000 ft. above sea level, and extending primarily southeast from the volcano over the North Pacific Ocean visible in satellite images. ...

The eruption continues with lava fountaining, an active lava flow and ash emissions, accompanied by continuous seismic tremor. Aerial observations suggest that the interaction of lava and ice on the upper slope of the volcano create mud flows and pyroclastic flows. ... [more]

The eruption continues with lava fountaining at the summit that feeds a lava flow now over 100 m long and produces a continuous ash, steam, and gas plume extending downwind from the volcano for 50 to 100 km at an altitude of about 20,000 ft above sea level. This morning the cloud was carried to the southeast. Satellite images show persistent elevated surface temperatures at the summit and on the northwest flank. ... [more]
