Pavlof volcano news & activity updates:

Pavlov volcano (Alaska Peninsula, USA) activity update

The eruption had increased yesterday and produced ash plumes rising up to about 8.5 km (28,000 ft), but has decreased in strength again today.
Seismicity had climbed to the highest levels since the beginning of the eruption, suggesting that the magma supply was reinvigorated into a new explosive phase. Ash fall was reported in communities to the southwest of Pavlof, including King Cove, at 48 km (30 miles) distance.
Today, seismic activity has declined gradually and now consists of intermittent bursts of tremor and occasional small explosions. Periods of continuous tremor and intermittent small explosions are likely associated with lava fountaining and minor ash production.
Satellite data over the past 24 hours has shown a plume extending to the northwest from the volcano containing a small amount of ash. Strong thermal signals at the summit also have been evident in satellite imagery. Pilot reports this morning have indicated that plumes are rising to lower levels than yesterday and are generally in the range of 20,000 to 25,000 feet above sea level. AVO has received no reports of ash fall on nearby communities today.
At the current level of unrest, some lava fountaining and ash emission are likely occurring. Lava fountaining is likely producing spatter-fed lava flows that are descending the flanks of the volcano and will occasionally interact with snow and ice to produce volcanic mudflows and intermittent steam plumes. It is possible for the character of the eruption to change at any time and more vigorous seismicity and ash emissions may result. (AVO)

The eruption continues at low levels. Seismic tremor and occasional explosions are being detected in seismic data and indicate that minor ash emission is likely occurring, although no ash plumes were detected on satellite data over the past day. Read all
