Veniaminof volcano (Alaska Peninsula, USA) activity update

Dienstag Jun 25, 2013 06:22 | VON: T

Activity has continued over the past days with little changes. Direct observations are difficult, but for the first time, some incandescence from the central cone was observed on the webcams yesterday. This is likely due to the presence of a lava flow and/or spattering from a vent.
The latest update from the Alaska Volcano Observatory (AVO):
"Volcanic tremor continues to be detected in seismic data indicating that the eruption of Veniaminof Volcano continues. Satellite images obtained over the past 24 hours show elevated surface temperatures at the intracaldera cone and earlier today a plume was observed extending to the southwest from the cone. The plume was probably generated by the interaction of lava with snow and ice and probably consisted mostly of water vapor and possibly small amounts of ash. Views of the volcano from the web camera in Perryville did not show any obvious ash clouds, although images obtained just before sunrise showed a small area of incandescence on the intracaldera cone consistent with the production of small amounts of lava and or spatter.
"It is possible for activity at Veniaminof Volcano to increase above its current level at any time and more vigorous ash emissions may result. Sustained periods of volcanic tremor may correspond with continuous ash emission which may not be detected in satellite data, especially if ash plumes remain below 15,000 to 20,000 feet above sea level. Brief bursts of ash emission and small explosions with ash fall limited to areas on the flanks of the volcano are likely to occur while the volcano is at its current level of unrest. A larger explosive episode and associated ash emission is not expected at the current level of unrest; however, this remains possible and would be evident in seismic data.

The eruption continues. A lava flow is being erupted from the central intra-caldera cone, recent satellite images suggest as they show very high elevated surface temperatures in this area. Since about 10 hours ago, a seismic swarm and continuous tremor have appeared indicating probably an increase in this activity. ... [mehr]

The eruption continues at low levels. Recent satellite images show very high elevated surface temperatures at the intracaldera cinder cone consistent with continued effusion of lava. No plumes have been observed in satellite images nor reported by pilots or local observers. (AVO) [mehr]

Seismic tremor continued to slowly but steadily increase yesterday, then dropped temporarily and has been increasing again today. AVO reports an intermittent, low-level steam plume issuing from the central cone within the caldera. No elevated surface temperature were visible in satellite images. No other activity was confirmed by AVO. [mehr]
