Low-levels of seismicity continued at Veniaminof over the past week. Satellite images during clear periods show no evidence of elevated surface temperatures that were commonly observed during eruptive activity from June to mid-September, 2013. Web camera images show no evidence of steaming or ash emissions. Although it appears that the eruption has ended, it is possible that this is only a temporary waning of activity, and that more vigorous activity could resume. Pauses in eruptive activity such as this are not uncommon at this volcano. AVO will continue to monitor the volcano closely.

CORRECTION OF AVIATION COLOR CODE AND VOLCANO ALERT LEVEL
Based on a decline in seismic activity and the lack of evidence of eruptive activity observed in satellite and web camera imagery over the past week, AVO lowered the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory earlier today.
Low-level seismic tremor continues at Veniaminof. Elevated surface temperatures were observed in satellite data this week though at low levels and are likely indicative of cooling lava flows. No eruptive activity was observed in web camera imagery or by pilots over the past week.
It is possible that this is only a temporary waning of activity in the eruption that began in June 2013, and that more vigorous activity could resume. Pauses in eruptive activity such as this are not uncommon at this volcano. AVO will continue to monitor the volcano closely.

Seismic tremor continues though at decreased levels compared to prior weeks. Elevated surface temperatures were observed in satellite data over the past 24 hours though the signal is diminished compared to times when effusion of lava was known to be occurring. Elevated temperatures may therefore, be indicative of cooling lava flows or low-level effusion of lava. No eruptive activity was observed in webcam images.

Weak thermal anomalies were observed in satellite data over the past 24 hours at Veniaminof. Seismic tremor continues though at decreased levels compared to prior weeks. No unusual activity was observed in webcam images. These data indicate that the effusion of lava from the active vent may be ongoing though diminished.

The eruption of Veniaminof continued over the past week. Similar to previous weeks and months, the eruption was characterized by lava effusion and fountaining and production of intermittent small steam, gas, and ash plumes that rise hundreds of feet above the active vent. These plumes are likely restricted to within a few miles of the caldera. Seismic tremor associated with this activity has been declining in amplitude over the past two weeks and is currently similar to low level tremor observed in late August. Tremor and rates of lava effusion have waxed and waned over the course of this eruption. During periods of clear weather, the view from the FAA webcam in Perryville showed an intermittent plume from the intracaldera cone. Elevated surface temperatures, consistent with lava effusion, have been detected over the past week in satellite images.
Ash fall from current activity is not expected to be significant and likely will be less than 1/16 inch, although areas within a few miles of the active cone could receive thicker amounts of ash fall. Information about volcanic ash and its potential effects can be found on the AVO web page (www.avo.alaska.edu).
Throughout the current eruption, which began in June 2013, the volcano has experienced fluctuating levels of lava effusion and ash emission. Eruptive activity could intensify at any time, leading to higher and more far traveled ash plumes.

The eruption of Veniaminof continues. Seismic tremor continues to be observed though no unusual activity was observed in cloudy satellite images. The FAA webcam in Perryville is obscured by heavy fog. The effusion and fountaining of lava from the active vent are likely ongoing.
