AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, June 17, 2013, 12:04 PM AKDT (Monday, June 17, 2013, 20:04 UTC)


PAVLOF VOLCANO (VNUM #312030)
55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

There has been no significant change in the seismicity at Pavlof in the past 24 hours. Seismic tremor continues, but at lower amplitudes than previously. No elevated surface temperatures were detected in satellite images during the past 24 hours. No plumes were visible in satellite images, and web camera images show mostly cloudy conditions.

Although activity at Pavlof has declined, eruptive activity could increase again with little warning.



VENIAMINOF VOLCANO (VNUM #312070)
56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

The eruption of Veniaminof volcano continues. 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. Volcanic tremor continues unchanged in the past 24 hours. FAA web camera images have been obscured by clouds.








CLEVELAND VOLCANO (VNUM #311240)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

No elevated surface temperatures were observed in satellite images. We have received no other reports of activity at the volcano.

Sudden explosions of blocks and ash are still possible with little or no warning. Ash clouds, if produced, could exceed 20,000 feet above sea level. If a large ash-producing event occurs, nearby seismic, infrasound, or volcanic lightning networks should alert AVO staff quickly. However, for some events, a delay of several hours is possible. Cleveland volcano does not have a local seismic network and is monitored using only distant seismic and infrasound instruments and satellite data.
