ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Thursday, May 30, 2013, 11:22 AM AKDT (Thursday, May 30, 2013, 19:22 UTC)
55°25'2" N 161°53'37" W,
Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
No evidence of eruptive activity at Pavlof over the past day. Seismic activity remains very low. Satellite observation over the past day show slightly elevated surface temperatures, which are consistent with the cooling of the previously erupted lava. No ash or gas emissions have been detected in satellite data, web camera images, or reported by pilots.
During past eruptions of Pavlof, the style of eruptive activity fluctuated from higher to lower levels. Therefore, this pause in eruptive activity does not necessarily indicate that the eruption has ended. Renewed activity is possible, and may not be preceded by significant seismic activity. AVO will continue to monitor Pavlof closely.
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Satellite observations of Cleveland were mostly obscured by clouds over the past day. No ash emissions have been detected and AVO has received no other reports of activity.
Sudden explosions of blocks and ash are 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.
