ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Thursday, February 10, 2011, 11:12 AM AKST (Thursday, February 10, 2011, 20:12 UTC)
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
A local pilot and experienced observer for AVO overflew the volcano early on the afternoon of February 9, and observed minor, repetitive steam emissions rising hundreds of feet above the summit. The snow on the flanks was pristine, with no indications of recent ash emissions. Steam emissions are common at Cleveland and do not indicate an increased level of unrest. Satellite views of Cleveland were mostly obscured by clouds over the previous day.
Without a real-time seismic network at Cleveland, AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions with ash clouds that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery for hours. Low-level ash emissions at Cleveland occur frequently and do not necessarily mean a larger eruption is imminent. AVO continues to monitor the volcano using satellite imagery.
