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

AVO detected thermal anomalies at Cleveland Volcano in several satellite image last night. No other activity has been reported. AVO continues to monitor the volcano using satellite imagery.

Without a real-time seismic network at Cleveland, AVO is unable to track local earthquake activity related to volcanic unrest. Low-level ash emissions at Cleveland occur frequently and do not necessarily mean a larger eruption is imminent. Short-lived explosions with ash clouds or plumes that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery.
