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 weak thermal anomaly was seen in satellite images of Cleveland volcano this morning. No reports of activity have been received.
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. The most recent possible ash cloud was detected on September 12, 2010, though weak thermal anomalies have been regularly detected for the past eight months through February 2011. AVO continues to monitor the volcano using satellite imagery.
