Explosions at the Cleveland Volcano
Multiple explosions were detected Saturday morning at the remote Cleveland Volcano in the Aleutian Islands. 3 explosive events were detected. The first came at 5-am Saturday morning, followed by a second explosion at 7:17-am. The third explosive event was recorded at 11:44-am.
The Alaska Volcano Observatory notes that the infrasound signals suggest the explosions were low-level and didn't last very long. Satellite images detected a small, low-altitude ash cloud. AVO also detected elevated surface temperatures at the summit of the volcano.
Shortly after the first explosion was detected Saturday morning AVO increased the volcano alert level to "WATCH". They also increased the aviation color code up to "ORANGE". The Cleveland Volcano has been the most active volcano in Alaska in recent years. It's on an uninhabited island in the east central Aleutian Islands. The nearest community is Nikolski about 45-miles to the west.
