AVO infrasound detected a possible explosion at Cleveland Volcano this morning at 5:00AM AKDT )13:00 UTC). The infrasound signals suggest that this was a relatively short duration, low-level explosion. No eruption cloud has been detected in available satellite views. AVO received no other reports of activity.
