| (9) Area: | Aleutians Alaska |
| (10) Summit Elevation: | 5676 ft (1730 m) |
| (11) Volcanic Activity Summary: | Reports from fishing boats indicate an eruption of Cleveland volcano occurred at approximately 12:00 AKDT (20:00 UTC). These reports indicate that at sea level the ash may be moving to the northwest. AVO has no information about the height of the ash cloud at this time. |
| (12) Volcanic cloud height: | Unknown |
| (13) Other volcanic cloud information: | Unknown |
| (14) Remarks: | AVO monitors Cleveland Volcano with satellite imagery as weather allows. The lack of a real-time seismic network at Cleveland means that AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions of ash that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery.
