Gareloi Hazard Report Released
AVO-USGS has published the preliminary volcano-hazard report for Gareloi.

Gareloi Volcano (178.794°W and 51.790°N) is located on Gareloi Island in the Delarof Islands group of the Aleutian Islands, about 2,000 kilometers west-southwest of Anchorage and about 150 kilometers west of Adak, the westernmost community in Alaska. This small (about 10 kilometer) volcano has been one of the most active in the Aleutians since its discovery by the Bering expedition in the 1740s, though because of its remote location, observations have been scant and many smaller eruptions may have gone unrecorded.

KASATOCHI VOLCANO
52°10'9" N 175°30'41" W, Summit Elevation 1030 ft (314 m)
Current Aviation Color Code: YELLOW
Current Volcano Alert Level: ADVISORY

Possible seismic activity at Kasatochi continues. Satellite views were cloudy last night.

Kasatochi Volcano does not have a seismic network, thus AVO depends on networks on neighboring islands to monitor earthquake activity there. For this reason, low-level seismicity may not be detected and renewed volcanic activity is possible at any time with little or no warning.

OKMOK VOLCANO
53°23'49" N 168°9'58" W, Summit Elevation 3520 ft (1073 m)
Current Aviation Color Code: YELLOW
Current Volcano Alert Level: ADVISORY

Seismicity at Okmok volcano continues at low levels. Clouds obscure the volcano in satellite views.

Although the level of seismicity is relatively low, it is possible for vigorous ash emissions to resume at any time.

CLEVELAND VOLCANO
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Aviation Color Code: YELLOW
Current Volcano Alert Level: ADVISORY

Clouds continue to obscure Cleveland volcano in satellite and web camera views. AVO received no reports of activity at the volcano.

AVO monitors Cleveland Volcano with satellite imagery as weather allows. The lack of a real-time seismic network at Cleveland prevents AVO from tracking 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.
