Current Status Report
Sunday, August 5, 2007 1:20 PM AKDT (2120 UTC)
52°49'20" N169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Aviation Color Code: ORANGE
Current Volcano Alert Level: Watch
Clouds have prevented views of activity at Cleveland in the last 24 hours. However, in one partly cloudy image, a slight thermal anomaly possibly indicating continued activity was noted.
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.
KOROVIN VOLCANO (ATKA ISLAND)
52°22'48" N174°9'22" W, Summit Elevation 5030 ft (1533 m)
Current Aviation Color Code: YELLOW
Current Volcano Alert Level: Advisory
Intermittent, low-level seismic activity continues at Korovin. Cloudy conditions continue to prevent clear satellite views.
Korovin has erupted several times in the past 200 years, most recently in 1998. Eruptions typically produce minor amounts of ash and occasional, small lava flows. Ash plume heights could exceed 20,000 ft above sea level. Korovin occasionally produces large steam plumes from its summit.
