ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Tuesday, July 15, 2008, 12:48 PM AKDT (Tuesday, July 15, 2008, 20:48 UTC)
53°23'49" N 168°9'58" W,
Summit Elevation 3520 ft (1073 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: RED
Okmok Volcano continues to erupt. Seismicity, though below this weekend's intensity, has remained steady over the last 24 hours. Satellite data continue to show a long (~250 km) plume moving east; the height of the plume is approximately 30,000 ft above sea level.
The volcano is currently at aviation color code RED and alert level WARNING. All areas immediately around the volcano are considered hazardous. Airborne ash and gas continues to drift with the wind and pose a hazard to aviation in the area. Additional ash fall will occur on Umnak Island and possibly adjacent islands as long as the eruption continues.
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Satellite and webcam views continue to be cloudy today. AVO has received no reports of eruptive activity at the volcano.
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.
