ALASKA VOLCANO OBSERVATORY WEEKLY UPDATE U.S. Geological Survey Friday, October 24, 2014, 12:10 PM AKDT (Friday, October 24, 2014, 20:10 UTC)
58°16'44" N 154°57'12" W,
Summit Elevation 6716 ft (2047 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN
Strong winds in the Katmai area picked up loose 1912 volcanic ash and carried it east again this week on Thursday (10/23/14). AVO detected a cloud of resuspended ash blowing from the vicinity of Katmai and the Valley of Ten Thousand Smokes across and beyond Kodiak Island. The National Weather Service estimated the top of the plume at 4,000 feet (1,219 m) above sea level.
This phenomenon is not the result of volcanic activity and occurs seasonally in the spring and fall during times of high winds and dry snow-free conditions in the Katmai area and other young volcanic areas of Alaska. No eruption is in progress. All of the volcanoes of the Katmai area (Snowy, Griggs, Katmai, Novarupta, Trident, Mageik, Martin) remain at color code GREEN.
Resuspended volcanic ash should be considered hazardous and could be damaging to aircraft and health. For more information on volcanic ash and human health, visit the following website: http://volcanoes.usgs.gov/ash/.
AVO scientists conduct daily checks of earthquake activity at all seismically-monitored volcanoes, examine web camera and satellite images for evidence of airborne ash and elevated surface temperatures, and consult other monitoring data as needed.
The Alaska Volcano Observatory is a cooperative program of the U.S. Geological Survey, the University of Alaska Fairbanks Geophysical Institute, and the Alaska Division of Geological and Geophysical Surveys.
