Remobilized Katmai 1912 ash: community events and health hazard analysis
Posted: September 03, 2015

Air quality monitor to be deployed on Kodiak

Alaska Volcano Observatory scientists will hold two community events on Kodiak Island next week. Alaska Volcano Observatory scientists are deploying instruments in two locations on Kodiak Island to monitor air quality during strong northwesterly winds, when old loose volcanic ash from the Katmai/Novarupta 1912 eruption can be picked up and reworked into dust clouds from the Valley of Ten Thousand Smokes and carried over Shelikof Strait, Kodiak Island and the Gulf of Alaska. These clouds contain volcanic ash shards that are a known hazard to aviation. Scientists are studying other effects of the remobilized ash fallout on the ground and whether there is a public health hazard.

OTHER ALASKA VOLCANOES

Other Alaska volcanoes show no signs of significant unrest: http://www.avo.alaska.edu/activity/

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.
