The Observatory website allows users to monitor active volcanoes, with seismographs and webcameras that update regularly. AVO now monitors more than 20 volcanoes in Cook Inlet , which is close to Alaskan population centers, and the Aleutian Arc due to the hazard that plumes of ash pose to aviation.
In late May, 2009, activity decreased and the Alaska Volcano Observatory lowered the alert level. A nearly six-month period of relative quiet at the volcano ended on December 27, 2009, with renewed earthquake swarms. The AVO subsequently raised the alert level, and again warned of the possibility of a more vigorous eruption due to dome collapse ...
The Puff model is a volcanic ash tracking model developed at the University of Alaska Fairbanks. It requires windfield data on a geographic grid covering the area over which ash may be dispersed. Representative ash particles are initiated at the volcano's location and then allowed to advect, diffuse, and settle within the atmosphere.
Hundreds of small earthquakes have been reported near a volcano in southeast Alaska believed to have been dormant for at least 800 years. The cause of the quakes under Mount Edgecumbe, a volcano ...

Mount Spurr (Dena'ina: K'idazq'eni) is a stratovolcano in the Aleutian Arc of Alaska, named after United States Geological Survey geologist and explorer Josiah Edward Spurr, who led an expedition to the area in 1898. The Alaska Volcano Observatory (AVO) currently rates Mount Spurr as Level of Concern Color Code Yellow. [1]
