Abstract
The Alaska Volcano Observatory (AVO) monitors 41 historically active volcanoes along the Aleutian Arc. Twenty are seismically monitored and for the rest, the AVO monitoring program relies mainly on daily analysis of satellite images, pilot reports, and observations of local residents and ship's crews. In 1999, AVO responded to eruptive activity or suspect volcanic activity at 7 volcanic centers: Wrangell, Shrub mud volcano, Iliamna, Veniaminof, Pavlof, Shishaldin, and Vsevidof volcanoes. Of these, in 1999, AVO had real-time, continuously recording seismic networks at Iliamna, and Shishaldin. The phrase “suspect volcanic activity” (SVA), used to characterize several responses, is an eruption report or report of unusual activity that is subsequently determined to be normal or enhanced fumarolic activity, weather-related phenomena, or a non-volcanic event.
In addition to responding to eruptive activity at Alaska volcanoes, AVO also disseminated information for the Kamchatkan Volcanic Eruption Response Team (KVERT) about the 1999 activity of four Russian volcanoes: Sheveluch, Klyuchevskoy, Bezimianny, and Karymsky volcanoes.
