Description: From McGimsey and others (2005): "On July 25, 2003, an avalanche of snow, ice, and rock occurred at Iliamna volcano, a site of frequent spring and summer avalanches (Neal and others, 1995; McGimsey and Wallace, 1999; McGimsey and others, 2004). The event lasted 4 minutes and was recorded on seismometers located as far away as 75 km (46 mi) on Augustine volcano. The avalanche presumably initiated from the same vicinity as in previous years, a steep portion of the east-southeast flank adjacent to an extensive fumarolic field and large zone of altered rock [see fig. 7 in original text]."
