Just before midnight on Saturday May 21, AVO detected seismic and pressure sensor signals associated with a large non-volcanic avalanche on the north flank of Iliamna Volcano. Avalanche events are somewhat common at this volcano. The seismic signals from the avalanche were observed on volcano monitoring networks throughout Cook Inlet and as distant as the Katmai region 250 km (155 miles) away. There is no indication of any volcanic activity associated with this avalanche.
Iliamna volcano is located on the western side of lower Cook Inlet in the Lake Clark National Park. Iliamna is a snow-covered stratovolcano which rises 10,020 feet above sea level. Although steam plumes occur on its eastern flanks, there has been no historic volcanic activity at Iliamna. Iliamna is located 225 km (140 miles) southwest of Anchorage and 113 km (70 miles) northwest of Homer.
