ALASKA VOLCANO OBSERVATORY WEEKLY UPDATE
U.S. Geological Survey

No eruptive activity or significant unrest has been detected at volcanoes in Alaska this week.

Monitoring of Alaskan volcanoes

The Alaska Volcano Observatory monitors daily all volcanoes in Alaska through a combination of local seismic networks, regional infrasound detectors, global lightning networks, satellite imagery, and web cameras. Volcanoes assigned aviation color code GREEN and volcano alert level NORMAL are monitored by a local seismic network capable of locating small earthquakes with reliable data transmission. Unassigned volcanoes are monitored by regional seismic and infrasound networks that can detect more significant activity, as well as satellite images.
