The large earthquake with a preliminary magnitude of M7.0 that occurred this morning at 8:29 AKST north of Anchorage was tectonic in nature and not related to volcanism. For more information on the earthquake, see the NEIC website: https://earthquake.usgs.gov/ AVO has offices in Anchorage and Fairbanks, Alaska. The Fairbanks office is unaffected and continues to monitor Alaska’s volcanoes. The Anchorage facility has power and limited communications. Essential monitoring personnel continue to staff the Anchorage office. Ground-based monitoring data from our Veniaminof, Aniakchak, Okmok, and Korovin networks is currently unavailable following the earthquake; but we continue to monitor those volcanoes using satellite and infrasound data. Veniaminof remains at ORANGE/WATCH, Cleveland, Semisopochnoi, and Great Sitkin remain at YELLOW/ADVISORY.
