Seismic data around Alaska, provided by the Alaska Regional Network, 1987-Present

The Alaska Earthquake Center operates the primary seismic monitoring network and seismic data archive for the state of Alaska. As of 2022-09-30 the Alaska Earthquake Center maintains and acquires data from 253 sites in the Alaska Geophysical Network. This includes: 209 free field broadband stations, about 85 of which have co-located strong motion sensors, 107 of which have infrasound data streams, and 67 of which have meteorological sensor packages; 23 strong motion sites in the greater Anchorage and Mat-Su Valley region; 8 strong motion sites in Fairbanks; 7 strong motion sites located in coastal communities from Chignik to Yakutat; 1 structural array located in the Engineering Learning and Innovation Facility on the University of Alaska Fairbanks campus; and 2 Netquake sites in Fairbanks that record only triggered data (these are not included in the data return rates). We acknowledge the Alaska Native nations upon whose land our study area resides and observe the stewardship of the traditional inhabitants of the region.
