January 11, 2022 M 6.8 Nikolski, Alaska Earthquake
Event response pages are a service to help coordinate community science after an earthquake or other notable geophysical event by collecting relevant data. Findings and figures are preliminary and subject to revision.
At 11:35:46 (UTC) on January 11, a magnitude 6.8 earthquake occurred about 70 kilometers off Alaska’s Umnak Island, followed by a magnitude 6.6 event nearby at 12:39:31 (UTC). For more information, see the USGS Earthquake Hazards Program event pages for each.
The event occurred within the footprint of the Network of the Americas (NOTA), a network of continuous GPS/GNSS stations and borehole instruments operated by UNAVCO that monitors plate motion and transient deformation, in addition to other applications.
These data are provided by the Geodetic Facility for the Advancement of Geoscience (GAGE) Facility, operated by UNAVCO, Inc. with support from the National Science Foundation and the National Aeronautics and Space Administration under NSF Cooperative Agreement EAR-1724794. NOTA is a core component of the NSF GAGE Facility. To acknowledge use of these data please follow the acknowledgment guidelines.
