June 5, 2021 M 5.3 Calipatria, CA 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 17:55:58 (UTC) on June 5, a magnitude 5.3 earthquake 11 kilometers west of Calipatria, California started a swarm of events in the area. The swarm is associated with the Westmorland Fault and the step-over fault system between the San Jacinto and San Andreas faults. For more information, see the USGS Earthquake Hazards Program event page and the Southern California Seismic Network event page.

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-1724794NOTA is a core component of the NSF GAGE Facility.
