September 19, 2022 M7.6 Michoacán, Mexico 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 18:05:06 UTC on September 19, a magnitude 7.6 earthquake occurred on the coast of Michoacán, Mexico. For more information, see the USGS Earthquake Hazards Program event page. This was followed by a nearby magnitude 6.8 earthquake at 06:16:09 UTC on September 22.

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. Stations near the event for which UNAVCO provides data were built as part of the TLALOCNet collaboration with Universidad Nacional Autonoma de Mexico (UNAM). As noted in the download list, some stations are currently supported by UNAVCO as part of NOTA, while the remainder are operated by UNAM.

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.
