UNAVCO is a community of scientists, educators, and professionals working together to better understand Earth processes and hazards using geodesy. We operate the GAGE Facility on behalf of the National Science Foundation with support from NASA.

September 8, 2021 M 7.0 Acapulco, Mexico Earthquake

At 1:47:47 (UTC) on September 8, 2021, a magnitude 7.0 earthquake occurred near Acapulco, Mexico. The earthquake is associated with the plate boundary, where the oceanic Cocos plate collides with and subducts beneath Mexico. Slip occurred with a reverse motion and centered at a depth of 20 kilometers, producing a local tsunami warning but no warning for other regions in the Pacific.


New and upgraded geodetic stations will serve ShakeAlert

The ShakeAlert earthquake early warning system is much more than the alert message on your phone. Detecting earthquakes, characterizing them, and determining the appropriate warning area takes a tremendous amount of infrastructure. With the completion of a recent Cooperative Agreement with the USGS, UNAVCO has improved West Coast geodetic infrastructure so it can be fully integrated into ShakeAlert.


Plate Motion Calculator

Calculate tectonic plate motion at any location on Earth using one or more plate motion models. The Plate Motion Calculator is a tool that calculates rigid plate motions. Computations can be made at one or more specified locations on Earth.
