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.


UNAVCO building geodetic architecture of ShakeAlert®

UNAVCO recently wrapped up a two-year project upgrading and installing geodetic stations to better serve the ShakeAlert Earthquake Early Warning System, but the work contributing to ShakeAlert is far from over. As a result of a new interagency agreement with the National Science Foundation and the United States Geological Survey, UNAVCO will build and operate the new geodetic data architecture of 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.
