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.
