Researchers looked at how scientists model the vulnerability of karst formations around the Grand Canyon. They then created a new model that can give land and water managers more information so they can better protect the water system.

A team of researchers has made an important breakthrough that will help better understand the origin and behavior of slow earthquakes. Their work presents unprecedented evidence that slow earthquakes are related to dynamic fluid processes at the boundary between tectonic plates. These slow earthquakes are quite complex, and many theoretical models of slow earthquakes require […]

The 2019 Ridgecrest earthquake sequence, which startled nearby California residents over the 4 July holiday with magnitude 6.4 and magnitude 7.1 earthquakes, included 34,091 earthquakes overall, detailed in a high-resolution catalog created for the sequence.
