Seismic Intensity Estimates

Covering California, Nevada, Oregon, and northern Mexico.

The goal of the Intensity Lab is to change how we talk about earthquakes, moving past a single magnitude number to focus on site-specific seismic intensities, which can provide the essential information needed to make smart decisions after the shaking stops.
