ShakeMap is a product of the USGS Earthquake Hazards Program in conjunction with the regional seismic networks. ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and disaster planning.

The ShakeMap Atlas (~14,100 events, 1900-2019) provides a consistent and quantitative description of the distribution of shaking intensity for calibrating global earthquake loss estimation methodologies used in PAGER.
Earthquake Scenarios describe the expected ground motions and effects of specific hypothetical large earthquakes.
