USGS ShakeMap

USGS ShakeMap is a tool that visually displays the intensity of ground shaking during an earthquake across affected areas. Using data from seismographs, it creates detailed maps showing how strongly the earth shook in different locations. These maps help emergency responders, officials, and the public understand which areas experienced severe shaking, guiding response efforts and resource allocation. ShakeMaps are generated quickly after an earthquake and are updated as more information becomes available, providing real-time insights into the event’s impact.
