ShakeMap

This repository holds the latest version of the ShakeMap code. ShakeMap is a system for rapidly characterizing the extent and distribution of strong ground shaking following significant earthquakes. The code is primarily written in the Python programming language.

To receive updates on ShakeMap please sign up at Gov Delivery. We also encourage requests, questions, and discussions through the Github issues tab associated with this repository. You may contact the developers at shakemap@usgs.gov.
