GEM Global Active Faults

The GEM Global Active Faults project is compiling a global dataset of active faults (link here) for seismic hazard assessment as well as research, education and general interest. While this is a work in progress, we've got a lot of the world covered already. Check out the map below, and click on any fault for more information. Thanks!

The faults are colored by kinematcs; blue faults are dextral, purple faults are sinistral, red faults are normal and black faults are reverse. See this map full screen

Many thanks to the many geoscientists and organizations who have made the regional catalogs used in this work.

This study is made possible by the support of the American People through the United States Agency for International Development (USAID.) The contents of this study are the sole responsibility of the GEM Foundation and do not necessarily reflect the views of USAID or the United States Government.
