What work is the USGS doing to better understand the occurrence of injection-induced earthquakes?

USGS supports both internal and external (university-based) research on the causes of induced earthquakes. This research has a focus on injection-induced earthquakes, both from wastewater disposal and from enhanced geothermal technologies. USGS and its university partners have also deployed seismometers at sites of known or possible injection-induced earthquakes in Arkansas, southern Colorado, Oklahoma, and Ohio. The USGS is also providing advice to the Environmental Protection Agency about how to assess the earthquake hazard associated with wastewater injection activities at Class II disposal wells.
