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 focuses on injection-induced earthquakes, including from wastewater disposal, enhanced geothermal technologies, and at carbon dioxide sequestration sites. USGS and its university partners have also deployed seismometers at sites of known or possible injection-induced earthquakes in Arkansas, Colorado, Kansas, Oklahoma, Ohio and Texas. The USGS is also developing methods to assess the earthquake hazard associated with wastewater injection activities. The USGS also works closely with the Environmental Protection Agency, state and local regulators, and state geological surveys to better understand these earthquakes and mitigate the hazard from them.
