The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977. We monitor and report earthquakes, assess earthquake impacts and hazards, and research the causes and effects of earthquakes.
Highlights
A Possible Cause of Earthquakes in the Continental Interior
A new map of crustal stress across the U.S. shows that the plate interior stress is variable, with contributions from plate boundary stress, crustal collapse due to gravity, and more local and subtle changes to style, orientation, and earthquake rate.
Oklahoma Study Reveals Possible, Previously Unknown Sources of Earthquakes
Magnetic measurements made during low-altitude airplane flights conducted for the U.S. Geological Survey and the Oklahoma Geological Survey reveal possible deep faults that may contribute to increased seismic activity in response to wastewater injection in certain portions of Oklahoma.
