Significant Earthquakes Archive
The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977, and the USGS Advanced National Seismic System (ANSS) was established by Congress as a NEHRP facility. The USGS and its partners monitor and report earthquakes, assess earthquake impacts and hazards, and perform research into the causes and effects of earthquakes.

Preserving Historic Earthquake Records and Photos of the Instruments that Recorded Them
A project to scan a small selection of the film chips of historical earthquake recordings to digital files was started in 1996. In addition to archiving historic data from the early years, the USGS has also worked to archive photos and descriptions of early seismometers.
Microseismic Events Associated with the Oroville Dam Spillway
On 14 February 2017, two small seismic events occurred in proximity to the Oroville Dam in the Sierra Nevada foothills, California. A new report found 19,000 smaller‐magnitude events near the Oroville spillway that were similar to the events and occurred in clusters that strongly correlate with periods of spillway discharge.
