Earthquake Hazards Program
The USGS monitors and reports on earthquakes, assesses earthquake impacts and hazards, and conducts targeted research on the causes and effects of earthquakes. We undertake these activities as part of the larger National Earthquake Hazards Reduction Program (NEHRP), a four-agency partnership established by Congress.

Revisiting an enigma on California's north coast: The Mw6.5 Fickle Hill earthquake of 21 December 1954 Revisiting an enigma on California's north coast: The Mw6.5 Fickle Hill earthquake of 21 December 1954
Many earthquakes occur along the North Coast of California in the vicinity of the Mendocino Triple Junction (MTJ), where the Pacific, Gorda, and North American (NA) plates meet, and on the adjacent plate boundaries. The MTJ marks the nexus of the Mendocino and San Andreas faults with the Cascadia subduction zone (CSZ). Historically, most large earthquakes around the MTJ have been within...
Magnitude, depth and methodological variations of spectral stress drop within the SCEC/USGS Community Stress Drop Validation Study using the 2019 Ridgecrest Earthquake Sequence Magnitude, depth and methodological variations of spectral stress drop within the SCEC/USGS Community Stress Drop Validation Study using the 2019 Ridgecrest Earthquake Sequence
We present the first ensemble analysis of the 56 different sets of results submitted to the ongoing Community Stress Drop Validation Study using the 2019 Ridgecrest, California, earthquake sequence. Different assumptions and methods result in different estimation of the source contribution to recorded seismograms, and hence to the source parameters (principally corner frequency, fc...
Reflections on a trio of North American earthquakes in 1925 Reflections on a trio of North American earthquakes in 1925
In 1925, three moderately large damaging earthquakes occurred in North America over four months: the 28 February (local time; LT) M 6.2 Charlevoix, 27 June (LT) M 6.6 Montana, and 29 June M 6.5 Santa Barbara earthquakes. The centennial anniversaries of these events motivated this retrospective consideration focused on the ground motions generated by the three events, including a...
Science
Engineering and Risk
The well-known statement "Earthquakes don't kill people, buildings do" highlights the need to make our communities more earthquake resilient. The impact of earthquakes on public safety and the national economy can be reduced through improvement of the built environment to resist earthquake effects such as ground shaking. Extending natural hazards science to risk involves (1) conducting research to...
