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.

Latest Pleistocene to 19th-century earthquakes on bending-moment reverse faults of the Seattle fault zone, Washington Latest Pleistocene to 19th-century earthquakes on bending-moment reverse faults of the Seattle fault zone, Washington
Fault-related folds and their associated secondary faults play a critical yet often underrecognized role in accommodating strain and generating earthquakes in active fold-and-thrust belts. In the Seattle fault zone (SFZ), Washington, USA, we present new paleoseismic, geomorphic, and geophysical evidence for late Pleistocene and Holocene earthquakes on shallow, south-dipping secondary...
An entropic explanation for Gutenberg-Richter scaling An entropic explanation for Gutenberg-Richter scaling
We develop a simple explanation for Gutenberg-Richter (G-R) size scaling of earthquakes on a single fault. We discretize the fault and consider all possible contiguous ruptures at that level of discretization. In this static model, we assume that slip scales with rupture length, and that the rupture rates at each point along the fault are consistent with an a priori long-term slip rate...
Rapid characterization of the 2025 Mw 8.8 Kamchatka, Russia earthquake Rapid characterization of the 2025 Mw 8.8 Kamchatka, Russia earthquake
The 29 July 2025 Mw 8.8 Kamchatka, Russia, earthquake was the sixth largest instrumentally recorded earthquake. This event was seismically well observed at regional and teleseismic distances, but publicly available near‐source data were sparse at the time of the event, presenting unique challenges for rapid source and impact characterization. The U.S. Geological Survey (USGS) National...
Science
Earthquake Sequence Product
The USGS earthquake Sequence Product aims to identify and describe earthquakes that are clustered in space and time as “sequences.” Its overarching goal is to provide simple contextual information regarding the spatial and temporal interconnection of earthquakes.
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...
