Observational Studies of Induced Earthquakes
In response to sudden changes in seismicity that are potentially induced by human activity, the USGS may deploy temporary seismic stations to better understand the earthquakes. These deployments typically consist of 2-15 seismometers placed in the immediate vicinity of the seismicity.
Improving Earthquake Monitoring with Deep Learning
Release Date: MARCH 12, 2021 On January 20, 2021 at 8:32am light shaking interrupted breakfast customers at a local coffee shop south of downtown Los Angeles, California. Everyone paused briefly while they waited to see if it was going to stop… or start shaking harder.

SLAB2 - A Comprehensive Subduction Zone Geometry Model
Data for subduction zone slab geometry.
Monitoring for Subduction Zone Science
Subduction zone monitoring requires monitoring networks that are operated collaboratively for years to decades. Such a sustained activity requires leadership by a Federal agency like the USGS with the support of its partners.
National Seismic Hazard Model Project Steering Committee
The National Seismic Hazard Model Project (NSHMP) Steering Committee is a panel of nine subject matter experts that meets routinely with the NSHMP to discuss and review inputs to the National Seismic Hazard Models (NSHMs).
3-D Geologic and Seismic Velocity Models of the San Francisco Bay Region
The USGS 3-D Geologic and Seismic Velocity Models of the San Francisco Bay region provide a three-dimensional view of the geologic structure and physical properties of the region down to a depth of 45 km (28 miles). Construction of this 3D Bay Area model has been a joint effort of the USGS Earthquake Hazards Program and the USGS National Cooperative Geologic Mapping Program.
Auroras and Earthquakes: Strange Companions
Release Date: JULY 6, 2020 In 1722 and 1723 a London clockmaker, George Graham, observed daily and consistent variations on one of his instruments, a “Needle upon the Pin” (a compass), for which he had no explanation. Swedish scientists obtained some of Graham’s instruments to record what is now known to be the variations in Earth’s magnetic field. In 1741, they noticed a significant deflection of...
