Probabilistic Forecasting of Earthquakes, Tsunamis, and Earthquake Effects in the Coastal Zone
The nation's coastlines are vulnerable to the interrelated hazards posed by earthquakes, landslides, and tsunamis. In the marine environment these events often occur in concert, and distant triggers can cause severe local effects, making the issue global in scope. As the population continues to migrate toward the coastlines, the social impacts of these hazards are expected to grow.
Coastal and Marine Geohazards of the U.S. West Coast and Alaska
Coastal and marine geohazards are sudden and extreme events beneath the ocean that threaten coastal populations. Such underwater hazards include earthquakes, volcanic eruptions, landslides, and tsunamis.

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 .
Tsunami and Earthquake Research
Here you will find general information on the science behind tsunami generation, computer animations of tsunamis, and summaries of past field studies.
