Seismotectonics of the Eastern Margin of the Australia Plate

The Australia-Pacific margin is an intensely active plate boundary that produces some of the world's most powerful earthquakes, tsunamis, and volcanic eruptions. Explore this interactive geonarrative (Esri storymap).

Seismogram Displays and Information

Real-time seismograms from Global Seismographic Network (GSN) and Advanced National Seismic System (ANSS) stations, and station information for both.

Cascadia Subduction Zone Database

A compilation of published datasets relevant to Cascadia subduction zone earthquake hazards and tectonics.

Seismic Design Data Web Services

Web services produced by the U.S. Geological Survey for calculating parameter values from various seismic design reference documents.

Cone Penetration Testing (CPT) Data

Cone Penetration Testing (CPT) is used to identify subsurface conditions in the upper 100 ft of the subsurface.

Interactive U.S. Fault Map

The Quaternary Fault and Fold Database of the United States database contains information on faults and associated folds in the United States that demonstrate geological evidence of coseismic surface deformation in large earthquakes during the past 1.6 million years (Myr).

Earthquake Scenarios

A scenario represents one realization of a potential future earthquake by assuming a particular magnitude, location, and fault-rupture geometry and estimating shaking using a variety of strategies.

Generate a SLAB Model

This web application is used for generating a 3D slab model following the procedure of Hayes et al., 2018.

SLAB2.0 Interactive Map

Subduction zones are home to the most seismically active faults on the planet. The shallow megathrust interface of subduction zones host our largest earthquakes, and are the only faults capable of M9+ ruptures.

National Strong Motion Data

Processed strong-motion records of engineering interest are available at the Center for Engineering Strong Motion Data (CESMD).

U.S. Vs30 Map Viewer

Vs30, the time-averaged shear-wave velocity (Vs) in the upper 30 meters, is a key index adopted by the earthquake engineering community to account for seismic site conditions. USGS has compiled measured VS30 funded by the USGS and other governmental agencies for 4389 sites in the United States.
