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.

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).

Latest Earthquakes

Latest earthquakes map and list (default view is past 24 hours, M2.5+). Tap/click on "gear icon" for options and settings.
 

Earthquake Notifications, Feeds, and Web Services

Know about earthquakes just after they happen in real-time via txt message, email, or social media. Plus, get everything you might need to add these earthquake alerts into your own web applications.

Did You Feel It?

Did You Feel It? (DYFI) collects information from people who felt an earthquake and creates a shaking intensity map. Visit the Web Tool to report your experience with an earthquake or to see the shaking intensity map created by the felt reports.

Search Earthquake Catalog

Find past earthquakes and earthquake lists from specific locations and time windows. Results available in a variety of formats.
