Liquefaction potential as a result of HayWired earthquake scenario mainshock (April 18, 2018) shaking in Alameda and Santa Clara counties, San Francisco Bay area, California

These data are a geospatial representation of liquefaction potential for the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data are the product of an analysis that created a detailed liquefaction probability map covering the northern Santa Clara County and western Alameda County areas.

Point locations for earthquakes M2.5 and greater in a two-year aftershock sequence resulting from the HayWired scenario earthquake mainshock (4/18/2018) in the San Francisco Bay area, California

This dataset represents the spatial locations of all modeled aftershocks magnitude 2.5 and greater resulting from the HayWired M7.0 mainshock occurring on April 18, 2018 along the Hayward Fault. The date/time, horizontal and vertical location, and sequence position is provided for each aftershock. The spatial extent covers 24 counties in whole or in part, corresponding to the modeled shaking exten

2017 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes

We produced a one-year 2017 seismic hazard forecast for the central and eastern United States from induced and natural earthquakes that replaces the one-year 2016 forecast, and evaluated the 2016 seismic hazard forecast to improve future assessments. The 2016 forecast indicated high seismic hazard (greater than 1% probability of damaging ground shaking in 1 year) in portions of Oklahoma/Kansas, th

Earthquake catalogs for the 2017 Central and Eastern U.S. short-term seismic hazard model

The U. S. Geological Survey (USGS) makes long-term seismic hazard forecasts that are used in building codes. The hazard models usually consider only natural seismicity; non-tectonic (man-made) earthquakes are excluded because they are transitory or too small. In the past decade, however, thousands of earthquakes related to underground fluid injection have occurred in the central and eastern U.S. (

Shakemap earthquake scenario: Building Seismic Safety Council 2014 Event Set (BSSC2014)

This is a catalog of earthquake scenarios, represented as ShakeMaps. A ShakeMap is a USGS product that facilitates communication of earthquake effects by portraying a map of the severity of shaking. Maps of shaking severity are provided in terms of macroseismic intensity, peak ground acceleration, peak ground velocity, and spectral accelerations (at 0.3, 1.0 and 3 sec oscillator periods).

3D point cloud data from laser scanning along the 2014 South Napa Earthquake surface rupture (2016)

Point cloud data in .laz format collected using a 3D laser scanner in Napa California in 2014 and 2015. Also included are aligned airborne laser scanner data from 2003 and 2014.

Liquefaction observations from ten earthquakes in the US, Japan, China, and Taiwan

These data include observations of liquefaction from ten earthquakes. The data are provided as a feature collection in a GeoJSON file format. Individual features are either points or polygons. Each feature has a single attribute called "earthquake" which gives the name and year of the earthquake associated with the liquefaction feature.

2016 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes

A one-year seismic hazard forecast for the Central and Eastern United States (CEUS), based on induced and natural earthquakes, has been produced by the U.S. Geological Survey. The model assumes that earthquake rates calculated from several different time windows will remain relatively stationary and can be used to forecast earthquake hazard and damage intensity for the year 2016. This assessment

Spreadsheet Applications

A simple text format suitable for loading data into spreadsheet applications. This is a good option for manual scientific analysis.


A flexible, extensible and modular XML representation of seismological data which is intended to cover a broad range of fields of application in modern seismology.

Programmatic Access

A well-structured format readily parsed by most programming languages. This is a good option for software developers wishing to use earthquake data.

Atom Syndication

A basic syndication format supported by a variety of feed readers. This is a good option for casually subscribing to earthquake information.
