Software
This is a subset of our downloadable software for earthquake research. USGS uses GitHub for all new software development, as well as open sourcing older software as time allows. For a comprehensive listing of all available software, see how our applications work, and to collaborate with us, please go to USGS GitHub.

Cleanstrain+ Cleanstrain+
Cleanstrain+ is a program to process strainmeter data.
CLUSTER2000 CLUSTER2000
CLUSTER2000 recognizes clusters in space-time in an earthquake catalog.
3D Focal Mechanisms 3D Focal Mechanisms
3D Focal Mechanisms is a tool for viewing earthquake focal mechanism symbols three dimensionally.
3D Velocity Modeling 3D Velocity Modeling
Fortran code (VMS compatible) for 3-D velocity model determination and hypocentral location with local earthquake data.
neic-glass3 neic-glass3
neic-glass3 is an open source and platform independent seismic event detection and association algorithm developed by the United States Geological Survey (USGS) National Earthquake Information Center (NEIC) and Caryl Erin Johnson, PhD, Introspective Systems LLC. This algorithm converts a time series of seismic phase arrival times, back azimuth estimates from array beams, and cross...
ShakeMap v4 Software ShakeMap v4 Software
ShakeMap v4 Software and Documentation
groundfailure groundfailure
This software is for calculating earthquake-induced ground failure hazard (i.e., landslide and liquefaction). These models are intended for regional or global scale applications, and are intended to be distributed in near-real-time, triggered by the Shakemaps.
SeismoTectonic Regime Earthquake Calculator (STREC) SeismoTectonic Regime Earthquake Calculator (STREC)
Automatically determines the earthquake type (subduction zone interface, active crustal shallow, stable continental region, etc.) and the earthquake focal mechanism.
landslides-mLS landslides-mLS
mLS is a function that estimates the landslide magnitude (mLS) from cutoff (smallest area that follows power law), beta (power-law exponent), and an array of areas derived from a landslide inventory following the methods of Tanyas and others (in prep). The function plots the best power-law fit for the medium and large landslides and the frequency-area distribution of the analyzed...
landslides-metadata landslides-metadata
Automate production of metadata following the USGS geospatial metadata format.
nshmp-haz-v1 nshmp-haz-v1
U.S. Geological Survey (USGS) National Seismic Hazard Mapping Project (NSHMP) code for performing probabilistic seismic hazard (PSHA) and related analyses. These codes are intended for use with seismic hazard models developed by the NSHMP for the U.S. and its territories.
Point-source to finite-fault distance conversions Point-source to finite-fault distance conversions
Produce approximated finite fault distances and variance corrections given point source information, e.g., Repi (epcentral distance) to Rrup (rupture distance).
