cleanstrain+
Software by  USGS  
<p>Cleanstrain+ is a program to process strainmeter data. This code will simultaneously estimate the tidal constituents, pressure admittance, offsets, rate changes, and other terms using least-squares but, importantly, incorporating the temporally correlated ...
FPFIT, FPPLOT and FPPAGE
Software by  USGS  
<p>FPFIT is a Fortran program that computes double-couple fault plane solutions from P-wave first motion data using a grid search method. The companion programs FPPLOT and FPPAGE plot the results on stereo nets for interactive viewing or for printing. There ...
Graizer-Kalkan (2015) Ground-Motion Prediction Equation
Software by  USGS  
<p>Graizer-Kalkan (2015) ground motion prediction equation (GMPE) is designed to predict peak-ground acceleration and 5% damped pseudo-spectral acceleration response ordinates for shallow-crustal continental earthquakes to be used in earthquake-engineering ...
HYPOINVERSE Earthquake Location
Software by  USGS  
<p>HYPOINVERSE2000 determines earthquake locations and magnitudes from seismic network data like first-arrival P and S arrival times, amplitudes and coda durations. The present versions HYPOINVERSE2000 (version 1.2 or 1.3) are in routine use by many networks. ...
MacRay
Software by  USGS  
<p>MacRay is a general purpose two-dimensional seismic ray-tracer for Macintosh. Originally written to trace rays through 2-dimensional p-wave models, MacRay has grown to support 2-d models defined in Vp, Vs and density. In addition to being able to model ...
OpenSHA
Software by  USGS  
<p>OpenSHA is an effort to develop object-oriented, web- &amp; GUI-enabled, open-source, and freely available code for conducting Seismic Hazard Analyses (SHA). Our goal is to provide a framework where any arbitrarily complex (e.g., physics based) earthquake-rupture ...
PQLX
Software by  USGS  
<p>PQLX is open-source software system for evaluating seismic station performance and data quality. The software consists of a server and client but also includes data extraction and manipulation tools. Given waveform data and instrument response files, PQLX ...
SLAMMER - Seismic Landslide Movement Modeled using Earthquake Records
Software by  USGS  
<p>SLAMMER is a Java program that facilitates performing a variety of sliding-block analyses to evaluate seismic slope performance. Functionalities include both rigorous and simplified analyses of rigid sliding blocks (i.e. Newmark analysis) and flexible sliding ...
Slick Package
Software by  USGS  
<p>The slick package uses fault slip data (either field observations or from focal mechamism) to find the stress tensor that best explains the observations. Inputs are the orientation and slip direction of a set of fault planes. Outputs are the oreintation ...
STATIC1D
Software by  USGS  
<p>These programs solve the equations of static equilibrium in a spherically layered isotropic medium using a decomposition into spheroidal and toroidal motions. For each spherical harmonic degree l and azimuthal order number m, the (l,m) response function ...
