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 ...
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 ...
