1. 3D Visualization of Earthquake Focal Mechanisms Using ArcScene [USGS_DS_2007_241]
We created a new tool, 3D Focal Mechanisms (3DFM), for viewing earthquake focal mechanism symbols three dimensionally. This tool operates within the Environmental Systems Research Institute (ESRI®) ...


2. Earthquake Information Distribution System (EIDS) [USGS_EIDS]
The Earthquake Information Distribution System (EIDS) provides a method for receiving earthquake data over the Internet in near-real time. EIDS replaces the Quake Data Distribution System (QDDS) and ...


3. STATIC1D - Program for Solving the Equations of Static Equilibrium in a Spherically Layered Isotropic Medium [USGS_STATIC1D]
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 ...


4. Slick Package - Stress Inversion from Slip Data [USGS_SLICK_PACKAGE]
The slick package uses fault slip data (either field observations or from focal mechanism) to find the stress tensor that best explains the observations. Inputs are the orientation and slip direction ...


5. VISCO1D - A Program Package to Calculate Quasi-Static Deformation on a Layered Spherical Earth [USGS_VISCO1D]
VISCO1D-v3 is a program package to calculate quasi-static deformation on a layered spherical Earth from a specified input source (fault plane parameters) at specified points on the surface or at depth. ...


6. Earthquake Strains and Rotations Software [USGS_strainz17]
Strainz17.m is a MATLAB-language function for deriving the best-fitting uniform strain tensor and rigid body rotation as functions of time, based on ground displacement or velocity recordings made ...


7. ShakeCast - An Application for Automating ShakeMap Delivery to Critical Users and Facilitating Notification of Shaking Levels [USGS_ShakeCast]
ShakeCast is a freely available, post-earthquake situational awareness application that automatically retrieves earthquake shaking data from ShakeMap, compares intensity measures against users' facilities, ...


8. HASH - Software for Computing Double-Couple Earthquake Focal Mechanisms [USGS_HASH]
HASH is a Fortran 77 code that computes double-couple earthquake focal mechanisms from P-wave first motion polarity observations, and optionally S/P amplitude ratios. HASH is designed to produce stable ...
