Point-Source Load Estimation Tool (PSLoadEsT) Point-Source Load Estimation Tool (PSLoadEsT)

Software for generating reproducible load calculations for point source dischargers. Includes features to manage common data challenges such as duplicates, incompatible input tables, and missing nutrient concentration or effluent flow data.

Slab2 Slab2

A three-dimensional compilation of global subduction geometries, separated into regional models for each major subduction zone.

STATIC1D STATIC1D

These programs solve the equations of static equilibrium in a spherically layered isotropic medium using a decomposition into spheroidal and toroidal motions.

strainz17: Earthquake Strains and Rotations strainz17: Earthquake Strains and Rotations

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 on an array of sensors.

PS2FF PS2FF

Produce approximated finite fault distances and variance corrections given point source information, for example, Repi (epcentral distance) to Rjb (Joyner-Boore distance) or Rrup (closest distance to rupture).
