Natural Hazards
Every year in the United States, natural hazard events threaten lives and livelihoods, resulting in deaths and billions of dollars in damage. Access the scientific data collected from monitoring, assessing, and conducting targeted research on a wide range of natural hazards.
Ash3D provides forecasts of ash clouds and ashfall.
Ash 3D is a three-dimensional simulation of volcanic-ash dispersion that uses time-varying wind fields and other meteorological properties to calculate where airborne ash is transported under current or historical atmospheric conditions
Cliff Feature Delineation Tool and Baseline Builder
The Cliff Feature Delineation Tool scans digital elevation models (DEM) to delineate features on seacliffs like the cliff top, midline, toe, and convexities/concavities on the cliff face, outputting linear features as polylines and point shapefiles.
Slab2
A three-dimensional compilation of global subduction geometries, separated into regional models for each major subduction zone.
SLAMMER - Seismic Landslide Movement Modeled using Earthquake Records
SLAMMER is a Java program that facilitates performing a variety of sliding-block analyses to evaluate seismic slope performance.
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.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
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).
SATSI
SATSI (Spatial And Temporal Stress Inversion) is a modified version of Michael's (JGR 1984, 1987) code that inverts focal mechanism data for a spatially and/or temporally varying stress field.
Quakeml
A uniform ANSS standard for seismic parametric data.
PQLX: A Software Tool to Evaluate Seismic Station Performance
PQLX is open-source software system for evaluating seismic station performance and data quality.
MacRay
MacRay is a general purpose two-dimensional seismic ray-tracer for Macintosh.
MacR1D
MacR1D is a one-dimensional seismic travel-time calculator for Macintosh.
