Overview

All UCERF3 materials, from inversions to solutions to earthquake rupture forecasts, were created using OpenSHA. This page provides support for those looking to use the UCERF3 model, both from within OpenSHA and without.

UCERF3 Fault System Solutions

This is the appropriate starting point for those wishing to use the UCERF3 model outside OpenSHA. A Fault System Solution is a *.zip file that contains all information relevant to using UCERF3 as an earthquake source model. When using these files it is important to be aware of the following:

  • Gridded seismicity (or background) sources are composed of up to two Magnitude frequency distributions (MFDs) at each 0.1° x 0.1° spaced grid node. One is "associated" (as in small earthquake associated with any faults in a grid cell) and the other is "unassociated" (as in independent of any faults). These two MFDs must be added to obtain the total off-fault, gridded, or background seismicity source rate.

UCERF3 ERFs

This page provides details on using UCERF3 solutions within the OpenSHA framework as earthquake rupture forecasts (ERFs).

UCERF3 Figure Reproducibility

This page provides instructions on how to reproduce all figures that accompany the UCERF3 USGS Open-File Report and BSSA publication.

Running UCERF3 Inversions
