Standard Rupture Format (SRF) is a file format defined by Robert Graves (USGS) intended to facilitate exchange of rupture descriptions between scientists.

Version 2 released in 2015

Version 1 released in 2010

CyberShake Data Web Service - SRF Retrieval

One of the requirements for the 2010 USEIT intern class was to create a Standard Rupture Format (SRF) browser plugin for SCEC-VDO. This required a tool to retrieve SRF files from the CyberShake database. The 'GETCSSRF' web service was written to allow users to retrieve the SRF files from the CyberShake database.

This web service was written as a Python application. The service takes a set of arguments to select the desired file out of the CyberShake database and returns the contents of the SRF file is found. The service also supports an option to list the set of supported CyberShake Earthquake Rupture Forecast and Rupture Variation Scenario versions.
