Earthquake Strains and Rotations Software
Entry ID: USGS_strainz17


Summary
Abstract: 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. Strainz17.m implements the theory in Spudich et al. (J. Geophys. Res., 1995) and Spudich and Fletcher (Bull. Seismol. Soc. Am., 2008). In addition to the strainz1717.m function, the downloadable file provides sample input and output data, and it provides functions for running the sample test cases.
