Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

A Site Response Module Toolbox for the Broadband Platform: Implementation and Verification

Published August 16, 2019, SCEC Contribution #9906, 2019 SCEC Annual Meeting Poster #010

We present a site module toolbox for the SCEC broadband platform, which synthesizes individual tools and libraries that we developed over the past years, supported in part by SCEC. Our open-source Python library, PySeismoSoil, can be used to compute: (1) synthetic empirical adjustments for nonlinear site response on BBP ground motion synthetics in the Western United States, (2) site-specific (wave-propagation based) nonlinear site response, and (3) randomized 1D shear wave velocity profiles. Each component of the module has been previously verified and validated as part of the international benchmark effort for nonlinear site response code, PRENOLIN (Regnier et al., 2018). The module toolbox requires the same input as the site factors currently implemented on the BBP, thus providing complete backward compatibility. Beyond the BBP, the module can be used as a standalone toolbox for site response analyses intended for seismic hazard estimation and earthquake engineering design procedures.
