In wltcwpf/GMPE: A pacakge of commonly used Ground Motion Prediction Equations (GMPE)

GMPE

The pacakge is developed for research use. This package contains commonly used Ground Motion Prediction Equations (GMPE). It includes five NGA-West2 Models (ASK14, BSSA14, CB14, CY14, and I14) for crustal earthquakes; and four (BC Hyrdo 2011 + 2019, Zhao et al 2016, Parker et al 2020 NGA-Subduction) for subduction earthquakes, and one NGA Central and Eastern North America (CENA) Model. A shallow crustal or upper mantle earthquake model by Zhao et al (2017) is also included.

Update on 10/05/2023: NGA CENA code was adapted and optimized from NHR3 Products: Ground Motion Tools for GMM on reference site condition (Vs30 = 3000 m/s) and a Python code written by Tristan Buckreis at UCLA for site amplification models (Stewart et al., 2020; and Hashash et al.,2020)

Update on 11/13/2023: I updated BSSA14 model by including an option of incorporating CA subregional anelastic attenuation model (Buckreis, Stewart, Brandenberg, and Wang, 2023, Subregional Anelastic Attenuation Model for California)
