This repository provides MATLAB codes to implement a set of consistent GMMs for Iran. The GMMs are developed to predict three components of ground motions, namely, horizontal, vertical, and also vertical-to-horizontal ratio of PGA, PGV, and 5%-damped spectral acceleration (0.01–10 s). Each GMM set (i.e., H, V, or V/H) includes four consistent models based on different distance measures; Repi- and Rhyp-based model are associated with point-source, and RJB- and Rrup-based models are associated with finite-fault sources.
