Description
Summary:The main objective of this article is to assess a set of candidate ground motion models in the Zagros region of Iran. The candidate models were chosen from three categories: local models that were developed based on the local data, regional models corresponding to Europe and Middle East data sets, and finally NGA (Next Generation Attenuation) models. Two different statistical approaches were applied for evaluation of these models, the first being the "likelihood" method, and the second the average "log-likelihood" method (LH and LLH). One of the most significant results of this study is that local ground motion models show more consistency with the recorded data than do NGA models.
