ABSTRACT

This paper provides a review of the procedure of customizing ShakeMap V4.0 provided by U.S. Geological Survey based on seismic characteristics of Iran. Selecting appropriate GMPEs, adopting a suitable spatial cross-correlation model and proper modeling of site condition are important factors in the context of the ShakeMap algorithm. The present paper technically reviews the aforementioned parameters. In addition, a number of statistical tests were performed to provide the optimum configuration. The initial prototype of the configured ShakeMap has been used to provide the ground motion shaking map in the aftermath of a great earthquake in Iran (since Aug, 2021).

摘要

本文根据伊朗的地震特点，对美国地质调查局提供的ShakeMap V4.0定制程序进行了回顾。选择合适的 GMPE、采用合适的空间互相关模型和适当的场地条件建模是 ShakeMap 算法上下文中的重要因素。本文从技术上回顾了上述参数。此外，还进行了许多统计测试以提供最佳配置。配置的 ShakeMap 的初始原型已用于提供伊朗大地震后（自 2021 年 8 月起）的地震动图。
