Near-Source Ground-Motion Behavoir of the June 20, 1990 Earthquake

这笔赠款将通过SGER资助急需的支持 分析1990年6月20日北方地震的程序 伊朗 首席研究员获得了一组独特的数据 33个峰值地面加速度的测量记录， 100公里的源头。 这个数据集是独一无二的，因为 从该国获得技术信息的速度非常缓慢， 对旅行和实地调查的限制， 伊朗 伊朗以外的科学界渴望学习 关于近距离产生的地面运动的行为， 震源区和从这次地震中吸取的教训。 峰值地面加速度随距离的衰减， 方向将进行分析，并与其他地区的比较， 世界 这项研究是国家 减少地震灾害计划。

This grant will fund urgently needed support through the SGER program to analyze the June 20, 1990, earthquake in northern Iran. The principal investigator has obtained a unique data set of 33 measurements of peak ground acceleration recorded within 100 km of the source. This data set is unique because the flow of technical information from that country is extremely slow due to restrictions imposed on travel and field investigation in Iran. The scientific community outside Iran is eager to learn about the behavior of the ground-motion generated in the near- source region and the lessons to be learned from this earthquake. The attenuation of peak ground acceleration with distance and orientation will be analyzed and compared with other regions of the world. This research is a component of the National Earthquake Hazard Reduction Program.
