This research will analyze recordings that were made by chance from an IRIS network installed in the northern Caucasus which recorded the Apıril 29, 1991 Ms=7.2 Ossetian earthquake in the Soviet Union. Seven of the stations were transferred to the aftershock area by May 15 and recorded more than 500 events. This is a rare opportunity to study an intercontinental earthquake that is related to the continent-continent collision of the Arabian and Eurasian plates. This research is a component of the National Earthquake Hazard Reduction Program.

这项研究将分析从北高加索地区安装的虹膜网络偶然进行的录音，该网络记录了Apıril29，1991 MS = 7.2 Ossetian在苏联的地震。 5月15日之前将其中七个车站转移到了余震区，并记录了500多个事件。这是研究与阿拉伯和欧亚板块大陆相互碰撞有关的洲际地震的难得的机会。这项研究是国家地震危害计划的组成部分。
