甘肃定西6.6级地震前昔阳地震台SSQ-2I水平摆异常特征
About anomaly characteristics of SSQ-2 I horizontal pendulum at Xiyang Seismic Station before Dingxi M 6.6 earthquake in Gansu Province
摘要
Abstract
The observations of SSQ-2I digital horizontal pendulum at Xiyang Seismic Station appeared tendency variation on July 9, before Minxian and Zhangxian M 6.6 earthquake in Gansu Province, on July 22, 2013. The anomaly determination is conducted by analyzing the characteristics of abnormal data before the earthquake. And using precursor vector, comparative analysis of multiple data, auxiliary measurement analysis, comparing with data of follow-up Minxian and Zhangxian M 4.0 earthquake in Gansu Province and other related research work, it is believed that the abnormal change of the data before the Dingxi M 6.6 earthquake in Gansu Province is in correspondence with the earthquake.关键词
