摘要:
利用青海地区定点形变观测数据,分析了2016年1月21日青海门源6.4级地震前的前兆异常现象,并讨论了异常的信度。结果表明,门源地震前青海地区部分倾斜和应变观测数据出现了较为可靠的中短期地震前兆异常变化,异常出现时间在震前5个月至1年,主要表现为破年变和趋势转折类异常。
Abstract:
Based on the deformation observation data of fixed points in Qinghai area,we analyze the precursor anomalies of digital deformation and the anomalies reliability before Menyuan MS6.4 earthquake on Jan.21,2016. The results showed that there existed medium-short-term anomalies with high reliability in part of tilt and strain observation data in Qinghai area before the earthquake. The precursor anomalies mainly presented broken annual variation and tendency change in 5 months to 1 year before earthquake.
