| 摘 要： | 通过对天水地区监测和收集的2008年前兆资料整理分析,在汶川8.0级地震前,天水电磁和地下流体等前兆测项均有明显短临异常,同震效应突出。本文在回溯总结这些异常的基础上提出震情分析的思路和问题探讨,对今后本地区的地震趋势判断提供参考。

| Abstract: | Through data collection and compilation of all stations in Tianshui area and one station of Beichuan county Sichuan province, this paper retrospectively analyzed the anomalies of resistivity and ground fluid and found obvious preseismic anomalies in short term to imminent term and coseismic anomalies of Wenchuan MS8.0 earthquake. Based on above works, the future earthquake situation after Wenchuan was discussed, which can be as reference for local earthquake monitoring and earthquake hazard mitigation of Tianshui area. |
