| 摘 要： | 岫岩－海城５．６级地震前半年内，先后出现了义县地电阻率，台安地电阻率异常变化，这些异常信息也是该次地震成功预报和重要前兆判据之一。研究认为，震前的义县、台安地电阻异常属于“场兆”，而临震前的电磁辐射信息是“源兆”。同时，电阻率的异常变化显示出向震中迁移的特点。

| Abstract: | There are resistivity anomalous variation successively in Yixian and Taian about half a year prior to Xiuyan-Haicheng Ms5.6 earthquake, it is one of the key precursory criterions for predicting the earthquake. We have studied the matters and obtained the results of Yixian and Taian resistivity anomaly variation is a seismic fieldprecursor, the prequalce electromagnetic radiation is a source-precursor and the anomaly variation of resistivity moves towards the epicentre. |
