摘要
地应力观测是目前我国进行地震前兆观测的重要手段之一。利用汶川地震前刘家峡台地应力观测资料,通过分析,获得汶川地震前刘家峡台地应力观测资料的异常特征,解释了汶川地震的震源机制。对现有地震预测方法中存在的一些问题进行了讨论并提出了一些解决办法。
Ground stress observation is one of important means in monitoring earthquake prediction. The observation data of Liujiaxia before Wenchuan earthquake is analyzed, and some anomalous seismic characteristics before Wenchuan earthquake and its focal mechanism are discussed. Some problems in the earthquake prediction and the countermeasures are pointed out.
