基于地震前兆台站观测的异常信息预测强震发生地点,是地震预测研究的薄弱环节之一。例如,在日常震情分析预报中,通常将多种异常现象的相对集中区作为未来可能的强震震中所在区域。但在实际操作中,面临诸多困难和较大的不确定性。关于汶川地震和玉树地震的预测结果说明:我们根据地震前兆台站 Predicting the location of a strong earthquake based on the anomaly information of the observation of the earthquake precursor station is one of the weak points in the earthquake prediction research. For example, in the analysis and prediction of daily earthquake conditions, relatively concentrated areas of various anomalies are usually used as the area where the possible strong earthquake epicenter is located in the future. However, in actual operation, it faces many difficulties and great uncertainties. The prediction results of the Wenchuan earthquake and the Yushu earthquake show that we are based on the earthquake precursor station
