摘要
依据六合体应变异常,在2006年7月26日安徽定远4.2级地震和2007年5月6日江苏响水ML4.0地震前,我们提出了短临预测意见。预测实践表明,根据六合体应变异常提出11~24天时间段在450km范围内有发生5.5级左右地震、在200km范围内有发生4.0级左右地震可能性的预测意见有一定的科学性,还有可能根据异常最低点出现时间提出3天之内发震的临震预测意见,实践还表明依据六合体应变异常所预测的震中位置和震级会有较大误差。反思两次地震预测实践,我们有依据期望通过每一点进步来挑战地震预报难题,目前力求能在震前有所察觉,提前向领导部门打个招呼。
According to the anomalies of strain meter observation at Liuhe seismic station, we made predictions before Anhui-Dingyuan earthquake with MS4.2 on July 26, 2006 and Jiangsu-Xiangshui earthquake with ML4.0 on May 6, 2007. Practice has shown that the prediction of about MS5.5 earthquake within 450 km, or about MS4.0 earthquake within 200 km before 11 to 24 days of earthquake occurrence may be possible. We can also make short-term prediction of earthquake within 3 days according to the lowest point of anomaly, but the prediction of epicenter and magnitude are inaccuracy. Through practice, we will make progress in earthquake predictions step by step.
