【摘要】 根据 MDCB-5型临震信息监测仪记录到的某一地震临震异常幅度 (电压值 )、持续时间 (天数 )与岩石破裂、地震发生、地震波能量释放的相关性 ,从地震发生的物理基础出发 ,推导出了 2个计算未来震级大小的理论公式。使用 44天的监测数据对该期间发生的 5次6级以上地震的震级进行了计算 ,在相应的震中距范围内计算的震级与实际发生的震级误差小于 0 .5级 ,初步说明了该方法应用于实际地震预报具有一定的参考价值更多还原

【Abstract】 According to the relationship between amplitude of impending earthquake anomalies (voltage value) and duration time (day) of an earthquake recorded by model MDCB-5 instruments for monitoring impending earthquake data and rock rupture, earthquake occurrence and seismic wave energy release,two theoretical formulas of calculating magnitude of future earthquakes have been derived on the physical basis of earthquake occurrence.Making use of 44-day recorded data,the magnitude of five earthquakes with M>6 occurring in the 44 days was calculated,the error between calculated magnitude and actural magnitude is less than 0 5 within the range of relative epicentral distance,indicating that the method is of certain reference value to actual earthquake prediction.更多还原
