乌海4.6级地震前断层气CO₂异常特征分析

摘要: 通过对乌海4.6级地震前CO₂观测值处理,并应用"九五"攻关研究新成果中多种数学方法进行异常提取和分析,得到了滤波、比值、单点速率等分析计算结果,有效地在震前1个月提取到地震短临前兆异常,说明CO₂这种新方法能在地震短临预报中发挥较好的作用。

Abstract: through processing the data of CO₂ before Wuhai M4.6 earthquake and using the new methods obtained in "Ninth five years project", we got some results, such as filtering, ratio, single point rate etc..Some imminent anomalies were picked up effectively one month before the earthquake.It shows the method of CO₂ can be very useful in imminent prediction.
