降雨干扰与短临震兆异常的识别方法

The Methods of Indentifing the Interference of Rianing with the Abnormal of Short-term Precursor

摘要:

通过对昆明地震台前兆观测资料的短临跟踪分析，发现短时间强暴降雨干扰引起的异常与地震前兆短临异常有相似特征，为了获取可靠的前兆变化信息，需要对观测资料进行降雨干扰排除，才能对类似异常变化做出客观的判断。

Abstract:

According to analysise the precursor observation data of Kunming Station, we find that the interference of rianing and the abnormal of short-term precursor have similar characteristics.In order to obtain reliable information of precursor change, it is necessary to eliminate the interference of raining from the observed data, so that we can make an objective judgment on the abnormal changes.
