摘要
根据中强地震前前兆观测资料的异常特征和各种前兆异常可信度的差异,考虑到单项观测数据和多项观测数据的相互联系,提出了用综合参数S描述多项前兆观测数据整体变化。结果表明,与单项前兆观测数据比较,综合参数S有变化平稳、震前异常反应明显等优点,可以作为地震预报实践中识别前兆异常的方法之一。
Based on the anomaly features of precursor data observed before medium-strong earthquakes and the difference of confidence of various precursor anomaly, considering the relationship between the observation data from single way and the observation data from various ways, synthetical parameter S which can be used to describe the whole changes of various precursor observation data is proposed. The research results shows that the synthetical parameter S,compared with the observation data from single way ,have some advantages of changing smoothly and having obvious anomalies before earthquakes. It can be used as one of the methods which can identify precursor anomalies in practice of earthquake prediction.
