华北地区地震条带的统计分析

Statistical Analysis of seismic Bands in North China

该文对华北地区1970-2017年的地震条带进行识别清理研究,结果表明,华北地区M_S≥5地震前出现条带的比例约为50%,且华北地区M_L≥3.0地震条带的持续时间、长度、起始震级均与主震震级存在一定的线性正相关关系。说明可将地震条带作为地震预测的依据之一,并结合其他方面的资料来综合做出未来震情的判定。

The research on the identification and clearing of seismic bands in North China from 1970 to 2017 are carried out in this paper,and the results show that the proportion of occurrence of seismic bands before M_S≥5)earthquakes in North China is about50%,and the duration,length and initial magnitude of M_L≥3.0 seismic bands in North China are linearly and positively correlated with the magnitude of the main earthquake.Seismic bands can be used as one of the bases of earthquake prediction,and the trend of future earthquake situation can be judged synthetically by combining other data.
