摘要
利用测震学时空扫描方法,结合地质活动构造,对胶东及北部海域地震活动特征及近期地震活动趋势进行了分析研究,结果表明:该区4~5级地震有5a左右周期性,本区中等地震或外围强震前,地震活动性参数出现异常现象;据统计预测及地震学异常认为,该区近期仍有发生5级左右地震的可能。
By means of seismometry time-space scanning and active structurss analyses,the seismic activity and tendency in the near future in the Jiaodong and its in shore area are studiedThe result shows that earthquakes (4≤Ms≤5) have a cycle of about 5 yearsPrior to medium earthquakes in this area and strong earthquakes on the periphery,seismicty parameters become abnormallyBy analysing the statistics and seismic anomolies,it is inferred that an earthquake about M5 will occur in this area in the near future
