山东地区震群活动与周围地区中强地震的关系

RELATIONSHIP BETWEEN EARTHQUAKE SWARMS IN SHANDONG AREA AND MID-STRONG EARTHQUAKES IN ITS SURROUNDING AREA

  • 摘要: 分析了山东地区1970年以来的震群和地震小序列的群体活动与周围地区中强地震的关系,发现震群和小序列的群体活动对周围地区的中强地震有震兆意义。统计分析了它们之间的关系,给出了山东及其周围地区中强地震发生前震群和小序列群体活动的异常指标,该指标对其周边地区中强以上地震的年度和中短期预测有实用意义。

     

    Abstract: The relationship between the activities of earthquake swarms and small earthquake series in Shandong area and mid-strong earthquakes in its surrounding area since 1970is analyzed.The research shows that the activities of earthquake swarms and small earthquake series have seismic precursor significance to mid-strong earthquakes.The relations between them are statistical analyzed,and the abnormal indexes that have practical significance to annual or mid-short term prediction of mid-strong earthquakes in surrounding area are given.
