1969年渤海7.4级大震前后的区域地震活动图象
|
摘要
分析与总结了 1969年渤海 M7.4大震前后地震活动图象特征 ,包括大震序列的时空分布及前兆地震活动图象特征、大震等距迁移、主要间隔期缩短、共轭断层蠕滑、小震成带、诱发前震现象 ,地震触发响应系数异常十分显著。指出地震相互作用和自组织性为中长期地震预报提供了可能。
Seismicity pattern characteristics before and after the Bohai M7.4 earthquake of 1969 are analyzed,including time-space distribution of large earthquake series,precursory seismicity patterns characteristics,equidistant migration of large earthquakes,chief interval shortening,conjugate faults'creep slip,microearthquakes zonation,phenomena of induced foreshock.The anomaly of earthquake triggering coefficient is extremely obvious.Since we pointed out the character of earthquakes' interaction and self-organization,it makes long term earthquake prediction possible.
