| 摘 要： | 分析了大华北浅源地震与日本海西部及我国东北深震的关系,认为本世纪来日本海西部—我国东北深震经历了5个相对活跃期,大华北各地震区相应经历这5个活跃期的影响期。根据大华北M≧6级浅源地震与深震活动的相关性,建立了太平洋板块楔形俯冲带端部重大深震事件导致大华北浅源M≧6级地震发生的板块俯冲模型,应变波传播速度约94km/年,地表视速度约100km/年。重大深震事件突出、模型稳定性强,预测实验表明模型公式可做大华北地震监测参考。用本模型可以解释浅源地震迁移、各地震区地震与深震活动相关等现象。

| Abstract: | The relation between the shallow earthquakes in North China and the deep focus earthquakes in western part of Sea of Japan and in Northeastern China has been analyzed in the paper. We consider that the deep earthquakes in above mentioned seismic area has undergone five relative active periods in this century,and the active periods correspondently have influence on the shallow shocks activity in North China. According to the correlativity between shallow earthquakes of M>=6 in North China and deep shocks,the subducting plate model has set up which results from great deep earthquakes in end of Pacific subducting plate which leads to the shallow shocks in North China. The propagation velocity of strain wave is about 94kin/year. and the apparent velocity is on the order of 100km/yeap. Using this model can explain earthquake migration, correlative phenomena relating to shallow shocks and deep earthquake et al. |
