摘　　要：中国是一个多地震的国家,以地震多、震级大、损失惨重为特征。介绍了西太平洋与欧亚大陆间的洋-陆俯冲带型地震;印度次大陆与喜马拉雅陆-陆碰撞型地震和华北地幔亚热柱拆离滑脱型地震等3种地震基本类型,并侧重探讨了华北地幔亚热柱外围拆离滑脱带型地震的发震构造、形成机制和地震模型。China is a multi-state earthquake country,characterized by multi earthquake,large magnitude and high loss.This paper introduces the ocean-land subduction zone-type earthquake between the Western Pacific and the Eurasian continent,collision-type earthquakes between the Indian subcontinent and the Himalayan,as well as collision-type earthquakes of detachment-type earthquakes in sub-mantle plume of North China continental,they are three basic types of earthquake, and focuses on seismogenic structure of peripheral-type earthquake surrounding detachment sub-mantle plume in the North China,formation mechanism and seismic models.
