摘要
根据ISC1964～1996年震源深度分布资料,提出西太平洋板块在日本本州和菲律宾群岛的棉兰老岛一带有两个触角和欧亚板块直接相接,菲律宾板块东缘与西太平洋板块为依托关系,菲律宾板块西缘和欧亚板块为碰撞关系。从1900年以来的深震资料分析,东北深震活动分别对中国东北、华北的地震有一定影响,对台湾地区影响不大。结合GPS结果分析,1900年以来华北块体的地震活动可能与印度板块运动有关。
The distributions of focal depth in western Pacific were studied by ISC from 1964～1996 in this paper.We put forward two plates in Houshu of Japan and Mianland laodao of Philippines are in touch with western Pacific plate.They are supporting relation between the eastern side of Philippines plate and the western side of Pacific Plate,the colliding relation between western side of Philippines plate and EuropeAsia plate in Taiwan Region.The deep earthquake activity in Northeast is relative with the earthquake activity in northeast and North China, but not Taiwan,and the earthquake activity of North China may be relative with movement of India plate since 1900.
