摘要
利用ISC及中国台网的资料,研究了台湾地区的地震空间分布及地震机制解,并结合其他资料,讨论了菲律宾海板块与欧亚板块在台湾附近的相互作用方式及其对应力状态的影响。认为中国大陆东南沿海的主压应力方向与台湾大部的主压应力方向一致,但在远离台湾的地方,应力场的强度减弱,且方向改变,表明应力场来源于两板块的碰撞,但其影响范围有限。
The spacial distribution and fault plane solutions of earthquakes occurred in Taiwan Region have been studied by making use of the data from ISC and seismological network in China,the interacting pattern between the Philippine Sea plate and the Eurasian plate and their influence on the stress state in Taiwan and its vicinity are also discussed. It was found that the axis of principal compressive stress in southeast part of China is as the same as that in Taiwan, which shows that this stress state is also caused by the collision between the Philippine Sea plate and the Eurasian plate in Taiwan,but the influence of the collision on stress state is limited in certain areas.
