| 摘 要： | 本文分析了东南沿海地区70个震源机制结果, 得到本区现代构造应力场的主压应力轴具有扇形分布的特征.东、西两部的震源错动方式截然相反.根据亚洲东南部地块的震源应力场资料, 认为本区应力场及其特征可以从太平洋板块和印度洋板块相对于欧亚板块的运动得到合理的成因解释.

| Abstract: | The analysis of focal mechanism for 70 events in the SE coastal China indicates that the principal compression axes of the recent stress field is characterized by a fan-shaped distribution. The nature of focal dislocation of the east portion of the coastal region is quite different from that of the West.Based on the stress field data of Southeast Asia from earthquake focal mechanism analysis, it seems clear that the stress field, as well as its character, may reasonably be explained by the movement of the Pacific and the Indian Ocean plates relative to the Eurasian Plate. |
