根据震源机制解的大量结果,我们已经对东南沿海及邻近一些地区的构造应力场的特征及其成因进行了分析和探讨,认为:本区构造应力场的主压应力轴具有扇形分布的特征。具体地说,从台湾省(东经120°左右)沿纬度线往西,直至缅甸境内(东经95°左右),主压应力轴的取向明显表现出从东到西逐渐地由近东西向变化为南东向、南北向及至缅甸西部的南西向,有如一把褶扇张开成钝角的形状,称之为“扇形分布”。我们进一步认为,这种富于地区色彩
Based on a large number of results from focal mechanism solutions, we have analyzed and discussed the tectonic stress field characteristics and their genesis in the southeastern coastal areas and adjacent areas. We believe that the main compressive stress axis of the tectonic stress field in this area has the fan-shaped distribution. Specifically, from Taiwan Province (about 120 ° E) along the latitude line to the west and to the territory of Myanmar (about 95 ° E), the orientation of the principal compressive stress axis obviously shows a gradual change from east to west from near east-west to The south-east, north-south and south-west directions to the west of Myanmar resemble the “oblate-shaped” shape of a pleat that opens into an obtuse angle. We further believe that this rich regional color
