| Abstract: | Based on the result of two triangtilation surveys done respectively in 1956 and 1967, it has been attempted to analyse the stress field on the northern portion of the Hsiaokiang earthquake fault, Yunnan province. The result shows that the orientation of the principle compressive strain axis is generally north-west-west within this region, i.e. the recent compression is along this direction. |
