Ⅰ. DATA oF FOCAL MECHANISMS On basis of the first motion data from the Seismological Bulletins of Xinjiang stations, and the stations in China, Russia(MOS), America(NEIS), as well as World (ISC) and some other stations, we have made the P-wave first motion solutions of 107 earthquakes of M. =5 occurring in the period of 1931—1979. In addition, the focal mechanism data of 38 earthquakes in the boundary regions of Xinjiang were
