摘　　要：用P波初动对青海区域1992年来的6次哈佛大学及USGS等机构均未给出结果的5级以上地震震源机制解进行了计算。通过区域断裂构造的展布与本文计算出的震源机制解的对比,计算了青海境内2次地震的震源机制解,并与哈佛大学给出的结果进行了对比,表明计算结果较为可靠。The focal mechanism solutions of the six middle - strong earthquakes from 1992 in Qinghai region were calculated, and Harvard University and USGS had not offered those solutions. The authors compared the solutions with the fault distribution, and also compared the focal mechanism solutions of two earthquakes with the results given by Harvard University, and the results show that the solution which we had calculated is reliable.
