摘　　要：１９３２年昌马地震构造力学特征探讨郭万武，张范民，邢成起，温增平（国家地震局兰州地震研究所，兰州）ＤＩＳＣＵＳＳＩＯＮＯＮＴＨＥＴＥＣＴＯＮＯＭＥＣＨＡＮＩＣＦＥＡＴＵＲＥＳＯＦ１９３２ＣＨＡＮＧＭＡＥＡＲＴＨＱＵＡＫＥＭｓ７．６￥ＧｕｏＷａｎｗｕ；...On the basis of the distribution of small shocks (2. 0≤Ms<5. 0)around Changma area measured by instrument during recent thirty years,and combining them with deep tectonics as well as the regional tectonic stress, we have discussed the tectonomechanic features of 1932 Changma earthquake Ms7. 6. There may be three faults intersected in the area,in which the NW trending fault is obvious in surf see and the NE and near EW trending faults are two blind deep rupture. We propose the Changma earthquake could be caused by the activity of NWW trending fault in the upper layer under the left-lateral slip along the near EW directional fault in the lower layer.
