In this paper, extensive research and discussion for Pakistan earthquake with MS7. 7 on September, 2013 carried out according to basic data including the activity process, tectonic environ-ment, seismic activity background and causes of earthquakes. The results showed: Pakistan earth-quake was caused by inheritance motion of left rotary of the Chaman fault under background of Hin-dukush anti-clockwise twisting movement, which was formed by Eastern Hemisphere overall clock-wise rotation, and deep-seated reason was earthquake energy accumulation and controlled by Hin-dukush seismic cone, perhaps deep fluid involvement, fluid upwelling ( gas or liquid) and surface fault dislocation were happened together. Pakistan had special tectonic conditions and seismic back-ground, perhaps caused earthquake prediction more difficult. In this paper, relationship between the seismic activity and the seismic tectonic in the earthquake affected area in cones.%针对2013年9月巴基斯坦7.7级地震活动过程的基本资料，就其构造环境、地震活动背景，以及地震的成因，进行了广泛的研究和讨论。研究结果表明，巴基斯坦7.7级地震是在东半球总体呈顺时针旋转的背景下形成兴都库什逆时针旋扭运动，从而致使Chaman断裂左行继承性活动而造成的，其深层次的原因是兴都库什地震柱活动的能量累积与控制，或有深部流体的参与，而致流体(气体或液体)的上涌与地表断层的错动并发。
