摘要: 1986年作者在特克斯-昭苏盆地首次发现长70公里、最大垂直和水平位移均达8米的地震断裂带和地震形变现象,并认为是1716年地震时形成的。地震断裂带的展布和运动方式,与科博河-昭管处断裂相一致。特克斯断裂带是一条复杂的断裂带,它由多条断裂组成。1716年地震表明该断裂带具有新的活动性。

Abstract: A seismic fracture zone was found in 1986, when authors explored Tekes-Zhaosu basin. This fracture zone extends to 70 km long and its maximum vertical and hori-zantal displacements are both 8 and meters the other seismic deformation phenomena were also seen. We stadied these phenomena and drew an isoseismac map. The age, epicenter and magnitude of the earthquake have been discussed too. This fracture zoneis cor-sidered as the result of the earthquake in 1716.The trend and motion of this earthquake fault is consistent with the Kebo river-Zhaoguanchu fractures. It is shown that this fracture zone is the result of a left-lateral overthrust.Tekes fracture zone is a complex zone, consisted of several fractures. The earthquake in 1716 showed that the Tekes fracture was a recent active fault.
