卡兹克阿尔特断裂是青藏高原西北边缘的一条倾滑型性质的强震发生带。全新世时期至少有过3次强震活动幕,距今最近一次古地震活动幕的时间大约在600年前,每个强震活动幕持续时间为10年左右。预测今后百年内发生7级以上强震的危险性很小。本文首次提出断层挠曲崖和推覆楔是倾滑型地震断层所特有的,可作为倾滑型地震的鉴别标志。 The Catskick Alt fault is a slippery-type strong earthquake occurrence zone on the northwestern margin of the Qinghai-Tibet Plateau. During the Holocene, there have been at least 3 strong seismic activity curtains. The time of the last ancient seismic activity curtain was about 600 years ago, and the duration of each strong earthquake activity curtain was about 10 years. It is predicted that there will be little danger of strong earthquakes of magnitude 7 or higher in the next 100 years. This paper presents for the first time that the faulty flexure cliffs and the nappe wedge are peculiar to the dip-slip seismic fault and can be used as the identification mark of the dip-slip type earthquake.
