古浪地震滑坡及其与断裂带的关系

THE RELATION BETWEEN THE GULANG SEISMIC LANDSLIDES AND FAULT BELTS

摘要:

本文根据航片解译和野外调查,首次介绍了古浪8级大震的地震滑坡的主要特征和分布情况,探讨了古浪地区地震滑坡与断裂带的关系,发现地震滑坡和崩塌明显受断裂构造的控制。

Abstract:

The disasters of landslides and slumps caused by earthquake have not been systematically studied since the 1927 Gulang M8 Earthquake occurred in Gansu Province. This paper, for the first time, intrduces the main features of the seismic landslides based on the interpretations of the air-photos and field investigation, and discusses the relation between the distribution of seis-mic landslides and the fault belt in the Gulang region.
The result has a certain meaning to analyzing the seismotectonic environment of the Gu-lang M8 Earthquake and forecasting the seismic landslide and land fall disasters.
