Short summary
An important argument for the conclusion is the recognition of a regional compressive tectonic stress field in this area, which cannot lead to the formation of a fault graben, which needs a tensional tectonic stress field. Moreover, numerous unique geological features, sliding marks, and other relics of the ancient slide have been discovered in the field. A centrifuge model test shows that a deformation and failure process of "creep–crack–cut" and a type of "successive rotational rock slide" have occurred.
