%X 基于课题调查研究，解析历史地震记载和小南海地震遗址的现存形迹，梳理前人的认识，推算重力崩塌的势能及其相当的地震震级，探讨几种可能的地震地质灾害成因，同时也提出其他可能的诱发因素，认为小南海地震地质灾害可能是多次构造地震叠加的结果，也可能是纯粹的山体自然坍塌形成的塌陷型地震，而彻底揭开小南海地震地质灾害谜团还需人类科研实践的进一步发展，也需要更广泛学科的共同探讨。<br>Different discussions on the causes of the 1856 Xiaonanhai, Chongqing earthquake disaster are available, and different understandings of the earthquake's origin, magnitude, and epicentral intensity exist. This work analyzed historical earthquake records and the extant traces of the Xiaonanhai earthquake site in reference to previous investigations and studies. It also calculated the magnitudes of earthquakes in the Xiaonanhai area in accordance with the calculated gravitational collapse potential of several large landslides. The earthquake disaster in Xiaonanhai area may have resulted from the superposition of multiple tectonic earthquakes because four earthquakes with M ≥ 5 were located near the Qianjiang Fault Zone. Satellite images revealed the active tectonic features of the fault zone. In addition, numerous earthquakes were distributed near the fault zone. Several possible causes of seismogeological disasters were discussed, and other potential predisposing factors were presented. The Xiaonanhai earthquake may have resulted from the superposition of multiple tectonic earthquakes or from a pure mountain collapse, but other causes cannot be completely ruled out. The further development of scientific practice is needed to uncover and further discuss the mystery of the geological disaster of the Xiaonanhai earthquake
