翠花岩雪崩位于中国西安以南30公里处，是由一次古地震引发的。区内以悬崖、石海和堰塞湖（水秋池）为主，总面积5 × 105 m2，容积1.8 × 107 m3。现场调查、历史记录、测年方法和典型地震剖面表明，它的发生可能与公元前780年的地震有关，最有可能引发滑坡。研究结果还表明，秦岭山体抬升形成的高陡边坡和岩石裂隙的切割作用是导致崩塌的主要原因;高陡边坡和多个优势结构面对滑坡的失稳起着重要的控制作用。根据岩石崩落破坏过程的特征，将其划分为四个阶段：初始阶段、启动阶段、加速阶段和积累阶段。
The Cuihua Rock Avalanche, 30 km south of Xi'an, China, is located within a marvelous geological landscape and was triggered by an ancient paleo-earthquake. The area is mainly characterized by cliffs, stone seas and a dammed lake (Shuiqiu Pool), with a total area of 5 × 105m2and a volume of 1.8 × 107m3. Field investigations, historical records, dating methods and typical seismic profiles indicated that its occurrence could be correlated with an earthquake in 780 BC that most likely triggered the landslide. The results also showed that a) the formation of the rock avalanche was associated with high-steep slope created by lifting of Qinling Mountain and cutting of rock fractures, and b) the high-steep slope and several preferred structural planes play an important role in controlling the slope instability. Based on conjectures, the failure process of the rock avalanche can be divided into four stages: the preliminary stage, the starting-up stage, the accelerating stage, and the accumulating stage.
