- Abstract
The Wenchuan earthquake and the Hongdong earthquake are earthquakes of magnitude 8.0 occurring in the north and south of China: the Hongdong earthquake occurred in the Linfen Basin on the Loess Plateau. The thick Quaternary basin produced surface rupture, sand liquefaction and soft under earthquake action. Many earthquakes such as soil subsidence and landslides have a small population distribution in the earthquake-stricken area. Therefore, the macro-seismic epicenter is located in the center of a densely populated basin, which is inconsistent with the typical epicenter distribution area. The Wenchuan earthquake occurred in the southwest mountainous area where the geological structure is active. A large number of geological disasters such as collapse, landslides, and dammed lakes have been induced. Due to the densely populated areas in the epicenter, the personnel are dense, resulting in a large number of personnel and property losses. A series of typical seismic geological disaster distribution areas and macroscopic earthquake areas have Very good consistency distribution.
