The analysis of the geologic tectonic background and structural units division of Longmenshan fault belt where the Wenchuan violent earthquake happened in May 2008 replies the questions about tectonic earthquakes, combined with sallow and deep structural characters of Longmenshan fault belt. It is indicated that Wenchuan violent earthquake belongs to tectonic earthquake resulted from intracontinental subduction (C-subduction), probably being the type of double major shocks plus aftershocks. Hence, it has high magnitude and intensive destruction. By comparison of the geologic conditions causing the earthquake of Longmenshan fault belt with Chengdu Plain, it is believed that a big earthquake could not take place in Chendu Plain for it locates within the stable ancient Yangtze Plate.oft-com:office:office" />
