Guanxian faults. The Wenchuan earthquake is a thrust with strike-slip type, and thre surface ruptures are located on the Beichuan-Yingxiu fault zone and Pengxian-Guanxian fault zone. The surface rupture on the Beichuan-Yingxiu fault shows the thrust and dextral slip charac-teristic. The maximum vertical displacement of the surface rupture is about 10.3 m and the maxi-mum right-lateral displacement is about 5.85m. Though the vertical displacements and the hori-zontal displacements in the different segments have certain differences, as a whole, the ratio of the vertical displacement and the horizontal dis-placement is close to 1:1. The surface rupture on the Pengxian-Guanxian fault shows thrust and dextral characteristic. The rates of vertical dis-placements and the horizontal displacements ones on the most other segments are between 1:3 and 1:2. So the Beichuan- Yingxiu fault is a dextral-slip and thrust fault and the average ver-tical displacement is equal to the average hori-zontal displacement, while the Pengxian- Guan xian fault is thrust fault with a little dextral-slip component. The total intensity area above ¢ö de-gree of the Wenchuan earthquake is about 333000 km2. The high earthquake intensity line stretches to N40-50¡ãE along Longmen Shan tectonic belt. The rate of the long axis and the minor is betw- een 8:1 and 10:1. Three ¢û intensity regions are isolated in distribution. It presents a multipoint instantaneous characteristic of the rupture.
