In this paper, the distribution pattern of the earthquake surface rupture zone around Hanwang town is discussed, focusing on the causes for the aggravation of seismic damage. The paper introduces two left-step en echelon surface rupture zones, which are oft-com:office:smarttags" />1.5 km apart, located at the north and south of Hanwang town. The one on the north of Hanwang town has a vertical displacement of 1.4m and horizontal dextral displacement 0.44 m, respectively. The other on the south of Hanwang town has a vertical displacement of 3.0～0.2 m, descending from west to east.  The seismic damage of Wenchuan earthquake around Hanwang town shows that the stepover of the surface rupture zone is also the special structural part subject to aggravated damage in earthquake.oft-com:office:office" />
