| Abstract: | Geometric pattern,distribution features and mechanics nature of surface rupture zone at Shangsi area are described.The mechanism of formation of the surface rupture zone is studied.It is proved that the Shangsi rupture zone is engendered during the Gulang earthquake,and is part of the rupture zone of the 1927 Gulang M S8 earthquake. |
| Keywords: | Gulang earthquake Gansu Tectonic stress field Surface rupture zone Shangsi |
