EARTHQUAKE DISLOCATION GEOMORPHY
Fen Xianyue(Seismological Bureau of Xinjiang Vygur Autonomous Region, Urumqi)
The dislocation, generated by large earthquake, may cause the surface feature changed from its original state. This new geomorphologic landscape formed after the dislocation is called earthquake dislocation geomorphy,which can be divided into four types in detail;earthquake fault scarp, earthquake dislocation-flexural scarp, earthquake offset drainage system and earthquake offset platform. We also found colluvial wedge on the reversed fault when studying the correlative accumulation of earthquake dislocation, but the developing model of colluvial wedge is quite different from that of the one generated on normal fault scarp.
