On July 22,2013, an earthquake of Ms 6.6 occurred at the boundary between Minxian County and Zhangxian County,Gansu Province of China. Many landslides were triggered by the earthquake and the landslides were of various types, mainly in fails, slides, and topples occurring on loess cliffs, and also including soil deep-seated coherent landslides, large-scale soil avalanches, and slopes with cracks. Most of the landslides were distributed in an elongated area of 250km2 , parallels to the Lintan- Dangchang Fault, with about 40kin in length and the largest width of 8km. Landslides occurrence shows obvious difference along the central line of the elongated area, corresponding to different charac- teristics of different segments of the seismogenic fault. The elongated landslides main distribution area and the location of the epicenter indicate that the direction of the fault rupture propagation is from southeast-east to northwest-west. Finally,two probable reasons causing the horizontal distance of about 10kin between the central line of the elongated area and the Lintan-Dangchang Fault are presented.
