Figure 13

The survey of geomorphological changes of the eastern slope of the Yanqianshan Iron Mine (October 2016). (a) 3D view from Google Earth (17/10/2016). (b) The location of the mining area, which is observed through the same viewing angle as that of the Google Earth image (October 2016). (c) Counterscarps showing rock toppling failures on the phyllite slope. (d) Scarps away from the small landslide. (e, f) Tension cracks along the eastern boundary of the large landslide.
