Caijiazhuang village: a cracking-sliding landslide that has killed nine people
Yesterday I highlighted recently published research into the diurnal cycle and its impacts on cracking-sliding landslides on the Loess Plateau in China. Ironically, the same day an example of such a landslide occurred, on this occasion at Caijiazhuang village in Lishi District of Lyuliang City, in Shanxi Province. Xinhua has an unusually brief report on the landslide, which notes that:
“Nine people have died in a landslide in north China’s Shanxi Province, local authorities said Monday. The landslide happened at around 4:57 a.m. Monday in Caijiazhuang village in Lishi District of Lyuliang City, the local publicity department said.”
The Li et al. (2018) research that I featured yesterday noted that these landslides occur preferentially between 10 pm and 5 am, so this landslide fits the pattern.
The Straits Times has a couple of images of the landslide:-
On the face of it this appears to meet the description of a cracking-sliding landslide, and the material appears to be loess or something similar. This image shows the landslide from a different perspective:-
The presence of the chimneys suggests that this might have been a brick pit, which in turn might imply that undercutting of the slope might have been a factor in this instability, perhaps. There are certainly signs of instability in the adjacent slopes, though perhaps not on the scale of this landslide. Li et al. (2018) found that a very high proportion of these landslides were associated with slope disturbance of some type.
