The Zuta Village landslide: another example of a high mobility slide<\/h4>\n

I have written on several occasions of late about high mobility landslides, both in the context of the Regent landslide in Sierra Leone<\/a> and the Oso landslide in Washington State<\/a>.\u00a0 As an aside full mapping is now available of the track<\/a> of the extraordinary Regent landslide<\/a> – as expected this was a channelised flow all the way to the coast.\u00a0 Another very interesting example popped up in my Google Alerts yesterday, although the landslide occurred in early July.\u00a0 This example is the Zuta Village landslide<\/a>, which occurred during heavy rainfall in Hunan Province, central China, on 1st July.\u00a0 The landslide killed nine people and injured a further 19<\/a>.\u00a0 This image, from Xinhua<\/a>, provides an overview of the landslide:-<\/p>\n

This view provides a better indication of the source area of the landslide:-<\/p>\n

This appears to be a comparatively shallow translational failure in deeply weathered soil that has transitioned into a high mobility flow, presumably through some sort of liquefaction process.\u00a0 There are marked similarities with the Regent landslide in terms of material and mobility, although in this case the mass has not been able to channelise.\u00a0 The nature of the sliding surface in the source area is also unclear, but the image below suggests the involvement of at least some intact rock:-<\/p>\n

As an aside, this set of images also illustrates the ways in which humans can contribute to increased landslide risk.\u00a0 The source area of the landslide is traversed by a road cut into the slope and appears to have been partially deforested.\u00a0 And, separately, a house has been built into the slope, as this detail from the above images shows:-<\/p>\n

To build this house forest has been stripped and slopes cut, increasing the likelihood of failure.\u00a0 Even worse the building is at the exit of a gully draining a substantial, steep catchment.\u00a0 The first image shows that this catchment has been substantially deforested.\u00a0 This must be subject to debris flow risks.\u00a0 On first inspection this is a further landslide accident in the making.<\/p>\n","protected":false},"excerpt":{"rendered":"
