First, my thanks to Ellen Hardy for pointing this one out.<\/em><\/p>\n

Actually it is not really a landslide, but it is an example of the “strange” ways that the ground can behave.\u00a0 The Southern USA has recently been affected by heavy rainfall.\u00a0 In Leslie, Georgia, a homeowner was somewhat surprised when his empty swimming pool popped out of the ground.\u00a0 WALB News 10 has the full story<\/a> with a selection of photographs, although the best one is on the News 8 website<\/a>, which also has a video:<\/p>\n

An empty swimming pool is of course in effect a boat.\u00a0 When the groundwater level becomes sufficiently high it will start to float upwards unless it is properly anchored down.\u00a0 In this case it clearly was not.<\/p>\n

This does illustrate some of the problems of interpreting the movement of landslides – sometimes strange things appear to happen through simple physics.\u00a0 Landslide movement is usually controlled by buoyancy forces, which technically we term effective stress, operating in a very similar manner.<\/p>\n","protected":false},"excerpt":{"rendered":"
