Eastchurch – a coastal landslide in Kent, SE England<\/h4>\n

Over the weekend the newspapers in the UK have been reporting two coastal landslides that occurred at Eastchurch on the Isle of Sheppey in Kent.\u00a0 These two landslides, which occurred at the same site, have damaged a house.\u00a0 The first failure occurred at 10 pm on Friday 29 May 2020:-<\/p>\n

This is quite an interesting landslide, with an unusual linear geometry in the rear scarp, similar to a wedge.\u00a0 The Isle of Sheppey consists mainly of London Clay<\/a>, which is well known for the presence of fissures and joints<\/a>.<\/p>\n

Over the weekend the situation deteriorated substantially, and on Sunday 1 June 2020 a further substantial landslide occurred, causing damage to the house closest to the cliff:-<\/p>\n

The site of the landslide is 51.418, 0.873, as shown below.\u00a0 I have marked the rear scarp of the second landslide at Eastchurch:-<\/p>\n

As the Google Earth image shows, this section of coast is highly landslide-prone.\u00a0 Indeed, the Isle of Sheppey is well-known for its coastal landslides in the London Clay<\/a>.\u00a0\u00a0\u00a0 However, there are two aspects of this event that are quite surprising to me.\u00a0 The first is that the slide has occurred in the middle of a spell of exceptionally dry weather – indeed this has been the sunniest Spring on record<\/a> and parts of the UK have recorded their driest Spring on record too.\u00a0 Perhaps this slide was associated with dessication rather than high pore water pressures?\u00a0 But second, the images after the landslide yesterday seem to show a great deal of water in the rear scarp of the landslide:-<\/p>\n

It is not clear to me as to the source of this water, although it could be that the failure has ruptured a pipe?<\/p>\n

It goes without saying that this is a devastating landslide for the occupants of the house.\u00a0 In general, UK house insurance does not cover damage caused by landslides or by coastal erosion.<\/p>\n

.<\/p>\n

On reflection 1: too good to be true?<\/h4>\n

Various news outlets report a miracle recovery of a newborn baby buried in a landslide in Northern India<\/a>.\u00a0 The baby appears to be thriving in hospital, but the idea that a baby could survive burial in a landslide without any protection is surprising.<\/p>\n

On reflection 2: 50 years after Yungay<\/h4>\n

Yesterday was the 50th anniversary of the devastating landslide at Yungay and Ranrahirca in Peru<\/a>, caused by a seismically triggered landslide from Mount Huasaran.<\/p>\n","protected":false},"excerpt":{"rendered":"
