The remarkable landslide in an olive grove near to Hatay, triggered by the Turkey-Syria earthquakes<\/h4>\n

Yesterday marked one month since the 6 February 2023 Turkey-Syria earthquakes<\/a>, which have had such a devastating impact across a wide area of both countries.\u00a0 Investigations of the coseismic landslides continue – I recommend the Twitter account of the SLATE-landSLide Assessment TEam<\/a> (@SLATE_landslide), a group of Turkish landslide specialists who are providing updates on their work investigating the major failures.<\/p>\n

One landslide that has attracted some interest is the large failure in an olive grove near to Tepehan, which some people have termed the Hatay landslide.\u00a0 The location of the failure is [36.161, 36.222].\u00a0 My friends at Planet<\/a> have very kindly captured before and after satellite imagery of the failure using the high resolution SkySat instrument.\u00a0 This is the site before the landslide:-<\/p>\n

Whilst this is the same site after the earthquake:-<\/p>\n

In the media there has been some confused reporting about this landslide, with some mistaking the landform for the fault rupture.\u00a0 This is a block slide type of failure, probably on a weak layer in a dip slope, which has allowed parts of the olive grove to remain intact despite large displacements.\u00a0 This block diagram from the USGS explains the concept well:-<\/p>\n

Robin Lacassin has a good tweet that highlights the main features of the landslide close to Hatay:-<\/p>\n

There is quite a nice video on Youtube showing the aftermath of the landslide<\/a>:-<\/p>\n
