Vestfold, Norway<\/h5>\n

Yesterday afternoon a really interesting landslide occurred at Vestfold, to the south of Oslo in Norway.\u00a0 This is the site of an elevated two lane in each direction highway – the major road that runs southwest from the capital.\u00a0 The landslide, which occurred on the edge of a small river, destabilised one of the pillars supporting the motorway, causing massive deformation of the road deck.\u00a0 Fortunately no-one was hurt.\u00a0 The event is described nicely in this report in English<\/a>.\u00a0 These two images, from this forum<\/a>, show the landslide and the deformation of the bridge deck:<\/p>\n

This looks like a classic Norwegian quick clay landslide<\/a> to me, but that is just speculation.\u00a0 Such landslides are often triggered by a comparatively minor disturbance that then triggers massive instability – the Rissa landslide<\/a> being the most famous example.\u00a0 And interestingly, the images suggest that there was work going on under the bridge, because right in the middle of the landslide there is a bulldozer:<\/p>\n

Unconfirmed posts on the forum suggest that this machine was doing some work reprofiling the field without the knowledge of the highways agency.\u00a0 Unfortunately this is going to take a long time to repair.<\/p>\n","protected":false},"excerpt":{"rendered":"
