A further significant failure at the site of the Alta quick clay landslide<\/h4>\n

In Friday night a further significant failure occurred at the site of the Alta Quick Clay landslide<\/a>.\u00a0 The best image that I have found of this new failure is on the nettavisen.no website<\/a>:-<\/p>\n

It appears that this is another major failure that is retrogressive from the events of Wednesday.\u00a0 This landslide is notable for the destruction of the road. Note that the landslide scar is almost completely evacuated – i.e. there is no landslide debris in sight – suggesting that this was once again a highly mobile event. The iTromso website has an image taken from a different angle<\/a>:-<\/p>\n

This image of the landslide scar shows the thick layer of marine silts and clays that is responsible for the high mobility of these landslides.<\/p>\n

I suspect that the focus now will be on securing the road, which is clearly an important transport link for people living in this area. I hope that in due course some bathymetry work might be undertaken offshore from the landslide.\u00a0 It would be extremely interesting to understand the mobility of the landslide on the seabed.<\/p>\n
