Taken by a landslide

13. mars 2009 gikk tok et større kvikkleireras ved Namsos. Ingen ble drept, men flere hus ble ødelagt. Dette står fremdeles litt skjevt.


The landslide was caused by "quick clay", a marine clay that has lost most of its salt content, and when saturated with water it may suddenly liquefy. There have been a number of landslides in the district caused by quick clay, also with causualties. The worst in modern times was Verdal in 1893. 80 farms disappeared and 115 people were killed. 3 square km farmland disappeared, some places the ground was more than 50 m lower after the landslide, and the clay rushed with a speed that probably reached 60 km/h.


The picture is from a slide of a size that happens every few years. No one was killed, but approx 10 houses were lost and 7 people had to be rescued by helicopter. This page shows how the news were presented by the Norwegian Broadcasting NRK: The last landslide with fatalities in this district happened in Rissa in 1978, but some hundred km further north people were killed in a different kind of landslides in 1988 and 1996.
