Neonor 2

Published: February 23rd 2015 | Last change: February 8th 2016
This was the area hit by an earthquake in 1819. One of the outcomes was several landslides. The picture shows the edge of a landslide beside the Storsand farm at Utskarpen Bay in Ranafjord.
In the Nordland County area of Norway, is an area where there is a lot of movement in the earth’s crust.

This is one of the areas that was mapped during the first NEONOR-project (Neotectonics in Norway, 1997-2000) with the help of earthquake records and GPS measurements. In collaboration with the Norwegian Mapping Authority, NORSAR, the University of Bergen, NORUT and the University of Luleå, NGU will examine the current crustal deformation in a large area along the Nordland coast. The NEONOR 2 project will determine if these movements are caused by erosion and unloading during past ice ages.

NORSAR and the UiB have set up several seismic stations, while the state mapping authority will monitor movements in bedrock from its network of permanent GPS stations. Satellite radar images will be analyzed by NGU and NORUT in order to measure small movements in the bedrock. The University of Luleå will measure crustal stress within boreholes.  NGU will develop various models in order to determine the mechanisms behind the ongoing deformations.  In addition to the crustal stress data, heat flow and crustal deformation will be included in the calculations. Movement within the bedrock might cause reservoirs to crack, which could result and in gas and oil leaks. Oil companies must consider such scenarios during exploration in this area.
