Mapping of the distribution and properties of marine clay is important in Norway due to numerous landslides in sensitive clay. The degree of leaching of salt in marine clay may be reflected by its electrical resistivity. However, the degree of sensit

In recent years, the focus on feasibility studies for tunnels has increased in Norway. Traditionally, the refraction seismic method and the very low-frequency electromagnetic method (VLF-EM) have been used. The Geological Survey of Norway introduced

Thick, marine clay deposits in valleys along the Norwegian coast are occasionally subjected to large landslides involving quick clay. Detailed mapping of the extent of quick clay is of great interest for planning and protection purposes, as the posit

Knowledge of occurrence and extent of quick clay is vital regional for hazard zonation and in detail for infrastructure projects. Quick clay poses a serious geohazard in Scandinavia and Canada (amongst others) as it practically liquefies at failure a

There was a quick-clay landslide in Byneset, Mid Norway on 1st January 2012. The landslide area is surrounded mostly by agricultural lands. The geology in the area consists of old ocean floor with outcropped bedrock at several places. Prehistorically

Results from site investigations, 2D resistivity, refraction seismic and VLF on a section of tunnel near Trondheim, show that 2D resistivity data are most valuable for interpreting geological structures in the sub-surface. VLF only identifies zones a

During the last 10 years, several Norwegian projects have explored the possibilities of using 2D resistivity measurements for quick-clay mapping in combination with traditional geotechnical methods. Experience has shown that an effective first-order
