Åknes is known as the most hazardous rockslide area in Norway at present, and is among the most investigated rockslides in the world, representing an exceptional natural laboratory. This study focuses on structural geology on five zones to interpret and understand the geometry of the rockslide area. The interpretations are further used to build a geological model of the site.
The Mjølnir impact crater was discovered in seismic reflection data in the 1990's and the detailed structure is well established. The submarine crater, situated in the southwestern Barents Sea, is believed to have a crater diameter of about 40 km, and a shallow relief (About 50 m). The crater is buried under a layer of sediments. Stratigraphic relationships (drill core 7329/03-U01) indicate a Cretaceous formation age around 140 Ma.

The previously defined Sandøla and østre Skorovas Cu, Pb and Zn provinces are united and enhanced by new high-metal samples in the Fremstfjellet and Neså- piggen districts, which also define a new Mo province. The Østre Skorovas province is extended up to Tunnsjøen. Mo, Cu and Zn mineralisation has been found in the Fremstfjellet area; these elements show a good correlation between high-metal concentration in stream sediment samples and the principal underlying bedrock type.
Movement of the Earth's plates through geological time can be described in therms of a series of rotations on the sphere (Earth). If we can determine what these rotations have been, we can rotate ancient geological features on the Earth's plates back to their former positions to produce paleogeographic maps. We present an open source computer program that performs such rotations on the sphere.
The international nuclear emergency exercise Barents Rescue took place in the vicinity of Boden in Northern Sweden between the 12th and 20th of September 2001. The Gamma Search Cell part of the exercise was designed to test the abilities of car-borne and air-borne measuring systems to quickly locate and characterise radioactive sources hidden in the countryside.

Catastrophic failure of large rock slopes in Norway has several times per century led to rock avalanches or large rock falls, which impacted into settlements directly, but also caused either a displacement wave when impacting a water body or damming of narrow valleys with often fatal consequences. Such events will also occur in the future.
Young Trondhjemites, the conference for young researchers working with geosciences and engineering in Trondheim, has been arranged in 2018 for the third time.

Geokjemiske data fra NGU's blyprosjekt korreleres med prevalense data for multiple sclerose. Denne forberedende undersøkelsen synes å indikere at: -kompleks geologi gjør det nødvendig å inndele de geokjemiske data i små homogene underområder -de medisinske data må inndeles i mindre enheter enn herreder -metallinnhold i de ulike geologiske formasjoner bør bedømmes -det kan være ønskelig med supplerende prøvetaking.
