NGI | Natural hazards
NGI assesses the risk of landslides, rock fall and avalanches, and helps industry, the authorities, police and land owners manage acute situations and prepare protective and other risk-reducing measures.
NGI works with natural damage resulting from avalanches, debris flows, landslides, floods and earthquakes. The Planning and Building Act stipulates requirements for the assessment of natural damage in connection with all construction activity in Norway. NGI offers advice and guidance to developers and authorities with regard to prevailing legislation.
NGI has internationally recognised expertise in assessing the risk of natural damage. We help protect life and material values. Specialist expertise within the fields of natural geography, meteorology, geology, geomorphology, geotechnics, hydrology, rock mechanics, wave dynamics, monitoring technology, information technology, mathematics and physics gives us a unique basis as advisers to industry, authorities, land owners and other parties responsible for safety.
Our experts are familiar with local conditions in the majority of landslide, rock fall and avalanche-prone areas in Norway and have access to more than 50 years of experience data. We have mapped landslide-prone quick clay zones, as well as areas in Norway vulnerable to avalanches and rock slides. NGI has its own avalanche research station on Mount Strynefjellet and an office in Stryn. In the majority of major landslide, rock fall and avalanche incidents, NGI is approached to assist local authorities and offer advice on safety.
Assignments and specialist expertise
We assess landslide, rock fall and avalanche risks and operate landslide, rock fall and avalanche warning systems for the Norwegian Public Roads Administration, the Norwegian National Rail Administration and several local authorities, among others. The Norwegian Armed Forces utilise NGI's landslide, rock fall and avalanche expertise during all NATO winter exercises in Norway. NGI has actively worked on assessing landslide risk at Åkneset in Stranda municipality. Both here and in other fjord municipalities in North Western Norway, we have carried out detailed inundation modelling of tidal waves formed by landslides.
NGI's instrumentation department can supply customised monitoring systems for natural damage scenarios. For the authorities in Thailand and in partnership with several Norwegian institutions, NGI has assessed the risk of future tidal waves and prepared strategies in connection with this.
Driving force for the development of the geosciences
NGI frequently brings together authorities and institutions with landslide, rock fall and avalanche expertise to exchange experience. Participation in national and international research projects contributes to enhancing our expertise.
NGI took charge of one of the first centres of excellence, the International Centre for Geohazards (ICG). In partnership with the University of Oslo, the Norwegian University of Science and Technology and Norsar, NGI carried out R&D on geohazards via the ICG from 2003–2012.
NGI was one of the main participants in the Geoextreme project and led the InfraRisk project that dealt with landslides, rock fall and avalanches, climate change and extreme weather events with regard to road and rail in Norway. NGI actively participates in several EU projects in the field of landslides, rock fall and avalanches and risk management and thus has close contact with international research.
