NORSAR is one of 5 partners in a Norwegian Centre of Excellence called the International Centre for Geohazards (ICG). The Norwegian Centres of Excellence are an initiative from the Research Council of Norway to provide funding for internationally leading research groups in Norway. The Partners of ICG are the Norwegian Geotechnical Institute (NGI, host institution), the Geological Survey of Norway (NGU), NORSAR, the University of Oslo, and the Norwegian University of Science and Technology in Trondheim.
ICG carries out research on the assessment, prevention and mitigation of geohazards and contributes to the education of researchers and specialists in these fields. NORSAR participates in ICG with expertise in geophysics, especially in seismology, seismic risk, micro-seismic monitoring, near-surface geophysics, and seismic modelling and imaging in petroleum and near-surface applications.

NORSAR is responsible of the ICG Project 3 Seismic hazard, risk and loss, which performs research on quantification of earthquake hazard, including the influence of soil amplification characteristics, seismic vulnerability of the built and populated environment, development of models and software tools for risk quantification and loss modeling at different scales. The term earthquake hazard refers to the occurrence probabilities of damaging ground motions, exclusively relating to natural phenomena and processes, while risk and loss results from combining the earthquake hazard with the vulnerability of the building stock.
NORSAR is also leading ICG Theme 1 Geophysics for Geohazards since 2005 to better include geophysics as one of the 3 ”G” at ICG, i.e., beside geotechnique and geology, all 3 expertise domains working in a cross-disciplinary manner. ICG T1 is continuously working towards a best-practice approach in using geophysics for geohazard assessment (quick clay, rock slides, submarine slides, etc), with integration of different data types by maintaining an open dialog between the different experts and working closely with the relevant ICG projects.
In addition, NORSAR researchers participate to various activities within the other ICG projects and themes, such as stability of rock slopes with micro-seismic monitoring, Offshore Geohazards, Ground-based Interferometric SAR, Earthquake sources for tsunami modelling, etc.
