NKS-R ADdGROUND

15th December 2015, Copenhagen, Denmark

Background

Significant hazard to a site in Fennoscandia is generated from mid-magnitude seismic event with epicenter localized in the proximity. Earthquake source modeling can be used to understand vibrations in areas close to the earthquake epicenters; but source modeling in stable continental region has limited research background. Different modeling techniques were used for modeling fault stresses/rupture in glaciation scenarios (Lund & Schmidt, 2011) and earthquakes Fälth et al (2014). Uncertainty in such complex models is significant. Measured data from earthquakes and/or explosions can be used to calibrate models.

Modelling techniques were discussed and exploratory modelling work was presented.
