The diverse geology and topography under the town is likely to contribute to localized differences in site effects and spatially variable earthquake strong-motions, indicating significant relative differences in seismic risk to its inhabitants. Previous earthquake hazard estimates of this region have relied on a single ground motion model and incorporated uncertainties in a limited way, but pointing out several ways to improve the hazard estimates. In this paper, a probabilistic seismic hazard analysis (PSHA) of the area of Húsavík in terms of peak ground acceleration (PGA) and spectral accelerations (SA) is presented using the Monte-Carlo (MC-PSHA) and Cornell-McGuire (CM-PSHA) methods, respectively. We considered different ground-motion models and selected the best model based on data-driven approaches. Both aleatory and epistemic uncertainties are taken into account. Moreover, the disaggregation of the seismic hazard is carried out to identify hazard-dominating events. The presented results shed further light on the earthquake hazard of Húsavík with implications for the associated seismic risk.
