000019066 520__ $$2eng$$aThe Tjornes Fracture Zone (TFZ) of North Iceland is one of the most active seismic zones in northwestern Europe. While the earthquake of 1910 with M=7.2 is the largest observed earthquake in TFZ, due to the uncertainty inherent in the Icelandic earthquake catalog at present, in addition to the limitations of the written historical annals, there does not at present exist a consensus on the maximum potential of seismic sources in the region. However, for earthquake hazard studies the maximum earthquake potential of the TFZ seismic sources, needs to be evaluated either by deterministic or probabilistic approaches. In this study we carry out the analyses to estimate the maximum magnitudes, starting by revising the TFZ earthquake catalog in order to obtain a more consistently homogeneous, accurate and complete catalog. Moreover, earthquake events attributed as dependent, such as aftershocks, have been removed. We found that for active seismic regions such as the TFZ where the main faults have been identified, deterministic approaches are a better choice. We also found that results on the basis of probabilistic approaches appear to be disproportionally influenced by the estimates of the maximum observed magnitude earthquake.
