L. and Costa, A. C., "Ground motion scenarios consistent with probabilistic seismic hazard disaggregation analysis. Application to Mainland Portugal” [Elektronische Daten] [João Fonseca, Susana Vilanova] Disaggregation of the seismic hazard has become a popular technique to convey information on the main sources contributing to the hazard at a particular site. Recently published work adopts geographic disaggregation analysis of seismic hazard as a tool to identify dominant rupture scenarios for municipalities in Mainland Portugal. The authors conclude that the seismic hazard in South and Central Portugal is dominated by the seismicity that takes place offshore, around 70km WSW of Cape S. Vicente, both for the return periods of 475years and 975years. Whilst recognizing the merits of the approach taken and the utility of the tools developed, we take issue with this last conclusion. We consider that the proposed disaggregation returns a picture of the biases in the hazard analysis, more than any real feature of the distribution of relevant seismogenic sources.
