Methods for evaluating the significance and importance of differences amongst probabilistic seismic hazard results for engineering and risk analyses: a review and insights Bull. Earthquake Eng. (IF 4.6) Pub Date : 2024-03-30 John Douglas, Helen Crowley, Vitor Silva, Warner Marzocchi, Laurentiu Danciu, Rui Pinho
When new seismic hazard estimates are published it is natural to compare them to existing results for the same location. This type of comparison routinely indicates differences amongst hazard estimates obtained with the various models. The question that then arises is whether these differences are scientifically significant, given the large epistemic uncertainties inherent in all seismic hazard estimates
