タイトル(英): A METHOD FOR EVALUATING UNCERTYAINTY IN SEISMIC HAZARD BASED ON A MONTE CARLO APPROACH
抄録(英): We developed a logic tree model for evaluating uncertainty in seismic hazard for the Kanto district. The uncertainties in a seismic source model with temporal dependence of large earthquake occurrence and an attenuation model were represented by either discrete branches or continuous probability distributions associated with each node in the logic tree. The nodes for the seismic source model were magnitude distribution, maximum magnitude, mean and variability of recurrence interval, seismic source location and geometry, and division of seismic source zones. Uncertainty in the hazard was evaluated using a Monte Carlo approach and displayed by 5-, 16-, 50-, 84- and 95-percentile hazard curves.
