WebMay 15, 2024 · While probabilistic methods are mainly used to characterise seismic hazards, there is the potential to further reduce uncertainty in the case that a known fault is activated (i.e., deterministic hazard). In such a case, we can isolate seismicity related only to this particular fault (e.g., using cross-correlation) in order to obtain associated ... WebNov 1, 1995 · The probability is :laimed to be a measure for uncertainty. The general procedure is as follows: Step 1: Same as for a deterministic evaluation.
