Abstract
Land-use planning in regard of earthquake-triggered land- slides is usually implemented by means of the production of hazard maps. The well-known Newmark rigid block method- ology is the most frequent used approach for this purpose. In this method, slope stability is evaluated by the estimation of the Newmark displacement, which is used to set differ- ent categories of hazard. This methodology presents limita- tions due to the difficulty of incorporating the variability of the used variables. For that reason, the logic-tree approach has been used in order to incorporate the epistemic uncer- tainties and compute probabilistic seismic-landslide hazard maps. However, the used weights in the logic-tree are usually set for each branch based on an expert judgement or sub- jective criteria. This article provide data obtained from the use of logic-tree methodology; this dataset is useful for de- riving the unbiased weights to use in such methodology and in moderate-to-low magnitude scenarios. The data presented here are related to the article entitled “Obtaining suitable logic-tree weights for probabilistic earthquake-induced land- slide hazard analyses”File | Dimensione | Formato | |
