Session 2.1 GNGTS 2023 peak. The set of product PDFs constitutes the earthquake chronology of the fault. The algorithm is also stabilized to clear the influence of noisy peak detections and, most-importantly, to detect instances in which the product PDFs might represent the occurrence of more than one earthquake (i.e., when events in a site cannot be distinguished into separate PDFs due to lack or insufficient age resolution). The results of the workflow are presented in simple output files that can be used to compute fault parameters for the seismic hazard. The approach has been preliminarily tested in several paleoseismic datasets including the Central Apennines (Italy), the Eastern Betics (Spain), the Wasatch Fault (US) and the Dead Sea. Such tests have yielded positive results so far, showcasing an improvement in the uncertainties of event times and providing more complete earthquake chronologies compared to the visual/manual correlations carried out previously. We also aim that the approach provides researchers with a tool to perform more objective analyses of trench datasets, especially when these are complex. Furthermore, the approach can potentially help to better assess researchers into fault parameters such as recurrence times and recurrence models that describe the fault behavior.
