In this work we evaluate the use of Markov-modulated Poisson process (MMPP) framework in the computation of the Peak Ground Acceleration (PGA) for a 475-year return period through a classical Time-Dependent Probabilistic Seismic Hazard Assessment (TD-PSHA) approach. The catalogue of Southern Spain spanning from 1970 to 2023 has been selected using several tectonic zones from the nation seismic zonation as masks for the extraction, then homogenized and declustered.

Abstract
In this work we evaluate the use of Markov-modulated Poisson process (MMPP) framework in the computation of the Peak Ground Acceleration (PGA) for a 475-year return period through a classical Time-Dependent Probabilistic Seismic Hazard Assessment (TD-PSHA) approach. The catalogue of Southern Spain spanning from 1970 to 2023 has been selected using several tectonic zones from the nation seismic zonation as masks for the extraction, then homogenized and declustered.File in questo prodotto:
