Good practices in PSHA: declustering, b-value estimation, foreshocks and aftershocks inclusion; a case study in Italy

Geophysical Journal International, 2020
The classical procedure of the probabilistic seismic hazard analysis (PSHA) requires a Poissonian distribution of earthquakes. Seismic catalogues follow a Poisson distribution just after the application of a declustering algorithm that leaves only one ...

A new approach to structural seismic responses in Mataram City: Based on the Probabilistic Seismic Hazard Analysis (PSHA) results obtained after Lombok earthquakes 2018

Scientia Iranica. International Journal of Science and Technology, 2022
. In the last few years, several major earthquakes in Indonesia have provided enough reasons for updating the existing building seismic resistance code. SNI 1726-2019 is the latest Indonesia seismic code.

PSHA: is it science?

Engineering Geology, 2002
Abstract Probabilistic seismic hazard analysis (PSHA) is beginning to be seen as unreliable. The problem with PSHA is that its data are inadequate and its logic is defective. Much more reliable, and more scientific, are deterministic procedures, especially when coupled with engineering judgment.

PSHA for the Dominican Republic

2023
The Dominican Republic, situated on eastern Hispaniola Island in the Caribbean, is subject to moderate to high seismic hazard mostly controlled by oblique convergence at the Caribbean/North American plate boundary. Offshore of the island, the North Hispaniola Trench (NHT) and Los Muertos Trough (LMT) subduction-like structures accommodate shortening ...

Earthquake Recurrence Model for the Colombia–Ecuador Subduction Zone Constrained from Seismic and Geodetic Data, Implication for PSHA

, 2021
Probabilistic seismic hazard assessment relies on long-term earthquake forecasts and ground-motion models. Our aim is to improve earthquake forecasts by including information derived from geodetic measurements, with an application to the Colombia ...

PSHA: Does It Deal with What It Is or What We Want It to Be?

Seismological Research Letters
In a recent opinion piece Albarello and Paolucci (2023; hereafter, AP23) provide their view as members of the past Seismic Group of the Commissione Grandi Rischi (CGR-SRS) in Italy, which represents the main scientific consultant for Italian Civil ...
