PSHA Validated by Quasi Observational Means [PDF]
Seismological Research Letters, 2012 It might seem odd to be writing about confirmation of the validity of probabilistic seismic hazard assessment (PSHA) in 2011, given that the method has been successfully applied in countless studies worldwide over the last 40 years. However, the fact that papers still occasionally find their way into print attacking the method as mathematically invalid

Why is Probabilistic Seismic Hazard Analysis (PSHA) still used? [PDF]
Physics of the Earth and Planetary Interiors, 2017 Abstract Even though it has never been validated by objective testing, Probabilistic Seismic Hazard Analysis (PSHA) has been widely used for almost 50 years by governments and industry in applications with lives and property hanging in the balance, such as deciding safety criteria for nuclear power plants, making official national hazard maps ...

Philosophical aspects of probabilistic seismic hazard analysis (PSHA): a critical review [PDF]
Natural Hazards, 2023 The goal of this paper is to review and critically discuss the philosophical aspects of probabilistic seismic hazard analysis (PSHA). Given that estimates of seismic hazard are typically riddled with uncertainty, diferent epistemic values (related to the

PSHA for the Dominican Republic
2023The 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 ...

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.

General Concepts and PSHA Background
2017The first step in building the PSHA model is the collection of geological, geophysical, geotechnical and seismological data from published and unpublished documents, theses, and field investigations. These data are integrated to develop a coherent interpretation of a seismotectonic framework for the study region.

STATUS OF THE PSHA IN KOREA FOR NUCLEAR POWER PLANT SITES [PDF]
Nuclear Engineering and Technology, 2009 This paper introduces the status of and issues related to the PSHA (Probabilistic Seismic Hazard Analysis) of Korean Nuclear Power Plant sites. PSHA was first introduced to the nuclear industry in the mid-1980s. The Korean PSHA is based on Cornell and accommodates the modern approach for eliciting expertise and statistical treatment.

An updated probabilistic seismic hazard assessment (PSHA) for Pakistan
Bulletin of Earthquake Engineering, 2021In this study, an updated probabilistic seismic hazard assessment (PSHA) of Pakistan region is performed using the procedures developed for the US National Seismic Hazard Maps and the Earthquake Model of the Middle East (EMME14). It is based on the combination of conventional area sources model and the spatially smoothed gridded seismicity model with ...

Probability in PSHA: Reply to "Comment on 'PSHA Validated by Quasi-Observational Means' by Z. Wang"
Seismological Research Letters, 2012One of the attractions of the Monte Carlo simulation approach to seismic hazard is its conceptual simplicity and directness. What a site operator wants to know is what type of earthquake shaking his plant might possibly have to endure in its lifetime. In response, the seismologist takes all the available information on regional seismogenesis, distils ...
