A Unified Probabilistic Framework for Seismic Hazard Analysis
Bulletin of the Seismological Society of America, 2017The proper scientific interpretation of the seismic hazard estimates requires a probabilistic framework that admits epistemic uncertainties on aleatory variables. This is not straightforward because, to subjectivists, all probabilities are epistemic, whereas to frequentists, all probabilities are aleatory.We illustrate the inadequacy of purely ...

Probabilistic Seismic Hazard Analysis for Induced Seismicity
2014Probabilistic Seismic Hazard Analysis is currently the most common approach to seismic hazard analysis. For application to induced seismicity, a major challenge is the fact that the hazard is inherently nonstationary. In this paper we describe the theoretical extension of PSHA to a non-stationary context.

Probabilistic seismic hazard analysis in Nepal
Earthquake Engineering and Engineering Vibration, 2013The seismic ground motion hazard for Nepal has been estimated using a probabilistic approach. A catalogue of earthquakes has been compiled for Nepal and the surrounding region (latitude 26° N and 31.7° N and longitude 79° E and 90° E) from 1255 to 2011.

Improved seismic hazard model with application to probabilistic seismic demand analysis [PDF]
Earthquake Engineering and Structural Dynamics, 2007 An improved seismic hazard model for use in performance-based earthquake engineering is presented. The model is an improved approximation from the so-called 'power law' model, which is linear in log-log space. The mathematics of the model and uncertainty

On Uncertainties in Probabilistic Seismic Hazard Analysis
Earthquake Spectra, 2016Probabilistic seismic hazard analysis (PSHA) is, in essence, a method to deal with uncertainty, the importance of which justifies the use of a formal and rigorous background for its study. Therefore, the purpose of this paper is to contribute to the reflections on how to correctly handle uncertainty in PSHA.

Probabilistic seismic hazard analysis for Bangalore
Natural Hazards, 2008This article presents the results of probabilistic seismic hazard analysis (PSHA) for Bangalore, South India. Analyses have been carried out considering the seismotectonic parameters of the region covering a radius of 350 km keeping Bangalore as the center. Seismic hazard parameter ‘b’ has been evaluated considering the available earthquake data using (

Problems for Probabilistic Seismic Hazard Analysis
Natural Hazards, 1997The use of b-values derived from the Gutenberg–Richter relationship as a phenomenological base for developing probabilistic seismic hazard analyses (PSHA) has been questioned for years. The relationship is still used because political demands require something for PSHA, one variable is easy to deal with, and no persuasive alternative has come forward ...

Probabilistic seismic hazard analysis for seismic sequences
2013Earthquakes are typically clustered both in space and time. Seismic h azard , expressed in terms of rate of exceedance of a ground motion intensity measure , classically refers to ma i nshock s, which means that such a rate is computed filtering the rate o f occurrence of events of largest magnitude within each cluster of earthquakes.

Probabilistic seismic hazard analysis for a site
Nuclear Engineering and Design, 2006Traditionally, the seismic design basis ground motion has been specified by normalised response spectral shapes and peak ground acceleration (PGA). The mean recurrence interval (MRI) used to be computed for PGA only. The present work develops uniform hazard response spectra, i.e., spectra having the same MRI at all frequencies for Tarapur Atomic Power ...

The Hazard in Using Probabilistic Seismic Hazard Analysis for Engineering
Environmental & Engineering Geoscience, 1998Both the deterministic and probabilistic methods of seismic hazard analysis serve necessary purposes. Probability is needed to obtain operating basis earthquakes, to perform risk analyses, to prioritize projects, and for assigning recurrence estimates to deterministic earthquakes.
