Seismic zonation of Nepal using probabilistic seismic hazard analysis
Arabian Journal of Geosciences, 2021Probabilistic seismic hazard of Nepal (PSHA) followed by seismic zonation is carried out for enclosed polygon within 26.5°N–30.5°N latitude and 80°E–89°E longitude. Mixed type of ground motion prediction equations (GMPEs) derived for active shallow crustal and subduction interference with areal and linear sources was used by logic tree approach.

Sequence-Based Probabilistic Seismic Hazard Analysis
Bulletin of the Seismological Society of America, 2014Abstract Earthquakes are typically clustered both in space and time. Only mainshocks, the largest magnitude events within each cluster, are considered by classical seismic hazard, which is expressed in terms of rate of exceedance of a ground‐motion intensity measure at a site of interest (Cornell, 1968).

On Multisite Probabilistic Seismic Hazard Analysis
Bulletin of the Seismological Society of America, 2016Abstract Seismic hazard assessment, in its classical format, models the stochastic process of occurrence of earthquakes causing the exceedance of ground‐motion intensity measure (IM) thresholds at a specific site. This is because civil structures typically require probabilistic seismic hazard analysis (PSHA) for one location.

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.

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.

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 Code Verification
PEER Reports, 2018Over the past decade, the use of Probabilistic Seismic Hazard Analysis (PSHA) to assess seismic hazards has expanded, leading to the creation of a number of new PSHA computer codes throughout the industry. Additionally, recent seismic source and ground-motion characterization studies have led to more complex source and ground-motion models, which ...

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 (

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 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.
