Error inflation in Probabilistic Seismic Hazard Analysis

Engineering Geology, 2007
Based on a consistent interpretation of earthquake occurrence as a stochastic process I demonstrate that the mathematical model of Probabilistic Seismic Hazard Analysis (PSHA) as it is in use today is inaccurate and leads to systematic errors in the calculation process.

Seismic zonation of Nepal using probabilistic seismic hazard analysis

Arabian Journal of Geosciences, 2021
Probabilistic 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, 2014
Abstract 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, 2016
Abstract 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, 2013
The 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

2014
Probabilistic 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, 1997
The 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, 2018
Over 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 ...
