Seismic Hazard Analysis

2018
This chapter highlights the significance of Ground Motion Prediction Equations to estimate the seismic hazard at a region based on earthquake magnitude and source to site distance. A glimpse of both deterministic and probabilistic approaches for hazard assessment is presented along with a discussion on the logic tree framework.

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 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.

SEISMIC HAZARD ANALYSIS FOR MYANMAR

Journal of Earthquake and Tsunami, 2013
In this study, the seismic hazards of Myanmar are analyzed based on both deterministic and probabilistic scenarios. The area of the Sumatra–Andaman Subduction Zone is newly defined and the lines of faults proposed previously are grouped into nine earthquake sources that might affect the Myanmar region. The earthquake parameters required for the seismic

Seismic hazard analysis of Peru

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1992
Abstract This paper provides a hazard map of Peru, showing peak ground acceleration (PGA) levels on bedrock, with a 10% probability of exceedance for a 50 yr time period. The probabilistic PGA map for Peru and adjacent areas may be used as a reference by designers and engineers to obtain the primary input for initially quantifying seismic loads ...

Seismic hazard analysis—Computer validation

Computers & Structures, 1996
The purpose of this paper is to discuss the validation procedures used for validating a computer model developed for seismic hazard analysis. An elaborate and detailed computer model ([1] J. M. Ferritto, seismic hazard analysis, users guide #UG-0027, NCEL, Port Hueneme (1993)) was developed at the Naval Civil Engineering Laboratory (NCEL), Port Hueneme,

Seismic Hazard Analysis of Lifelines

Journal of the Structural Division, 1982
Methods for assessing the seismic safety of a lifeline system are developed; with part of the study being devoted to the development of a relation between the earthquake intensity and the distance for near-source regions. The attenuation of maximum ground motion intensity with distance is examined.

Probabilistic seismic hazard analysis for seismic sequences

2013
Earthquakes 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 Induced Seismicity

2020
In recent times, there has been increased seismicity in geologically stable basins in North America, thought to be associated with hydraulic fracturing and/or waste water disposal activities. Induced events could generate a seismic hazard higher than natural seismicity, particularly in areas with small-to-moderate natural background seismicity, leading
