SEISMIC HAZARD ANALYSIS FOR MYANMAR
Journal of Earthquake and Tsunami, 2013In 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

The Effect of Seismic Sequences in Probabilistic Seismic Hazard Analysis
Bulletin of the Seismological Society of America, 2022ABSTRACTTraditionally, probabilistic seismic hazard analysis (PSHA) considers only mainshock events and models their temporal occurrence through a homogeneous Poisson process. Thus, it disregards foreshocks and aftershocks, assuming they have a minor effect on PSHA.

Seismic Hazard Analysis of Lifelines
Journal of the Structural Division, 1982Methods 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
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.

Seismic Hazard and Risk Analysis
2021Seismic hazard and risk analyses underpin the loadings prescribed by engineering design codes, the decisions by asset owners to retrofit structures, the pricing of insurance policies, and many other activities. This is a comprehensive overview of the principles and procedures behind seismic hazard and risk analysis.

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 ...

Seismic Hazard Analysis with Randomly Located Sources
Natural Hazards, 1994Demarcation of areal and linear seismic sources involves a certain degree of uncertainty and this should be reflected in the final seismic hazard results. The uncertainty associated with the description of the geographical coordinates of a source zone boundary is modeled by introducing the concept of ‘random boundary’, where the location of the ...

Seismic hazard analysis: How to measure uncertainty?
Computers & Structures, 1998Summary: Applications of probabilistic seismic hazard analysis demand the adoption of a model (i.e. of the forms of a certain number of correlations and probabilistic distributions) and the estimate of the parameters of the model. As a measure of uncertainty in the calculation of the expected value of a given quantity (for instance the peak ground ...

Seismic hazard analysis for the Philippines
Natural Hazards, 1988Two sample probabilistic hazard maps for the Philippine Region are compiled. In these are shown various levels of expected horizontal ground acceleration for some given annual probability of exceedence, namely, for 0.1% a.p.e. and for 0.01% a.p.e. Such hazard maps are needed by structural engineers for compiling seismic zoning maps. The hazard maps are

A new procedure for probabilistic seismic hazard analysis
2011In the Performance-Based Seismic Design framework, the development of an appropriate “Probabilistic Seismic Hazard Analysis” which allows to statistically characterize the seismic input at the site of an engineering project becomes of crucial importance. The objective of the hazard analysis is to compute, for a given site over a given observation time,
