Seismic Hazard Analysis with Randomly Located Sources

Natural Hazards, 1994
Demarcation 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 ...

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).

Seismic hazard analysis: How to measure uncertainty?

Computers & Structures, 1998
Summary: 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, 1988
Two 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

2011
In 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,

Seismic hazard analysis: a comparative study

Canadian Journal of Civil Engineering, 2006
The quantitative seismic hazard maps for the 1970s National Building Code of Canada were evaluated using the Davenport–Milne method. The Cornell–McGuire method is employed to develop recent seismic hazard maps of Canada. These methods incorporate the information on seismicity, magnitude-recurrence relations, and ground motion (or response) attenuation ...

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.

The Hazard in Using Probabilistic Seismic Hazard Analysis for Engineering

Environmental & Engineering Geoscience, 1998
Both 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.

Geological analysis and seismic hazard in the Central Apennines (Italy)

Journal of Geodynamics, 2000
Abstract This study puts forward a segmentation model applied to active faults with the aim of assessing seismic hazard in the Central Apennines. The model, whose reliability had been ascertained during the 1997 Umbria–Marche earthquake sequence, also implies a review of the key terms used in the analysis of active faults and points out the need for ...
