Probabilistic seismic hazard assessment for Singapore

Natural Hazards, 2020
Seismic hazard assessment of metropolitan areas is an important topic in catastrophe risk management and disaster prevention. In this study, a probabilistic seismic hazard analysis (PSHA) is performed to estimate the seismic hazard for Singapore. The PSHA approach has been conducted based on the OpenQuake engine.

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 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

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

Probabilistic Seismic Hazard Assessment of India

Seismological Research Letters, 2012
Online material : Data files for seismogenic source zones (polygons), smoothed-gridded seismicity models, and hazard curves at 0.2° regular grid spacing over the study region. Earthquake disasters occur mainly due to the collapse of buildings and structures triggered by ground motions.

A probabilistic assessment of the seismic hazard in Turkey

Tectonophysics, 1985
Abstract Seismic hazard maps for Turkey are developed by utilizing the current probabilistic procedures. The maps contain probabilistic estimates of the maximum MSK intensity and the maximum horizontal peak ground acceleration for the return periods of 225, 475 and 10,000 years.

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,

PROBABILISTIC SEISMIC HAZARD MAPS OF THAILAND

Journal of Earthquake and Tsunami, 2010
In this study, the probabilistic seismic hazard map of Thailand and neighboring areas is developed. Thailand is located close to the Andaman thrust in the west and the Sunda arc in the south which are the boundaries between the Eurasian plate and Indo-Australian plate. Several active faults in this region have caused earthquakes which affects Thailand.

Probabilistic Seismic-Hazard Assessment for Portugal

Bulletin of the Seismological Society of America, 2007
The probabilistic seismic hazard of Portugal is analyzed with a logic tree approach. A critical part of the work was the review of the seismic catalog and the moment magnitude (M) estimation for historical earthquakes. To produce a cat- alog with a uniform magnitude scale, the instrumental magnitudes were converted to M through empirical relations. Two

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 ...
