Probabilistic seismic hazard assessment without source characterization

2010
Conventional Probabilistic Seismic Hazard Assessment (PSHA) is difficult to apply in regions lacking sufficient information of the geological setting, active faults, and so forth. Also, for a site-specific PSHA, site effects arising from both crustal rock and overlying soil sediments are generally not assessed rigorously.

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.

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 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

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 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

Probabilistic Seismic Hazard Assessment Methodology for Distributed Seismicity

Bulletin of the Seismological Society of America, 2003
This study deals with probabilistic seismic hazard analysis (PSHA) based on earthquakes that cannot be assigned to specific geologic structures (distributed seismicity). To calculate seismic hazard from distributed seismicity, the PSHA methodology is extended in numerous ways. A simple quantitative seismotectonic model enables statistical incorporation

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 ...
