ARTIFICIAL NEURAL NETWORK BASED ESTIMATION OF PEAK GROUND ACCELERATION

ISET Journal of Earthquake Technology, 2009
This paper presents the application of artificial neural networks (ANN) for estimation of peak ground acceleration (PGA) for earthquakes of magnitude more than 5.0 and hypocentral distance of less than 50 km. Earthquake magnitude, hypocentral distance, and average values of four geophysical properties of the site (Standard Penetration Test (SPT) blow ...

Prediction of Peak ground acceleration for earthquakes by using intelligent methods

2017 5th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS), 2017
Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location and the design basis earthquake ground motion is often defined in terms of PGA. In this paper, three intelligent methods are proposed for predicting of PGA in regions where PGA value is greater than 0.5g. These knowledge base

A Theoretical Study of the Dependence of the Peak Ground Acceleration on Source and Structure Parameters

1987
The attenuation laws of peak ground acceleration (PGA) and root mean square acceleration (arms) are theoretically simulated for 6 differently laterally homogeneous models of the lithosphere. The anelastic properties of the structures are parametrized by quality factors.

Empirical Near-Source Attenuation Relationships for Horizontal and Vertical Components of Peak Ground Acceleration, Peak Ground Velocity, and Pseudo-Absolute Acceleration Response Spectra

Seismological Research Letters, 1997
Based on extensive user feedback, it has been determined that there are several errors and ambiguities that need to be corrected in the original manuscript (Campbell, 1997). Some of the errors are the result of typographical errors by the publisher, while others are omissions to the original equations that occurred as an oversight.

Estimation of the Peak Ground Acceleration for Eastern Turkey

2019
The peak ground acceleration (PGA) is significant parameter for earthquake hazard assessments. Therefore attenuation relationships have been developed for calculating PGA according to strong-motion databases. Generally this relation has been related to the earthquake magnitude and epicenter distance.
