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.

Attenuation of peak ground accelerations from the great Wenchuan earthquake

Earthquake Engineering and Engineering Vibration, 2009
Over 800 accelerograms recorded by 272 ground-level stations during the Wenchuan earthquake are used to analyze the influence of rupture distance, local site conditions and azimuth on peak ground accelerations (PGAs). To achieve a better understanding of the characteristics of ground motions, the spatial distributions of the EW, NS and UD components of

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 ...

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.

Uncertainty in the estimates of peak ground acceleration in seismic hazard analysis

Izvestiya, Physics of the Solid Earth, 2015
Probabilistic seismic hazard analysis has become a standard procedure preceding the antiseismic construction. An important component of the relevant calculations is the allowance for the uncertainty in the strong motion parameters (e.g., peak ground acceleration (PGA)).

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.
