Ground motion estimation for a site (34.01 o N, 71.45 o E) located in the Peshawar in terms of Peak Ground Acceleration (PGA) values is conducted. It is carried out with deterministic seismic hazard analysis approach using faults sources within a radius of one hundred kilometers around site. The results of this study indicate that the Main Boundary Thrust located at a distance of twenty nine (2...

In this paper, the probable range of the horizontal component of peak ground acceleration (PGA) is predicted as a function of focal depth, earthquake magnitude and epicentral distance, using artificial neural network (ANN). Three different ANN architectures (namely Feed Forward, Back Propagation and Radial Bias Networks) are used to develop the model. The three models are then compared, to deci...

This study was conducted to compare the performance of three different spatial analysis models: Inverse Distance Weighted (IDW), Ordinary Kriging,­­ and Regularized Spline interpolation technique determine best fit model representing Peak Ground Acceleration (PGA) in West Java Province, Indonesia. The models are commonly used visualization, but have calculation methods. calculations were perfor...

This study collects recorded ground motions from the near-source region of large earthquakes and considers to what extent this historic record can inform expectations of future ground motions at similar sites. The distribution of observed peak ground acceleration (PGA) is well approximated by the lognormal distribution, and we expect the observed distribution to remain unchanged with the additi...

Peak ground acceleration (PGA) plays an important role in assessing effects of earthquakes on the built environment, persons, and the natural environment. It is a basic parameter of seismic wave motion based on which earthquake resistant building design and construction are made. The level of damage is, among other factors, directly proportional to the severity of the ground acceleration, and i...
