TLDR
In this article, empirical response spectral attenuation relations for the average horizontal and vertical component for shallow earthquakes in active tectonic regions were derived using a database of 655 recordings from 58 earthquakes.Abstract:
Using a database of 655 recordings from 58 earthquakes, empirical response spectral attenuation relations are derived for the average horizontal and vertical component for shallow earthquakes in active tectonic regions. A new feature in this model is the inclusion of a factor to distinguish between ground motions on the hanging wall and footwall of dipping faults. The site response is explicitly allowed to be non-linear with a dependence on the rock peak acceleration level.read more

Simulation of Ground Motion Using the Stochastic Method
TL;DR: One of the essential characteristics of the method is that it distills what is known about the various factors affecting ground motions into simple functional forms that can be incorporated into practical predictions of ground motion.

Modification of Empirical Strong Ground Motion Attenuation Relations to Include the Amplitude and Duration Effects of Rupture Directivity
TL;DR: In this article, the authors developed modifications to empirical strong ground motion attenuation relations to account for the effects of rupture directivity on strong motion amplitudes and durations, based on an empirical analysis of near-fault data.

An NGA Model for the Average Horizontal Component of Peak Ground Motion and Response Spectra
TL;DR: In this article, a model for estimating horizontal ground motion amplitudes caused by shallow crustal earthquakes occurring in active tectonic environments is presented, which provides predictive relationships for the orientation-independent average horizontal component of ground motions.

TL;DR: One of the alternative ground-motion intensity measures introduced in this paper is found to be relatively efficient and sufficient for the range of buildings considered and for both the near-source and ordinary ground motions.

Equations for Estimating Horizontal Response Spectra and Peak Acceleration from Western North American Earthquakes: A Summary of Recent Work
TL;DR: In this article, the authors provide tables for estimating random horizontal component peak acceleration and 5 percent damped pseudo-acceleration response spectra in terms of the natural, rather than common, logarithm of the ground-motion parameter.

Estimation of response spectra and peak accelerations from western north american earthquakes: an interim report part 2
TL;DR: For example, Joyner and Boore as mentioned in this paper used a two-stage regression method to fit a functional form to empirical data using two-component recordings from 20 earthquakes to develop the equations for peak acceleration.

Magnitude-dependent variance of peak ground acceleration
TL;DR: This article examined the variability of peak horizontal and vertical accelerations of the large California strong motion data set for the time period 1957 to 1991 and found a statistically significant dependence of the standard error on earthquake magnitude.
