An evolutionary model for earthquake ground motion
Structural Safety, 1989Abstract A simple and versatile evolutionary random process model for describing the earthquake ground motion is proposed. The model is composed of individually modulated component stationary processes, each component representing the energy in the process in a narrow band of frequencies.

Arma models for earthquake ground motions
Earthquake Engineering & Structural Dynamics, 1982AbstractThis paper outlines the use of discrete, autoregressive/moving‐average (ARMA) models for identification and estimation of parameters in models derived from analysis of uniformly digitized earthquake ground motion acceleration data. Such models are of equal generality as compared to continuous‐time models and have a number of significant ...

The Barrier Model and Strong Ground Motion
Pure and Applied Geophysics, 2003An overview of the most important developments in Engineering (or Strong Motion) Seismology is presented alongside Professor Keiiti Aki’s contributions, who is one of the founders of this field. The mechanics of earthquake rupture are discussed with due emphasis on the various physical phenomena. The presentation is made in a tutorial manner, borrowing

A Nonergodic Ground-Motion Model for Türkiye
Bulletin of the Seismological Society of AmericaABSTRACT Existing ground-motion models (GMMs) for Türkiye have primarily relied on ergodic or partially nonergodic frameworks, which are limited in capturing systematic ground-motion characteristics and the trade-off between aleatory and epistemic uncertainties.

The Variability of Ground-Motion Prediction Models and Its Components
Seismological Research Letters, 2010Modern ground-motion prediction models use datasets of recorded ground-motion parameters at multiple stations during different earthquakes and in various source regions to generate equations that are later used to predict site-specific ground motions.

Modeling the Motion of Ground Water and the Migration of Radionuclides in the Soil
International Journal of Fluid Mechanics Research, 1996The article presents a generalized formulation of a mathematical model of migration of dissolved substances in soils with allowance for their absorption by the plant root. A thin inhomogeneous layer is modeled by piecewise-smooth n-dimensional vector functions.

Modeling of Ground Motion at Napoli for the 1688 Scenario Earthquake
Pure and Applied Geophysics, 2010The Sannio seismogenic area turns out to be responsible for the highest peak ground accelerations (PGA) and seismic response spectra (SRS) at Napoli. The 1688 earthquake is considered representative of the area, and realistic synthetic seis- mograms have been computed for this scenario earthquake at the historical center and the eastern sector of ...

Generative Modeling of Earthquake Ground Motion
Reliable earthquake ground-motion time histories are essential for seismic hazard analysis, structural design, and the risk assessment of distributed infrastructure systems. However, observed records of large earthquakes remain sparse, while physics-based simulations are computationally expensive and difficult to deploy at the scale required for ...openaire +1 more source
