The Motion of the Ground in Earthquakes
Scientific American, 1977The slippage along a fault that produces an earthquake radiates seismic waves; the manner in which these waves shake the ground bears on the design of buildings and other structures in the earthquake zones. Since seismic waves span such a broad spectrum of period and amplitude, many different kinds of instruments and experimental techniques are needed ...

Pure and Applied Geophysics, 2019
The main objectives of this study are: (1) to choose the vertical ground motion models (GMMs) that are consistent with the magnitude, distance, depth, and site amplification scaling of the updated Turkish ground motion database, and (2) to combine the vertical GMMs with the V/H ratio models selected in the accompanying paper (Alipour et al.

Evaluation of ground motion selection and modification procedures using synthetic ground motions
Earthquake Engineering & Structural Dynamics, 2015SummaryThis study presents a novel approach for evaluating ground motion selection and modification (GMSM) procedures in the context of probabilistic seismic demand analysis. In essence, synthetic ground motions are employed to derive the benchmark seismic demand hazard curve (SDHC), for any structure and response quantity of interest, and to establish

Stochastic Ground Motion Simulation
2014Strong earthquake ground motion records are fundamental in engineering applications. Ground motion time series are used in ▶ response-history dynamic analysis of structural or geotechnical systems. In such analysis, the validity of predicted responses depends on the validity of the input excitations.

Tuning of stochastic ground motion models for compatibility with ground motion prediction equations
Earthquake Engineering & Structural Dynamics, 2015SummaryStochastic ground motion models can facilitate a versatile description of earthquake acceleration time‐histories by modulating a white‐noise sequence through functions that address spectral and temporal properties of the excitation. This is established by relating the parameters of these functions to earthquake and site characteristics through ...

To determine the location of an earthquake occurrence, two geometric notations, namely hypocenter and epicenter, will be introduced first. Because the majority of earthquakes are caused by the rupture of the rock along a fault or multiple faults, and thousands of square kilometers of fault plane surface may be involved in this rupture, while it is ...

Amplification of Earthquake Ground Motions by Surface Ground
2019This chapter introduces the amplification of seismic ground motion by surface ground. A calculation method for the amplification magnification of the acceleration due to surface grounds \( G_{s} \) is presented and a concrete calculation example is shown.

, 2021 The Nature of Earthquake Ground Motion
1989The aim of this chapter is to provide a basic understanding about earthquakes, their world-wide distribution, what causes them, their likely damage mechanisms, earthquake measuring scales, and current efforts on the prediction of strong seismic ground motions. This chapter, therefore, furnishes the basic information necessary for understanding the more
