Strong Ground Motion Estimation [PDF]

open access: yes, 2012
This progressive sequence of ground motion surprises suggests that the current state ofknowledge in strong motion seismology is probably not adequate to make unequivocal strong ground motion predictions. However, with these caveats in mind, strong ground motion estimation provides substantial value by reducing risks associated with earthquakes and ...

Modelling strong seismic ground motion: three-dimensional loading path versus wavefield polarization [PDF]

open access: yes, 2012
Seismic waves due to strong earthquakes propagating in surficial soil layers may both reduce soil stiffness and increase the energy dissipation into the soil.

Seismic site classification from the horizontal-to-vertical response spectral ratios: use of the Spanish strong-motion database [PDF]

open access: yes, 2019
Normally, the average of the horizontal-to-vertical (H/V) ratios of the 5% damped response spectra of ground motions is used to classify the site of strong-motion stations. In these cases, only the three-orthogonal as-recorded acceleration components are

Stochastic Simulation of Strong Ground Motions From Two M > 5 Uttarakhand Earthquakes

open access: yesFrontiers in Earth Science, 2021
Many studies based on the geodetic data and statistical analysis of seismicity have pointed out that sufficient amount of stress accumulated in the Himalayan plate boundary may host a big earthquake.

Simulation of strong ground motions [PDF]

open access: yesBulletin of the Seismological Society of America, 1980
abstractThe estimation of potential strong ground motions at short epicentral distances (Δ = 10 to 25 km) resulting from large earthquakes, M ≧ 6.5, generally requires extrapolation of a limited data set. The goal of this project has been to quantify the extrapolation through a simulation technique that relies heavily upon the more extensive data set ...

Near-field horizontal and vertical earthquake ground motions [PDF]

open access: yes, 2003
Strong-motion attenuation relationships are presented for peak ground acceleration, spectral acceleration, energy density, maximum absolute input energy for horizontal and vertical directions and for the ratio of vertical to horizontal of these ground ...

Performance of NGA Models in Predicting Ground Motion Parameters of The Strong Earthquake

open access: yesJournal of the Civil Engineering Forum, 2019
Next Generation Attenuation (NGA) West 1 and 2 models are employed to predict the ground motion parameters of strong earthquake during the 6.9 Mw Kobe Earthquake in 1995.
