Ground Motion Examples from the European Ground Motion Service
IGARSS 2022 - 2022 IEEE International Geoscience and Remote Sensing Symposium, 2022The Copernicus European Ground Motion Service (EGMS) provides consistent, regular, standardised, harmonised and reliable information regarding natural and anthropogenic ground motion phenomena over the Copernicus Participating States and across national borders, with millimetre accuracy.

Regional Ground-Motion Simulation Using Recorded Ground Motions
Bulletin of the Seismological Society of America, 2021ABSTRACT Regional ground-motion simulation is important for postearthquake seismic damage assessment. Herein, a ground-motion simulation method using recorded ground motions is proposed. Inverse-distance-weighted interpolation of the response spectra is performed to obtain the response spectrum at the target location.

Annual Review of Earth and Planetary Sciences, 1988
In this review, we discuss some of the many phenomena that can determine the nature of strong ground motion. Some of these phenomena have been inferred from the study of existing ground-motion records, and others are inferred from theoretical models of earthquake sources and wave propagation.

The availability of empirical strong ground motion data will always be less that what would be needed to meet the needs of a variety of ever demanding engineering problems. A set of strong ground motions, either recorded or theoretically simulated, is the necessary database for the civil engineering design, regarding both new construction and ...

Pure and Applied Geophysics, 2019
Two approaches are used to develop the vertical design spectra in probabilistic seismic hazard assessment (PSHA): (i) performing PSHA for the vertical component using vertical ground motion models (GMMs), and (ii) utilizing the V/H ratio GMMs to scale the horizontal spectrum during or after the hazard calculations for the horizontal component.

Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008
The current state-of-the-art ground motion models for application to the United States is summarized. The recent NGA ground motion models for shallow crustal earthquakes are in much more advanced than the currently available models for subduction earthquakes and for stable continental regions.

Earthquakes, Strong-Ground Motion
2011Earthquake ground motion is a natural phenomenon associ- ated with a sudden release of energy due to a fault rupture. Strong-motion seismology deals with seismic waves radiated by large earthquakes. More precisely, it is concerned with measurement, interpretation and prediction of strong shaking generated by damaging earthquakes.

When an earthquake happens, the seismic wave produced by the seismic source is a time-dependent process. Through the propagation in the earth media, the wave shape will undergo complex changes. For a given site, the ground motion can be characterized by the time history of ground motion displacements, velocities or accelerations.
