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.

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 ...

Strong Ground Motion Prediction Using Virtual Earthquakes
Science, 2014Sedimentary basins increase the damaging effects of earthquakes by trapping and amplifying seismic waves. Simulations of seismic wave propagation in sedimentary basins capture this effect; however, there exists no method to validate these results for earthquakes that have not yet occurred.

Characterization of Earthquake Strong Ground Motion
Pure and Applied Geophysics, 2003Some underwater landslides are triggered by strong ground motions caused by earthquakes. This paper reviews current concepts and trends in the characterization of strong ground motion. Improved empirical ground motion models have been derived from a strong motion data set that has grown markedly over the past decade.

Bulletin of the Seismological Society of America, 2006
Most instruments used in seismological practice to record ground mo- tion are pendulum seismographs, velocigraphs, or accelerographs. In most cases it is assumed that seismic instruments are only sensitive to the translational motion of the instrument's base.

CHAOTIC CHARACTERISTIC ANALYSIS OF STRONG EARTHQUAKE GROUND MOTIONS
International Journal of Bifurcation and Chaos, 2012This paper aims to analyze and understand the irregularity and complexity of earthquake ground motions from the perspective of nonlinear dynamics. Chaotic dynamics theory and chaotic time series analysis are suggested to examine the nonlinear dynamical characteristic of strong earthquake ground motions.

New Brunswick strong ground motion records
Physics of the Earth and Planetary Interiors, 1985Abstract Although large earthquakes including several of magnitude 7 are known to have occurred in eastern Canada since the arrival of European settlers in the 16th century, no significant strong ground motion records were available until 1982, and earthquake engineering design relies on extrapolation of results from mostly California data, modified ...

Strong Ground Motion from the Michoacan, Mexico, Earthquake
Science, 1986The network of strong motion accelerographs in Mexico includes instruments that were installed, under an international cooperative research program, in sites selected for the high potential of a large earthquake. The 19 September 1985 earthquake (magnitude 8.1) occurred in a seismic gap where an earthquake was expected.

Directionality of Strong Ground Motion Durations
2014Directionality of ground motions is an important aspect to be considered in seismic design and is incorporated in the Pacific Earthquake Engineering Research (PEER) center’s Next Generation Attenuation Ground Motions (NGA) projects and ASCE7-10. However, the NGA models and ASCE7-10 are limited to ground motion response spectra.
