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 ...

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.

On the Strong Ground Motion Attenuation in Spain
Bulletin of the Seismological Society of America, 2008In the last two decades, all earthquake hazard studies in Spain have been done using the attenuation deduced from the isoseismal maps of the most important earthquakes. However, it is well known that the preferred parameter to measure the size of any shock is magnitude and, consequently, the knowledge of acceleration as a function of magnitude and ...

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.

The Prediction of Strong Ground Motion
1987The prediction of motion for use in engineering design must rely both on empirical and theoretical methods. The methods complement on another, for the empirical analyses provide checks on the theory and help to determine the parameters necessary in the theoretical predictions.

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.

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.

Curvograms of Strong Earthquake Ground Motion
Journal of Engineering Mechanics, 1990A method for the synthetic generation of curvograms (curvature versus time) associated with strong earthquake shaking is presented. It is shown that small radii of curvative of ground motion, in the range of several hundred meters, are possible only for very large accelerations (1–3 ge/u), near epicenter, and in soft geologic and soil environment, with
