Achievements of strong motion seismology in 20 century and its future directions
We have been trying to make a recipe for predicting ground motions from future large earthquakes. To do that the most important factors are the source characterizations for complex rupture processes and the Green’s function estimations for realistic geological structures. We attempt to formulate the source characterizations based on recent results of the waveform source inversion. There are two...
متن کاملImpact of Broadband Seismology on the Understanding of Strong Motions
Most analyses of strong motion attenuation assume simple whole-space type geometrical spreading, namely (1 /R ) or its modified form e kR/R. HOWever, broadband data presently becoming available suggests a more complex behavior with substantial crustal effects. Events such as the Sierra Madre event, M = 5.8, triggered the strong motion channels at all of the TERRAscope stations allowing for 0.01...
متن کاملAPPLICATION OF WAVELET THEORY IN DETERMINING OF STRONG GROUND MOTION PARAMETERS
Cumulative absolute velocity (CAV), Arias intensity (AI), and characteristic intensity (CI) are measurable characteristics to show collapse potential of structures, evaluation of earth movement magnitude, and detection of structural failure in an earthquake. In this paper, parameters which describe three characteristics of ground motion have been investigated by using wavelet transforms (WT). I...
متن کاملA Strong Ground Motion Catalogue of Selected Records for Shallow Crustal, Near Field Earthquakes in Iran
Understanding strong ground motions in the near-fault areas is important for seismic risk assessment in densely populated areas. In the past, lack of information on strong ground motion for large and moderate earthquakes led to the use of mainly far field large and moderate earthquake records in equations for calculation of the strong ground motion parameters. In this article, we collected and ...
متن کاملTilts in Strong Ground Motion
Most instruments used in seismological practice to record ground motion 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. In this study the full equation of pendulum motion, including the inputs of rotations and tilts, is considered. It is shown that tilting th...
