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 کاملGPS seismology
GPS seismology uses convential geodetic models to analyze GPS data at high sampling rates, such as 1 Hz. GPS seismology results are shown for the Denali, San Simeon, Tokachi-oki, and Chuetsu earthquakes. Records for these earthquakes indicate that GPS is an excellent instrument for measuring large displacements near earthquake ruptures. GPS systems can be improved for seismic applications if th...
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...
متن کاملStrong Approximation of Brownian Motion
Simple random walk and Brownian motion are two strongly interconnected mathematical concepts. They are widely involved in not only pure math, but also in many other scientific fields. In this paper I will first introduce and define some basic concepts of discrete-time random walk. Then I will construct Brownian Motion with some basic properties, and use a method called the strong approximation ...
