Source rupture process of the 2011 Tohoku - Oki earthquake derived from the strong - motion records
We reveal the source rupture process using the strong-motion data by the inversion analysis. The derived slip distribution shows one prominently large slip area extending from the hypocentre area to the shallow part of the fault along the trench axis, which is located far off the coastal region extensively damaged by the tsunamis. The shallow main rupture started 60 seconds after the initial br...
متن کاملVariations of Strong Earthquake Ground Motion In
Accelerograms recorded at six stations in the metropolitan Los Angeles area during the Borrego Mountain, 1968, the Lytle Creek, 1970, and the San Fernando, 1971, earthquakes in southern California have been studied. In comparing the ground motions recorded during different earthquakes at each of the six stations and in correlations of these motions recorded at different stations during the same...

متن کاملSimulation of earthquake rupture process and strong ground motion
Computer simulation of the strong ground motion generated from the earthquake•rupture process on a shallow strike-slip fault are carried out by using a 3-D finite difference method. The faulting process is modeled using a dynamic crack model with fixed rupture velocity or with finite-stress-fracture criterion. The near-source ground motion is sensitive to the details of sliprate or slip-acceler...
متن کاملFuzzy logic-based attenuation relationships of strong motion earthquake records
Fuzzy logic techniques have been widely used in civil and earthquake engineering applications in the past four decades. However, no thorough research studies were conducted to use them for deriving attenuation relationships for peak ground accelerations (PGA). This paper is an attempt to fill this gap by employing a fuzzy approach with fuzzy sets for earthquake magnitude and distance from sourc...
