The 1999 İzmit, Turkey, Earthquake: Nonplanar Fault Structure, Dynamic Rupture Process, and Strong Ground Motion
We simulated dynamic rupture propagation along various nonplanar fault models of the 1999 İzmit, Turkey, earthquake using a boundary integral equation method. These models were inferred from geological and geodetic observations. Based on these results, we modeled seismic-wave propagation around the fault system using a finite difference method. We focused on the effect of different fault geomet...
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 کاملRupture, waves and earthquakes
Normally, an earthquake is considered as a phenomenon of wave energy radiation by rupture (fracture) of solid Earth. However, the physics of dynamic process around seismic sources, which may play a crucial role in the occurrence of earthquakes and generation of strong waves, has not been fully understood yet. Instead, much of former investigation in seismology evaluated earthquake characteristi...
متن کاملRupture Process of Subduction-Zone Earthquakes
This review is primarily concerned with the rupture process of large subduction-zone earthquakes determined by various seismological methods, and with its interpretation in terms of an asperity model. It is not possible to make a thorough and extensive review on the subject because of the limited length. Consequently, this review is inevitably biased toward the works in which I was directly inv...
متن کاملSpectra of Great Earthquakes : Teleseismic Constraints on Rupture Process and Strong Motion
Short-period body waves recorded at teleseismic distances from great earth· quakes provide information about source rupture processes and strong motions. First, we examine mostly WWSSN records of 19 earthquakes of moment magni· tude Mw of 6.5 to 9.5. Four parameters are measured from the short-period Pwave train: the maximum amplitude; the period at maximum amplitude; the time between the first...
