Parallel Finite Element Modeling of Earthquake Ground Response and Liquefaction
Parallel computing is a promising approach to alleviate the computational demand in conducting largescale finite element analyses. This paper presents a numerical modeling approach for earthquake ground response and liquefaction using the parallel nonlinear finite element program, ParCYCLIC, which is designed for distributed-memory message-passing parallel computer systems. In ParCYCLIC, finite...
متن کاملObservation of the seismic nucleation phase in the Ridgecrest, California, earthquake sequence
Near-source observations of five M 3.8-5.2 earthquakes near Ridgecrest, California are consistent with the presence of a seismic nucleation phase. These earthquakes start abruptly, but then slow or stop before rapidly growing again toward their maximum rate of moment release. Deconvolution of instrument and path effects by empirical Green's functions demonstrates that the initial complexity at ...
متن کاملVariability of Ground Motions in Southern California the 1995 to 1996 Ridgecrest Sequence
Seismograms from the 1995 to 1996 Ridgecrest, California, earthquake sequence, recorded by the TriNet digital seismic network, provide high-quality waveforms from sites throughout southern California, including sites in markedly heterogeneous areas like the Los Angeles area sedimentary basins. Synthetic seismograms calculated by the refiectivity method with various 1D models are used as a basel...
متن کاملInitial rupture of earthquakes m the 1995 Ridgecrest , California sequence
Close examination of the P waves from earthquakes ranging in size across several orders of magnitude shows that the shape of the initiation of the velocity waveforms is independent of the magnitude of the earthquake. A model in which earthquakes of all sizes have similar rupture initiation can explain the data. This suggests that it is difficult to estimate the eventual size of an earthquake fr...
متن کاملChapter 2 Literature Review on Liquefaction and Ground Densification for Liquefaction Mitigation
One of the most dramatic causes of damage of structures during earthquakes has been the development of liquefaction in saturated cohesionless deposits. These deposits have tendency to densify when subjected to earthquake loading. However, when saturated, the tendency to densify causes the excess pore water pressure to increase. This, in turn, results in the effective stress of soil to decrease....
