New source spectral model and strong ground motion simulation of the 1994 M6.7 Northridge earthquake
ABSTRACT: This paper checked, appended and corrected the strong motion database of Western U.S. on site conditions and so on first, and then recommends a new source spectral model and model parameters depending on the statistical analysis to acceleration Fourier spectra of these strong motion recordings. The new source spectral model has some further improvement to Brune ω 2 model and Atkinson ...
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 کاملStochastic Finite-Fault Modeling of Ground Motions from the 1994 Northridge, California, Earthquake. I. Validation on Rock Sites
The stochastic method of simulating ground motions from finite faults is validated against strong-motion data from the M 6.7 1994 Northridge, California, earthquake. The finite-fault plane is subdivided into elements, each element is assigned a stochastic o92 spectrum, and the delayed contributions from all subfaults are summed in the time domain. Simulated horizontal acceleration time historie...
متن کاملThe Slip History of the 1994 Northridge , California , Earthquake Determined from Strong - Motion , Teleseismic , GPS , and Leveling Data
We present a rupture model of the Northridge earthquake, determined from the joint inversion of near-source strong ground motion recordings, P and SH teleseismic body waves, Global Positioning System (GPS) displacement vectors, and permanent uplift measured along leveling lines. The fault is defined to strike 122 ° and dip 40 ° to the south-southwest. The average rake vector is determined to be...
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 ...
