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 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 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 کاملState of stress before and after the 1994 Northridge Earthquake
The state of tectonic stress in the epicentral area of the 17 January 1994, Northridge earthquake (Mw 6.7) is investigated by applying a stress inversion method to P-wave polarity data from earthquakes in Northridge from July 1981 to January 1994 and from the Northridge aftershocks during January 1994 to December 1995. A 3-D crustal model is used to trace the rays taking off from the hypocenter...
متن کاملThe magnitude 6.7 northridge, california, earthquake of 17 january 1994.
The most costly American earthquake since 1906 struck Los Angeles on 17 January 1994. The magnitude 6.7 Northridge earthquake resulted from more than 3 meters of reverse slip on a 15-kilometer-long south-dipping thrust fault that raised the Santa Susana mountains by as much as 70 centimeters. The fault appears to be truncated by the fault that broke in the 1971 San Fernando earthquake at a dept...
