Evidence for fault lubrication during the 1999 Chi-Chi, Taiwan, earthquake (Mw7.6)
[1] The ground motion data of the 1999 Chi-Chi, Taiwan, earthquake exhibit a striking difference in frequency content between the north and south portions of the rupture zone. In the north, the ground motion is dominated by large lowfrequency displacements with relatively small high-frequency accelerations. The pattern is opposite in the south,with smaller displacements and larger accelerations...
متن کاملFault Rupture Process of the 20 September 1999 Chi - Chi , Taiwan , Earthquake
We modeled the source rupture process of the 20 September 1999 ChiChi, Taiwan, earthquake (Mw 7.6) using an integrated dataset of near-field strong ground motion and Global Positioning System observations. This large inland thrust earthquake produced a surface break more than 80 km long along the Chelungpu fault. The event triggered over 700 strong-motion instruments on the island of Taiwan. Th...
متن کاملFinite fault inversion of the September 25, 1999 (Mw = 6.4) Taiwan earthquake: Implications for GPS displacements of Chi-Chi, Taiwan earthquake sequence
[1] The September 25, 1999 Chi-Chi Taiwan aftershock (Mw=6.4) occurred on a down dip extension of the fault ruptured in the mainshock. Strong motion data were used to invert for the finite-source process and test for the causative fault plane. We performed a grid-search over a range of focal mechanisms and found a preferred model (strike=5 , dip=30 , slip=100 ) different from teleseismic studie...

متن کاملPostseismic deformation following the 1999 Chi-Chi earthquake, Taiwan: Implication for lower-crust rheology
[1] On 1999 September 21, the Mw 7.6 Chi-Chi earthquake ruptured a segment of the Chelungpu Fault, a frontal thrust fault of the Western Foothills of Taiwan. The stress perturbation induced by the rupture triggered a transient deformation across the island, which was well recorded by a wide network of continuously operating GPS stations. The analysis of more than ten years of these data reveals...
