Horizontal coseismic deformation of the 1999 Chi-Chi earthquake measured from SPOT satellite images: Implications for the seismic cycle along the western foothills of central Taiwan
[1] The 1999 Chi-Chi earthquake, Mw = 7.6, broke a major thrust fault along the western foothills of the Central Range of Taiwan. We have measured the horizontal coseismic displacement field by correlating optical satellite images acquired before and after the earthquake. These data reveal the fault trace and a clockwise rotation of surface displacements toward the north with much larger displa...
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...
متن کاملCoseismic release of water from mountains: Evidence from the 1999 (Mw 5 7.5) Chi-Chi, Taiwan, earthquake
Earthquake-induced increases in streamflow, producing ;0.7 km3 of total excess water, were documented after the 1999 (Mw 5 7.5) Chi-Chi earthquake in central Taiwan. Analysis of stream gauge data and well records suggests that the excess water originated in the mountains. We propose that the extensive high-angle fractures formed during the earthquake allow rapid release of water from mountains ...
متن کاملCoseismic ionospheric disturbances triggered by the Chi‐Chi earthquake
[1] At 17:47 UT on 20 September 1999, a large earthquake of magnitude Mw 7.6 struck the central Taiwan near a small town of Chi‐Chi. The ground‐based receivers of the global positioning system (GPS) in the Taiwan area detected coseismic ionospheric disturbances (CIDs) in the total electron content (TEC) triggered by the Chi‐Chi earthquake. When the CIDs travel away from the origin on the Earth ...
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...
