A Major Earthquake in the Strong Crust: the 1999 Chi-chi Earthquake
The 1999 Chi-Chi earthquake (MW=7.6; ML=7.3) ruptured in an area considered unusual in that, historically, large earthquakes have been unheard of and the background seismicity are low. A detailed investigation of the crustal characteristics based on seismicity, subsurface structures and GPS surveys shows that crustal strength in the low-seismicity block was most likely stronger than in the surr...
متن کاملSlip history and dynamic implications of the 1999 Chi-Chi, Taiwan, earthquake
[1] We investigate the rupture process of the 1999 Chi-Chi, Taiwan, earthquake using extensive near-source observations, including three-component velocity waveforms at 36 strong motion stations and 119 GPS measurements. A three-plane fault geometry derived from our previous inversion using only static data [Ji et al., 2001] is applied. The slip amplitude, rake angle, rupture initiation time, a...
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 کاملDamage to Critical Facilities Following the 921 Chi-Chi,Taiwan Earthquake (1999-2000)
As part of research collaboration between MCEER and the National Center for Research in Earthquake Engineering (NCREE) in Taiwan, a team of MCEER/NCREE researchers undertook a reconnaissance mission shortly after the 921 Chi-Chi earthquake occurred in Taiwan at 1:47 a.m. on September 21, 1999. A major objective of this mission was to assess earthquake-induced damage, to document lessons learned...
متن کاملObservations of changes in waveform character induced by the 1999 Mw7.6 Chi-Chi earthquake
[1] We observe changes in the waveforms of repeating earthquakes in eastern Taiwan following the 1999 Mw7.6 Chi-Chi earthquake, while their recurrence intervals appear to be unaffected. There is a clear reduction in waveform similarity and velocity changes indicated by delayed phases at the time of the Chi-Chi event. These changes are limited to stations in and paths that cross the 70 × 100 km ...
