Damage 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 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 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...
