Abstract

A 200 km-wide thermal anomaly was recorded by thermal infrared satellite data in a heavily faulted region of the South China Sea, at the time of the 1999 Chi-Chi earthquake in Taiwan. Subsurface data, including vitrinite reflectance data, indicate anomalously hot fluid flow in porous aquifers in the geological record for the same region. These observations link a seismic thermal anomaly to the long-term expulsion of hot fluid from a deep, overpressured aquifer. (C) 2006 Elsevier B.V. All rights reserved.
