- Abstract
- This brief note provides a summary of pertinent information from two previous reports on young faulting in Taiwan (Bonilla, 1975, 1977). In addition to listing historic surface faulting, this note gives information about several Quaternary faults in the epicentral region that could have been involved in the 1999 Chi-Chi earthquake, and the relation of one of them (the Chelungpu thrust fault) to several other faults, including those that had surface ruptures in the 1906-1946 period. The two reports (Bonilla, 1975, 1977) provide data and interpretations from still earlier reports, and can serve as background for post-earthquake investigations. The two reports are being processed for inclusion in the International Association of Seismology and Physics on the Earth's Interior (IASPEI) 'International Handbook of Earthquake and Engineering Seismology,' and are expected to be available on the Internet in the near future. In the meantime, this note may be of use to those investigating primary and secondary faulting in the September 21, 1999, Chi-Chi Taiwan earthquake.
