Phenomena associated with the 1999 Chi-Chi Earthquake in Taiwan, possible precursors and after effects

Abstract

The authors conducted interviews about the Chi-Chi earthquake during a geological field investigation in order to build records about its possible precursors and after effects for future preservation. The precursors reported include aberrant animal behavior and non-animal related activity. Phenomena observed during and after the earthquake may be related to seismic energy released and displacement of the crustal structure. We, therefore, suggest establishing a warning system based on a watch network under proper government jurisdiction. Such a warning system would be beneficial in the prevention of future prevent casualties.
