The 1999 Chi Chi, Taiwan, earthquake provides case histories of ground failure and non-ground failure that are valuable to the ongoing development of liquefaction susceptibility and triggering models because the data occupy sparsely populated parameter spaces (i.e., high cyclic stress ratio and high fines content with, low to moderate soil plasticity), In this paper, we synthesize results from several large site investigation programs conducted in Nantou and Wufeng, Taiwan, and compare the data to susceptibility and triggering models. With regard to liquefaction susceptibility, we find components of the well-known Chinese criteria associated with liquid limit (LL) and water content/LL to be reasonably well validated by the Taiwan data, but clay fraction criteria and CPT-based criteria to not be effective. Triggering models are generally validated for ground failure sites, but the data raise important questions regarding non-ground failure sites whose performance is not well predicted.
