| Abstract: | AbstractThis study was carried out to investigate the role of rainfall in triggering ordinary earthquakes that occurred before and after the major Chi-Chi earthquake (7.2 ML) in central Taiwan on 21 September 1999. To test a possible mechanism, earthquake activities from January 1995 to July 2012 were examined. The Chi-square (χ2) test revealed a significant difference between the correlations of monthly accumulated rainfall values and earthquake activities before and after the Chi-Chi earthquake. This result is discussed in terms of changes in crustal conditions after the Chi-Chi earthquake. Two ordinary earthquakes that may have been associated with heavy rainfall after the Chi-Chi earthquake are identified. Editor D. Koutsoyiannis; Associate editor A.
