This study objectively investigates the potential of rainfall that could trigger the earthquake from the earthquake number (ML≧6.0) and rainfall information during the time period from January 1995 to August 2012. (Lin 2013) reported the similar work that the typhoons could trigger small earthquakes easily especially after Chi-Chi earthquake during January 1995 to July 2012. The earthquakes are likely to have significant positive relationship with rainfall after the Chi-Chi earthquake with Chi-Square test. The result revealed a significant difference between the correlations of daily-accumulated rainfall values and earthquake activities both before and after the Chi-Chi earthquake. The significant difference has been discussed regarding changes of crustal conditions after the Chi-Chi earthquake.
