This research extracted and analyzed the data from " the most serious disaster information in the major disaster information social network " of 2009 Taiwan Morakot typhoon. It also discussed the relevance and trust of crowdsourcing disaster information through extracting, comparing and analyzing.

Thus, it can improve the efficiency on dealing with contingency or emergency through the diversification of information channels during calamity.
