This paper first illustrates Wenchuan Earthquake, and then introduces successful EEW cases such as Chile Earthquake and East Japan Earthquake and other unsuccessful EEW cases such as Haiti Earthquake and Yushu Earthquake. Furthermore, on the basis of principles of EEW, both outcome-based EEW and comprehensive outcome-based EEW are put forward and some EEW suggestions are given to China according to earthquake and its management in China.
