Abstract(in English) In this paper, we analyzed the 400 millions of Tweet data which posted around the Great East Japan Earthquake to find how the twitter used and how the Twitter was influenced by the disaster. We modeled the time series data of Retweet by Gaussian Mixture Model. By analyzing the model, we found that the peak times of the retweets are become shorter, and there are few long range retweets after the disaster. As a result, we can say that the role of the Twitter was changed from communication tools to information sharing tools since the Great East Japan Earthquake were occurred.
