The document discusses the 2011 Tōhoku earthquake and tsunami in Japan and how coverage of the crisis on Twitter affected emergency preparedness advocacy worldwide. It analyzed over 1.4 million tweets between March 1st and April 1st, finding that almost 75% positively reflected Japan's preparedness efforts or advocated for preparedness. The Twitter coverage raised questions about individual and community preparedness levels and generated new discussions around preparedness for vulnerable groups. However, the analysis was limited by only focusing on tweets in that time period and not considering language limitations.
