Exploring extreme events on social media: A comparison of user reposting/retweeting behaviors on Twitter and Weibo

Although recent research suggests that Twitter and other forms of micro-blogging are becoming increasingly relied upon by both the public and response agencies dealing with crises and disasters, little is known about how these dynamics may play out in a non-Western context. The current study examines the use of the Chinese Weibo service during a 2013 smog emergency, and compares user generated content to that found in earlier data concerning a weather event in North America. The results indicate that by way of comparison, the Weibo sample contained proportionately similar degrees of informative and affective content, but that users were less likely to use humor and showed no increase in affective outpouring as the crisis developed. Results are discussed in terms of implications for those designing social media campaigns for informing and motivating those affected by large-scale weather-related crises. A cross-cultural comparison of Twitter retweets and Weibo reposts for a crisis event was conducted.Differences emerged in type and rate of retweet/repost.Differences in informative and emotional content were found.Application of the results are discussed.
