Our research focuses on the Twitter activity related to the heavy floods that occurred in Sardinia in November 2013, with special regard to the hashtag #allertameteoSAR. As institutional social media communication was generally lacking, the hashtag witnessed a user-driven shift: at the beginning it was used as a general-purpose hashtag; in the following days, some active Twitter users succeeded in transforming it into the “(un)official” hashtag for disaster recovery-related conversations. We analyze the whole dataset of the tweets with hashtag #allertameteoSAR that have been produced during the first week of the Sardinian floods (around 70.000 tweets have been extracted through GNIP “Historical Power Track”).

Abstract
Our research focuses on the Twitter activity related to the heavy floods that occurred in Sardinia in November 2013, with special regard to the hashtag #allertameteoSAR. As institutional social media communication was generally lacking, the hashtag witnessed a user-driven shift: at the beginning it was used as a general-purpose hashtag; in the following days, some active Twitter users succeeded in transforming it into the “(un)official” hashtag for disaster recovery-related conversations. We analyze the whole dataset of the tweets with hashtag #allertameteoSAR that have been produced during the first week of the Sardinian floods (around 70.000 tweets have been extracted through GNIP “Historical Power Track”).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
