10. Twitter and the Queensland Floods First lessons: #qldfloods as coordinating tool – one central hashtag Go where the users are – and help establish hashtag Plus inventive additions – e.g. @QPSmedia #Mythbuster tweets Most activity by individuals – but key official accounts cut through Enable easy retweeting and sharing of messages Respond and engage Mainstream media are important in social media environments, too Twitter as an amplifier of key messages Twitter vs. Facebook – which works when?

18. Twitter and the Christchurch Earthquake Towards better strategies for social media in disasters: February 2011 earthquake building on lessons learnt in September 2010 #eqnz and key Twitter accounts already established Several key accounts sharing the load and dividing responsibilities More experienced use of Twitter by residents and authorities Clear shift in attention after the immediate rescue phase: Marked differences in list of most @replied/retweeted accounts Some tracking of current problems / issues / fears may be possible Decline in overall tweet volume / diversification of #hashtags?

19. Background: Researching Twitter #hashtag studies: Selected #hashtags captured from the Twitter API using yourTwapperkeeper Data processing using custom-made tools – keyword and network analysis Statistic and network visualisations – including dynamic visualisations Broader research: #hashtags are limited – much additional activity outside #hashtags How do #hashtags emerge, how do users encounter and choose them? How much does Twitter use during crises differ from everyday usage? Mapping Online Publics: ARC Discovery project, 2010-12: Assoc.
