This book is about how different communicators - whether crisis managers, first responders, journalists, or private citizens and disaster victims - have used social media to communicate about risks and crises. It is also about how these very different actors can play a crucial role in mitigating or preventing crises. How can they use social media to strengthen their own and the public's awareness and understanding of crises when they unfold? How can they use social media to promote resilience during crises and the ability to deal with the after-effects?
Chapters address such questions by presenting new research-based knowledge on social media use during different crises: the terrorist attacks in Norway on 22 July 2011; the central European floods in Austria in 2013; and the West African Ebola-outbreak in 2014. The collection also presents research on the development of a tool for gathering social media information, based on a user-centered design.
