This paper presents a case study of microblogging during the Norway attacks on 22 July, 2011, during which a single person first detonated a bomb in Oslo, killing eight people, and then shot 69 young people on the island of Utøya. It proposes a novel way of conceptualizing the public contribution to mobilization of resources through microblogging, particularly tweeting, as a form of ‘peripheral response’. By examining the distributed efforts of responding to the crisis in relation to emergent forms of agile and dialogic emergency response, the paper also revisits the concept of situation awareness and reflects upon the dynamic and constantly changing environment that social media and crises inhabit together.
