Citizen Communications in Crisis: Anticipating a Future of ICT-Supported Public Participation

Recent world-wide crisis events have drawn new attention to the role information communication technology (ICT) can play in warning and response activities. Drawing on disaster social science, we consider a critical aspect of postimpact disaster response that does not yet receive much information science research attention. Public participation is an emerging, large-scale arena for computer-mediated interaction that has implications for both informal and formal response. With a focus on persistent citizen communications as one form of interaction in this arena, we describe their spatial and temporal arrangements, and how the emerging information pathways that result serve different post-impact functions. However, command-andcontrol models do not easily adapt to the expanding datagenerating and -seeking activities by the public. ICT in disaster contexts will give further rise to improvised activities and temporary organizations with which formal response organizations need to align.
