Citizen communications in crisis

TLDR

Global crises have highlighted ICT’s potential for warning and response, yet command‑and‑control models struggle to accommodate the expanding data‑generating public participation that fosters improvised activities and temporary organizations needing alignment with formal responders. The study examines persistent citizen communications as a post‑impact response element, describing their spatial‑temporal patterns and how the resulting information pathways serve varied functions. We analyze persistent citizen communications by mapping their spatial and temporal arrangements and the information pathways they create for diverse post‑impact functions.

Abstract

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 post-impact 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-and-control models do not easily adapt to the expanding data-generating 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.
