Media, Hazards, and Disasters

Media are a large influence on how the public perceives hazard, the probability of disaster, an unfolding crisis, and what should be done during an emergency.

So, this lecture will take up literature on media influence on perception, some reasons for their quirks, and consider some variations in different kinds of media. The upshot is pretty depressing, but understanding the media can help disaster planners and emergency managers anticipate and perhaps get ahead of the problems they pose and exploit the opportunities they present for public education

One theme in this literature is the sensationalism many media bring to hazards and disaster coverage, which can amplify public concern inappropriately or even hamper efforts to respond to a disaster. Firefighting crews are familiar with disaster "lookie-loos" (and media crews can logistically be almost as much trouble as the disaster sightseers their coverage attracts).

Some risk communication literature states that such comparisons might be a little unfair. The argument is that the media are not there faithfully to reproduce in print, radio, or images the exact probabilities or estimates approved by experts. Rather, they are to provide helpful information for people to evaluate and reduce their risk. Their rôle, then, might be or even should be less reportage than mass communication and public education.

There is a large body of literature, both professional and popular, that critiques media in general, but which may be specifically applicable to the hazards and disaster context. It identifies various filters that operate to bias media selection of newsworthy events from the chaos of everyday events.
