Authority-to-Individuals Emergency Service ("Early Warning Service") Adhoc Meeting @ IETF#69

Introduction and Scope

During large-scale emergencies, public safety authorities need to reliably communicate with citizens in the affected areas, to provide warnings, indicate whether citizens should evacuate and how, and to dispel misinformation. Accurate information can reduce the impact of such emergencies.

Traditionally, emergency alerting has used church bells, sirens, loudspeakers, radio and television to warn citizens and to provide information. However, techniques such as sirens and bells provide limited information content; loud speakers cover only very small areas and are often hard to understand, even for those not hearing impaired or fluent in the local language. Radio and television offer larger information volume, but are hard to target geographically and do not work well to address the "walking wounded" or other pedestrians. Both are not suitable for warnings, as many of those needing the information will not be listening or watching at any given time, particularly during work/school and sleep hours.

This problem has recently been illustrated by the London underground bombing on July 7, 2006, as described in a government report. The UK authorities could only use broadcast media and could not, for example, easily announce to the "walking wounded" where to assemble.
