Most of the ~ 230,000 lives lost in the Indian Ocean Tsunami of December 2004 could have been saved if the
victims had had 5 - 15 minutes notice of the tsunami's arrival, provided that the local authorities had had some
evacuation plan in place, e.g. running up hill when a klaxon sounded, or retreating to low cost shelters
constructed to provide a vertical escape from inundation. Similar structures, equipped with supplies of drinking
water, food, blankets, etc., could save countless thousands of people from drowning in flood-prone locations
such as Bangladesh or the delta region of Burma, or dying in the aftermath of such events. Given sufficiently
rapid communications, a disaster nowcasting system could also order the closing of gas mains, or the
powering down of electricity networks, as well as the sounding of klaxons, only tens of seconds before an
earthquake wave strikes a major city such as Los Angeles. The central and critical requirement for mitigating
natural disasters is two-way communication. Imagine a globally accessible internet collecting event-triggered
messages from arrays of sensors (that detect inundation, for example) so they can be analyzed by centralized
computer systems in nearly real-time, which then send instructions to alarm systems and actuators in the
areas at risk. (Of course, local authorities would have to be involved in planning the local responses to alarms,
in constructing rescue facilities, and in educating their populations accordingly). Only a constellation of
satellites could provide a communications system with global accessibility and the required robustness. Such
an infrastructure would allow the international community to exploit the many common elements in the
detection, assessment and response to unfolding disasters. I shall describe some of the elements of such a
system, for which I propose the working name CELERITY.
