End of the World - Be prepared

On Saturday 14 November 1800-2200 UTC on or near the emergency centre of activity frequencies on the 80, 40, 20, 17 and 15 metre bands more than 200 stations representing IARU member societies and Emergency Communications Groups in 45 countries around the world took part in the latest Global Simulated Emergency Test. GlobalSET provides an opportunity to demonstrate the provision of communications across national borders, test the emergency centre of activity frequencies, create practices for international emergency communications and the relaying of messages.

I was unable to listen or take part in what was going on as I was working but I am sure plenty will be written about the success or otherwise of the event. What I would like to know is what exactly might constitute a global emergency? An asteroid strike, a large volcanic event, an alien invasion, the Cern Large Hadron Collider sucking Switzerland into a black hole or what? I just hope I am not around if any of these things happen, but I am keeping my batteries charged in case, maybe you should do the same.
