"Did you feel that?" If you've ever uttered those words outside the bedroom then we've got news for you. A new earthquake warning device has been developed by Meir Gitlis which responds to the first, non-destructive wave offering tens of seconds of early warning. The device has already been fitted in the elevators of the Azrieli Towers in Israel where in the event of a quake, the system will halt the elevators at the nearest floor giving people a chance to seek cover. About the size of a shoe box (why always a shoebox?!) the device costs $170US.
