Seconds Before the Big One: Progress in Earthquake Alarms
Earthquake detection systems can sound the alarm in the moments before a big tremor strikes—time enough to save lives
Such a system would require only a modest investment compared with the potential dangers of a major earthquake—100 new seismic stations and upgrades to existing infrastructure, at a total cost of $80 million. In five years the system could be up and running. In six we could be very thankful that it is.
