Saving Lives by Detecting Tsunamis Sooner
Tsunamis give little or no warning to their victims to escape the deadly waves. Tsunami detection and warning systems that can save lives by giving people a chance to get out of disaster's path. LewHill Testing Technologies, an incubator company located at the NRC in St. John's, Newfoundland, has developed a better system for detecting tsunamis – one that could reduce the scale of future tragedies by saving thousands of lives.
