PORTLAND - The massive earthquake that struck Japan in March of this year devastated that country. But it could have caused even more damage if Japan didn’t have a high-tech early warning system. Now, Northwest scientists are beginning to install a network of sensors that could send out alerts when a megaquake is on its way. As journalist Bill Lascher found, North America’s first earthquake alert system would be more sophisticated than the one in Japan.
