Nuclear Test Gauges Beat CNN, Aid Radiation Watch in Japan

Devices used to monitor a potential ban on atomic-weapons testing are helping warn of possible tsunamis from aftershocks in Japan and may aid in tracking radiation leaks from the country’s damaged nuclear plants.

The Comprehensive Test Ban Treaty Organization’s preparatory commission sent data on March 11 to seven tsunami warning centers in the Asia-Pacific region, including in Japan and the U.S., officials said in a telephone interview yesterday from Vienna.
