Scientists: Fault under Japan nuke may be active

The five-member panel commissioned by the Nuclear Regulation Authority announced Monday that the structure underneath the Tsuruga plant showed signs of seismic movement around 100,000 years ago, recent enough to still be active.

Japanese guidelines prohibit nuclear facilities above active faults. Tsuruga's No. 2 reactor sits directly above the fault and would have to be scrapped if the panel's conclusion is officially accepted.
