Seismic fault under nuclear reactor 'may be active'

A seismic fault running underneath a nuclear plant in western Japan is likely to be active, which could force the scrapping of one of its two reactors, according to a team of geologists.

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