Japan's Oi Nuclear Plant, which houses the country's only still-running reactors, sits atop an inactive fault.WIKIMEDIA, NATIONAL AND IMAGE INFORMATION (COLOR AERIAL PHOTOGRAPHS), MINISTRY OF LAND, INFRASTRUCTURE, TRANSPORT AND TOURISMAfter a devastating earthquake and tsunami hit Japan in March 2011, damaging and releasing radiation from the Fukushima Daiichi power plant, about 50 of the country’s nuclear reactors have been waiting for the green light to power back up. Though plans to reboot Japan’s slumbering nuclear reactors have been progressing since the disaster, a panel of geophysicists working for the Nuclear Regulation Authority (NRA) is now warning that some of the plants that house them are still at risk of damage by earthquakes.

Initial reports issued by the NRA panel last month indicate that at least some of the reactors sit above active seismic faults that put the facilities in danger should earthquakes strike again. For example, the team of geophysicists has suggested that an active fault, defined as a region of the earth’s crust that has shifted causing an earthquake in the past 120,000 years, may lie below Japan’s Tsuruga nuclear plant, which was set to power back up soon. The NRA panel is investigating the seismic situation at Tsuruga, as well as potentially active faults near four other plants set to come back online soon.

But some in Japan, including seismologists and a nuclear industry eager to restore the country’s nuclear energy capacity, are questioning the ...
