They said it was the largest they had felt in the quake-prone city for some time. A spokesman for Tokyo Electric Power said the earthquake did not cause any additional damage at Fukushima Daiichi nuclear plant, the site of the worst nuclear accident in a generation where radioactive waste water has been leaking into the Pacific Ocean.
"We have confirmed that there was no immediate abnormality," according to data collected by monitoring equipment, a TEPCO spokesman said, adding that crews will patrol the crippled plant's vast campus to survey whether any physical damage has been caused. A series of leaks of radioactive water at the nuclear plant has left TEPCO on the back foot in recent months. Yesterday the Japanese government announced it was stepping in with USD 470 million of public money to build a wall of ice underneath the plant to prevent polluted water seeping out into the sea.
