TOKYO - Japan's Nuclear Safety Agency said that pumping of water into three Japanese reactors to cool them was halted for about 50 minutes after the latest 7.1 aftershock on Monday, but that it was unlikely to have any impact on safety.
Senior agency official, Hidehiko Nishiyama, said: "It was stopped for about 50 minutes... safety issues are unlikely to have occurred from this."

The US Geological Survey reported that the very shallow quake was centered 14 miles (22 km)southwest of Iwaki, south of the stricken Fukushima nuclear plant.
Pacific Tsunami Center said the quake would had not triggered a
widespread tsunami that could reach the US and Canadian West coasts but
could cause a local one.
Japan said on Monday it may extend some
parts of an evacuation zone around its crippled nuclear plant if tests
show high radiation outside the area, imposed after an earthquake and
tsunami sparked the worst nuclear crisis since Chernobyl.
