TOKYO (AP) — A strong earthquake has shaken northeastern Japan.
The quake was centered in the same region devastated by a giant earthquake and tsunami 2-1/2 years ago, but there have been no immediate reports of damage or injuries.
Japan's Meteorological Agency gives the quake a preliminary magnitude of 6.0, but says there's no risk of a tsunami.
The quake shook a wide region, including the Fukushima (foo-koo-SHEE'-mah) prefecture. Tokyo Electric Power says no problems have been reported at the Fukushima Dai-ichi (foo-koo-SHEE'-mah dy-EE'-chee) nuclear plant and radiation monitors did not show any change.
Fukushima Dai-ichi plant went into multiple meltdowns after the March 2011 tsunami, and tons of water are being used daily to keep its reactors under control. Decommissioning is expected to take decades.
NHK TV reports some roads have been blocked off and trains temporarily halted for safety checks.
