Magnitude-7.3 quake hits Japan, tsunami warning issued (UPDATE)
Adds tsunami warning lifted, magnitude revised to 7.3 (first version posted at 06:54)
A magnitude-7.3 earthquake struck north-eastern Japan Sunday morning, the Meteorological Agency said, dpa reported.
No casualties or damage were reported. The quake prompted the agency to issue a tsunami warning on the coast of the prefectures of Iwate, Miyagi and Fukushima, but it was lifted at 11:45 am (0245 GMT).
The agency also revised the quake's magnitude to 7.3 from an initial reporting of 7.1.
The quake occurred at 9:57 am (0057 GMT) with an epicentre off Ojika Peninsula at a depth of 10 kilometres, the agency said.
The same region was struck by a magnitude-9.0 quake and tsunami on March 11 that caused the ongoing nuclear disaster at the Fukushima Daiichi power plant.
