Tokyo: An earthquake shook Tokyo late Wednesday, but there were no reports of damage or casualties.The 5.4 magnitude jolt was felt in Tokyo and areas of eastern Japan at 11:47 am (1447 GMT), the US Geological Survey said.

The quake comes a week after the capital’s high-rise buildings were shaken by a 5.0 quake. Quakes of a similar scale also shock Tokyo on July 17 and 19.

There was no threat of a tsunami, the Japan Meteorological Agency said.
