Tokyo/Nagpur: Tokyo was struck by a third quake in four days on today, but there were no reports of damage or casualties.
The 5.0 magnitude jolt struck Tokyo and areas of eastern Japan at 7:25 am (3:55 am IST), the US Geological Survey said.
The quake’s epicentre was east of the capital in Ibaraki at a depth of about 44 kilometres, the USGS said.
There was no threat of a tsunami. It was the third to shake the capital’s high-rise buildings this week, after a 4.8 magnitude quake yesterday and a 5.0 on Sunday.
Japan sits at the junction of four tectonic plates and experiences a number of relatively violent quakes every year, but rigid building codes and strict enforcement mean even powerful tremors frequently do little damage.
