TOKYO: An earthquake measuring 6.1 magnitude struck off northeastern Japan on Wednesday, the U.S. Geological Survey said. There was no immediate tsunami warning, or reports of damage or casualties.
A series of strong quakes struck the south of Japan late last week killing nearly 50 people. On Wednesday, survivors struggled with shortages of food and water.
The USGS said Wednesday`s quake was centred 104 km (about 60 miles) east southeast of Sendai, Honshu, near where a devastating quake and tsunami struck in March 2011. It was 51 km (30 miles) deep.
