Tsunami waves has hit the northern Japan on Tuesday. It was recorded at up to 4.5 ft high at Sendai, with smaller waves hitting elsewhere along the coast.
According to media reports, the Japan Meteorological Agency said the quake was an aftershock to the 2011 earthquake, the largest since that quake’s immediate aftershocks.
The JMA had said that the earthquake, which was felt in Tokyo, had a magnitude of 7.4 and was centred off the coast of Fukushima prefecture at a depth of about 10 km (6 miles).
It had also warned that another large quake could be expected within the next few days, and people in the region have been advised to “remain cautious” for the next week.
No loss of life has been reported but thousands of residents flee for higher grounds after the strong quake.
Tsunami warnings were also issued for the Fukushima and Miyagi prefectures, with waves at Sendai port recorded at 1.4m high. The warnings have since been downgraded, before being cancelled, although residents are still advised to avoid the shore.
