A magnitude 7.0 earthquake has struck off Japan's south-western coast, triggering a small tsunami.

The Japan Meteorological Agency (JMA) said a 30cm (1ft) tsunami was registered on the southern Nakanoshima island, part of Kagoshima prefecture.

There were no immediate reports of damage or injuries.

A tsunami warning issued for Kagoshima and Satsunan islands was later lifted. The quake happened at a depth of about 10km (six miles).

The US Geological Survey said it was some 159km south-west of the town of Makurazaki.

In 2011, a massive earthquake caused a tsunami that left more than 18,000 people dead or missing in north-eastern Japan.

Some 230,000 people have yet to return to their home towns since the disaster.
