6.8-magnitude earthquake hits Pacific near Fukushima plant

JAPAN'S east coast has been hit by a minor tsunami after a strong 6.8-magnitude earthquake struck in the Pacific, prompting advisories for regions including around the crippled Fukushima nuclear plant.

A tsunami of 20 centimetres was observed at 5:12am (local time) in the city of Ishinomaki in the Miyagi prefecture.

The Japan Meteorological Agency had issued a tsunami advisory for Miyagi, as well as the neighbouring Fukushima and Iwate prefectures, warning a local tsunami of up to 1 metre could impact their Pacific coastlines after the quake.

US geologists placed the quake's epicentre at a depth of 13 kilometres.

Large areas of the coastline covered by the advisory are still recovering from the 2011 quake and tsunami disaster that killed more than 18,000 people and triggered a meltdown at the Fukushima Daiichi nuclear plant.
