Japan issues tsunami advisory after 6.9 earthquake

JAPAN has issued a tsunami advisory following a 6.9-magnitude earthquake in northern Japan.

The nation's meteorological agency said a tsunami of up to one metre was forecast to hit the coast of Iwate at around 8.30am (1030 AEDT).

The agency urged residents to take particularly care if the tsunami arrives at high tide, boosting the height of the waves.

Coastal towns in Iwate prefecture were advised to evacuate. There are more than 10,000 people in the area.

People were warned not to approach the coast until the tsunami advisory had cleared.

Large areas of the coastline covered by the latest warning were damaged by the 2011 quake and tsunami that killed more than 18,000 people.

The disaster triggered a nuclear accident in Fukushima.

There is no threat to the wider Asia-Pacific area or Australia.

The earthquake news comes after Queensland was hit by a 5.1 magnitude earthquake on Monday.

Australian experts say we can expect to see more of them.

Senior seismologist Dr Jonathan Bathgate from Geoscience Australia said the central Queensland area, and Gladstone, was the most active area in Queensland for earthquakes because it was close to a local fault line.

"Australia is moving 7cm north per year," Dr Bathgate said.

"Stresses build up in the ground and when they exceed the strength of the rocks that stress is released causing movement along the fault lines."

The quake originated between 20km-30km north east of Eidsvold, but was felt within a 187km radius, including Gladstone, about 2am yesterday.

The main shock had a magnitude of 5.1 and an aftershock of 2.9.
