Minor tsunami hits Japan after undersea quake

A wave of 20 centimetres (eight inches) was recorded in Kuji, eastern Iwate, at 9:07 am (0007 GMT), way below the possible one metre (3.3 feet) tsunami that the Japan Meteorological Agency (JMA) warned could hit.

The agency warned waters were still rising slightly in Kuji, although they were unlikely to swell too much further.

Waves of up to 10 centimetres were recorded along other parts of the coastline of Iwate prefecture.
There were no immediate reports of damage or casualties. Aerial footage showed no perceptible rise in sea level along the coast.

There was no visible change at the ports in the area, where broadcaster NHK has cameras permanently stationed.

The JMA said the 6.9 magnitude tremor struck at 8:06 am in the Pacific some 210 kilometres (130 miles) east of Miyako, at a depth of 10 kilometres.

An official told a Tokyo news conference that geologists regard the quake as an aftershock of the 2011 earthquake.

Local authorities in Iwate issued evacuation advisories to more than 19,000 people, NHK reported.
Large areas of the coastline covered by the advisory were ruined by the 2011 quake and tsunami, which left more than 18,000 people dead and triggered a nuclear accident in Fukushima.

The 9.0 undersea quake set off a massive tsunami that swamped cooling systems at the Fukushima Daiichi power plant, sparking the worst atomic accident in a generation.

The disaster, whose fourth anniversary falls on March 11, looms large in the Japanese psyche; the devastation and loss of life that it wrought reinforcing the country's natural cautiousness in the face of danger.

Japan is hit by around a fifth of the world's most powerful quakes every year due to its position at the conjunction of several tectonic plates.

Long experience has left it with strict building codes, such that powerful earthquakes that might raze cities in other countries tend to do little damage.

JMA Tuesday lifted a tsunami warning it issued after a 6.9-magnitude earthquake hit the northeastern region earlier in the day.
