Another earthquake hits Japan - tsunami warning issued.

      Japan issued a tsunami warning on Thursday after a magnitude-6.7 earthquake struck in the northeast of the country, rattling the areas hardest hit by the March 11 quake and tsunami disasters.  


But the meteorological agency lifted the warning about an hour after the latest jolt hit at 6:51 am (2151 GMT Wednesday) some 50 km off the east coast of Miyako, Iwate prefecture, at a depth of 20 km in the Pacific.
USGS also registered the quake at 6.7 in magnitude at a depth of 32 km.

Relatives of tsunami and earthquake victims offer silent prayers at a ceremony to mark 100 days since the deadly March 11 disaster at Ishinomaki in Miyagi prefecture on June 18, 2011.

The Japanese agency had warned that a 50 cm tsunami could be expected in the region, but no warning was issued to Fukushima at the centre of the nation's nuclear crisis.


Public broadcaster NHK reported there were no immediate reports of damage from the quake while no sizable high waves were seen.


Local authorities issued evacuation orders to some 8,000 households in Iwate, NHK said.


Shinkansen bullet train services were temporarily suspended, while there was no new damage to the Onagawa nuclear power plant in Miyagi, south of Iwate, which has been out of operation since the March 11 disaster, NHK added.


The northeast coast of Japan's main Honshu island was ravaged by a 9.0 magnitude quake and monster tsunami on March 11 which left some 23,000 people dead or missing.

The disasters also crippled the Fukushima Daiichi nuclear power plant, triggering the world's worst atomic accident since Chernobyl in 1986 and forcing hundreds of thousands of residents to leave their homes.
