A tsunami alert was issued this afternoon (3.32pm GMT) after a 7.2-magnitude earthquake (revised from 7.4 magnitude) was recorded off Japan’s northeastern coast, shaking buildings in the country’s capital Tokyo for over a minute.

Tsunami waves of at least one metre in height were expected at 4pm GMT along the Japanese coastline, which was struck by a deadly Tsunami following a magnitude 9 earthquake last month. The tsunami warning was lifted shortly after 5pm.

The latest quake was measured at a depth of 49km, approximately 32km southeast of Ishinomaki and 37km east of Yamoto, according to the US Geological Survey. The quake hit 73 miles from Fukushima, where workers are still trying to contain the damage at a stricken nuclear plant, and 207 miles from Tokyo. Tokyo Electric Power Company says the plant was not adversely affected by today’s earthquake.

Hundreds of aftershocks have shaken the northeast region devastated by the March 11 earthquake, but few have been stronger than 7.0. There were two other earthquakes in the same region earlier today, measuring 4.5 and 4.6 on the Richter Scale.

Earlier today an earthquake measuring 6.5 on the Richter Scale struck near Veracruz, Mexico, though there were no immediate reports of injuries or damage.

The coldest winter you will ever experience is a summer in West Clare.

Largest Aftershock Upsets Quake Victims In Miyagi Pref., Vicinity

SENDAI (Kyodo)--The strongest aftershock since the devastating March 11 temblor jolted Miyagi Prefecture and its vicinity late Thursday night, upsetting residents already taking shelter at local facilities and resting in the dark at the time.

The 11:32 p.m. quake, with a preliminary magnitude of 7.4, measured upper 6 on the Japanese seismic intensity scale of 7 in northern and central parts of Miyagi Prefecture, the area hardest hit by last month's magnitude 9.0 quake.

Among nuclear power plants in the region, no abnormalities have so far been reported as a result of the quake at the crisis-hit Fukushima Daiichi or the nearby Fukushima Daini. Some external power supply, however, was disrupted at suspended plants and a spent fuel reprocessing plant in Miyagi and Aomori prefectures, causing them to use backup generators.

There were many emergency calls about injured people, fires and gas leakages, according to local police and fire departments, while the quake caused all expressways to be closed in Miyagi Prefecture and most train services to be suspended in the Tohoku region.

As of midnight Thursday, it had left some 3.64 million households without electricity in six prefectures, including those already without power.

''There are no TVs or radios available due to the blackout. All of us are worried,'' said Takeo Sato, 70, who was among residents staying at a sports arena in the tsunami-ravaged Miyagi town of Minamisanriku, all of whom dashed outside when the quake struck.

At a public gymnasium in the town of Onagawa, power went down shortly after the latest quake, and firefighters guided people outside.

''I was surprised but the jolt was not as big as the one before. I'm rather worried about the sea,'' said Fumie Yoshida, 37, a worker at a supermarket store in Sendai where bottles of soft drinks and other products were scattered by the tremors. A tsunami warning was issued at one point but lifted early Friday.

The Hayate shinkansen train was halted by the quake in a tunnel in Aomori Prefecture, with 15 passengers aboard, but all were rescued unhurt early Friday, East Japan Railway Co. said, adding it will suspend most train services in the Tohoku region for checks in the morning.

More than a dozen passengers of another halted train walked along the railroad to a nearby crossing in Fukushima Prefecture, JR East said.

At the Onagawa nuclear plant in Miyagi Prefecture, which has been suspended, two external power supply units among three have failed, and power supply was also disrupted at the No. 1 reactor, which had been suspended for maintenance, of the Higashidori nuclear power station in Aomori Prefecture, requiring the use of backup generators, Tohoku Electric Power Co. said.

In Rokkasho, Aomori Prefecture, external power supply was disrupted at the spent nuclear fuel reprocessing plant of Japan Nuclear Fuel Ltd.

While strong aftershocks have continued since the March 11 quake, it was the first to register upper 6 on the Japanese seismic intensity scale.
Why is cloud 9 so amazing ? What is wrong with cloud 8 ?
