TOKYO (Reuters) - A earthquake with a preliminary magnitude of 6.7 jolted eastern Japan early on Thursday, and was felt over a wide area, including in Tokyo, Japan's meteorological agency said. The quake, at 1:45 a.m. (12:45 p.m. EDT, Wednesday), was centered in the Pacific Ocean east of Tokyo. There were no immediate reports of injuries or damage after the quake, which measured 5 on the Japanese scale of 7 in some parts northeast of Tokyo, NHK said. No tsunami damage was expected from the quake but there may be slight sea level changes, the agency said on its website.

A SERIES of strong earthquakes including one with a magnitude of 6.7 hit the Tokyo area early today, cutting off power to more than 2000 homes and causing light injuries, officials and reports said. Japan's meteorological agency warned that more moderate aftershocks could strike, although there were no fears of a tsunami. The strongest earthquake hit at 1.45am (2.45am AEST) in the Pacific Ocean off Ibaraki prefecture, some 100km northeast of Tokyo.
Public broadcaster NHK said that two people were lightly injured, including an 18-year-old boy who was hit by his falling stereo speaker. Power was cut off to 2100 households, the network said, quoting local officials. The impact was strongest in Ibaraki and adjacent Tochigi prefecture where the earthquake measured lower-five on the seven-point Japanese scale - strong enough to crack holes in weak buildings. "We felt a strong jolt, but there are no reports as of now of any major damage," an Ibaraki police spokesman said. Highway operators said they had lowered the speed limit as a precaution, although they had not detected any damage to the roads from the quake, which struck at a depth of 40km.
The earthquake followed a series of tremors off the Pacific coast early today, including one measuring 6.3 on the Richter scale. The quakes rattled buildings in the heart of Tokyo, where Chinese President Hu Jintao was staying on a rare visit to Japan. Japan experiences 20 per cent of the world's major earthquakes and has developed an infrastructure meant to withstand violent tremors.
A 6.8-magnitude earthquake rocked central Japan in July last year, killing 11 people and shutting down the world's largest nuclear power plant. Tokyo Electric Power Co said its nuclear power plants were not damaged by the latest earthquakes, according to NHK. Japan lies at the crossing of four tectonic plates and is constantly bracing for the dreaded "Big One" feared to inflict major damage. A 7.3-magnitude earthquake in Tokyo could kill 4700 people, damage 440,000 buildings and leave thousands of others trapped in elevators, according to a study published by the government in 2006. The last major tremor in Tokyo was the Great Kanto Earthquake of 1923 which left 142,807 people dead or unaccounted for. Japan marks the September 1 anniversary each year with nationwide disaster preparation drills.

Japan is vanochtend vroeg opgeschrikt door een reeks aardbevingen. De zwaarste had een kracht van 6,7 op de schaal van Richter. Het epicentrum lag op 100 kilometer ten noordoosten van Tokio. Volgens de eerste officiële berichten zitten meer dan 2.000 gezinnen zonder stroom. Voorlopig is er enkel melding van lichtgewonden. Het Japans meteorologisch instituut waarschuwt alvast dat er nog lichtere naschokken kunnen volgen. Een tsunami wordt niet meteen verwacht.
Twintig procent van 's werelds krachtigste aardbevingen komen voor in Japan. Vorig jaar in juli werd het land nog getroffen door een aardbeving van 6,8 op de schaal van Richter. Elf mensen kwamen toen om het leven en de grootste kerncentrale ter wereld moest gesloten worden.
'The Big One'
Omdat Japan boven de kruising ligt van vier tectonische platen komen aardbevingen er vaker voor dan elders. Het land bereidt zich dan ook voor op de 'Big One', een aardbeving die een ongeziene ravage zou aanrichten. Volgens een recente studie van de overheid kan een aardbeving van 7,3 op de schaal van Richter in Tokio 4.700 levens eisen, 440.000 gebouwen beschadigen en duizenden mensen in liften vast houden.
De laatste zware aardbeving in Tokio was de Grote Kanto Aardbeving in 1923. Toen kwamen 142.807 mensen om het leven. Elk jaar op 1 september wordt die ramp herdacht met evactuatieoefeningen over het hele land.
