Japan struck by magnitude 6.8 earthquake It is 10 months since an earthquake and tsunami hit Japan causing extensive damage and destruction at the Fukushima nuclear power. Photograph: AP A strong earthquake has jolted eastern and northeastern Japan, but there are no immediate reports of injuries or damages and no tsunami warning has been issued. The earthquake - of magnitude of 6.8 - measured 4 in central Tokyo, Fukushima and their surrounding areas on the Japanese intensity scale, which measures ground motion, according to Japan Meteorological Agency. A spokesman for Tokyo Electric Power said there were no reports of any abnormalities at the tsunami-crippled Fukushima Daiichi nuclear plan following the quake. Some high-speed train services in northern Japan were suspended after the earthquake, but soon resumed operations, Kyodo news reported. The magnitude 6.8 earthquake, at a depth of nearly 217 miles, was recorded south-southwest of Hachijo-jima off Japan's southeastern Izu islands on Sunday at 5.27am GMT, the US Geological Survey reported. The Hawaii-based US Pacific Tsunami Warning Centre has not issued a tsunami. Earthquakes are common in Japan, one of the world's most seismically active areas. The country accounts for about 20% of the world's earthquakes of magnitude 6 or greater. On 11 March 2011, the northeast coast was struck by a magnitude 9 earthquake, the strongest quake in Japan on record, and a massive tsunami, which triggered the world's worst nuclear crisis in 25 years since Chernobyl. The disaster left up to 23,000 dead or missing.
