Not again! Another earthquake in Japan.

It's the disaster that will not end. Another 7.1 magnitude earthquake has hit Japan 100 miles north of Tokyo. An even more spooky detail, is the quake hit exactly as the people of Japan were taking a moment of silence to remember the 28,000 people dead and missing from the original earthquake and tsunami.

The latest aftershock caused buildings to sway in the capital Tokyo, shortly after the nation had observed a minute's silence to remember the 13,000 people killed in the March 11 disaster and the 15,000 who officially remain missing.

The US Geological Survey said the 7.1 onshore quake hit at 5:16 pm (0816 GMT) at a depth of just 13 kilometres (eight miles). Its epicentre was 81 kilometres south of Fukushima city, near the troubled nuclear plant.

Japan's meteorological agency warned that a one-metre (three foot) wave could hit Ibaraki prefecture, one of the areas pummelled by last month's massive tsunami, before cancelling the alert less than an hour later...

Workers battling to contain the crisis at the Fukushima-Daiichi nuclear plant were evacuated after the latest quake Monday, which briefly knocked out power to crippled reactors before electricity was restored.
