A 7.1 magnitude earthquake has rocked the Fukushima nuclear power plant area in Japan. The NHK Television reports that the epicentre of the quake was 14 miles south of the nuclear plant near Iwaki in Fukushima Prefecture. A Tsunami warning has been issued all along the Pacific Ocean. Two reactors have been shut down. The aftershocks of the quake felt across Tokyo. The evacuation begins from Fukushima nuclear plant as major damage is expected. Earlier, Sirens wailed and people bowed their heads and wept along Japan's devastated northeast coast today as they marked a month since the tsunami that killed up to 25,000 people and unleashed a persistent nuclear crisis. With thousands of bodies yet to be found, a tsunami-flooded nuclear power plant still spewing radiation and more than 150,000 people living in shelters, there was little time for reflection on Japan's worst disaster since World War II.
