Description:Buildings shake as a 7.3 magnitude earthquake rocks the Japanese city of Sendai. The quake triggered a one-metre tsunami in an area devastated by last year's Fukushima disaster, but there were no reports of deaths or serious damage. None can forget the March 2011 earthquake and tsunami which killed nearly 20,000 people and triggered the world's worst nuclear crisis in 25 years. But earthquakes are normal in Japan and these diners appeared unperturbed.(0:43)
