Japan earthquake

As you know japan is in crisis, as it has to deal with whole towns being swept away and the Fukoshima power plant. In some cases it was less severe as in Tokyo buildings just swayed thanks to rubber piles beneath the buildings and the fact that some are nailed together so that earthquakes don't make them collapse. However on the other end of the scale whole towns have been reduced to rubble due to the tsunami and not the earthquake. Fukoshima however is rumoured to be wrapped in concrete wall to stop radiation leaking from the reactors. Like when the first nuclear fallout some people may not be able to return to their homes because radiation lasts along time.
