Yes they claimed it was designed to handle a quake no bigger then 7.5, this one is now officially at 9.0. Sadly the death toll will be high, the economic impacts (lost of productivity and food source) will be known in a few weeks. BTW a volcano in the south also erupted. People in Japan are prepared for the big one, but many hope they will never see one, the big one known as Great Kantō earthquake is the one they fear the most. The current one is now known as the Honshu earthquake which is to the north of Tokyo. Kantō quake will be to the south and very close to Tokyo. Pray we never get to witness the Kantō earthquake nor the San Fransisco quake.
