Japan: Tokyo 'has 70% chance of powerful earthquake within four years'

Although newer buildings in Tokyo are built to withstand powerful earthquakes, a large quake in the city has the potential to cause widespread damage, reports Justin McCurry for the Guardian. Chances of a magnitude-7 earthquake striking Tokyo had increased since 11 March, asserts Shinichi Sakai, an associate professor at the earthquake research institute. "The government, individuals and corporations should make preparations for that now," he said.
