Japan’s century of efforts to tame earthquakes

By Etienne BALMER Takashi Hosoda was in a Tokyo skyscraper when the 9.0 magnitude quake struck on March 11, 2011, but the trained architect was “not particularly worried” as modern Japanese buildings are designed to protect their occupants. A century after Tokyo was destroyed in the Great Kanto Earthquake of 1923, the Japanese capital today bears no resemblance to the city levelled by that 7.9 tremor, which killed 105,000 people. The low-rise, largely wooden city […]
