What Would An Earthquake-Proof City Look Like?
Japan sits in one of the most seismically active regions on the planet. Each year, the country experiences more than 100,000 earthquakes, according to the Seismology Society of Japan. After the catastrophic 1995 Great Hanshin earthquake — or Kobe earthquake is it more commonly known — the country mandated new engineering standards and sweeping retrofitting overhauls to prevent similar devastation in the future. Mori Tower is one of the tallest buildings in Tokyo and the tower was designed to be “a city to escape into rather than a city from which people run away.” To fulfil this ambitious goal, the Mori Tower features some of the most sophisticated motion-absorbing, earthquake-resistant building technology ever implemented. Like Taipei 101, Mori Tower uses damper engineering for seismic resistance. However, rather than implementing a massive tuned damper, Mori Tower uses 192 of fluid-filled shock absorbers. These semi-active dampers are filled with a thick oil, and as the tower begins to sway — as a result of tremor or high winds — this oil is sloshed in the opposite direction to counter and minimise this swaying.
