Earthquakes/Tsunamis Earthquakes/Tsunamis There are no safe places in Japan that do not experience earthquakes What if the Uemachi fault belt became active and a What if the Tokai, Tonankai, or Nankai Earthquake were to occur? Areas where there is expected to be severe damage through strong shaking and large tsunamis in the event of the Tokai, Tonankai and Earthquakes/Tsunamis Nankai Earthquakes have been designated in advance, and disaster prevention countermeasures are being strengthened. Great Hanshin Earthquake-level struck Suita City? "Earthquake Disaster Preventative Countermeasures Strengthening Area" and "Disaster Preventative Countermeasures Promotion Area" Estimated seismic intensity Estimated liquefaction Estimated physical damage The Tokai, Tonankai and Nankai Earthquakes are expected to cause severe damage in broad areas of western Japan. Given this, areas that have a particular need to promote earthquake disaster prevention measures have been designated. For the Tokai Earthquake the The entire Suita City would suffer an upper Liquefaction of sand would be developed About 60% of wooden buildings and 30% of "Earthquake Disaster Preventative Countermeasures Strengthening Area" (orange) has been established, and for the Tonankai and Nankai Fires 6-level on the Japanese earthquake scale. 7 on through the outburst and fluxion of sand in not other type buildings would be half or Earthquakes the "Disaster Preventative Countermeasures Promotion Area" (yellow) has been established, and e¤ orts toward earthquake the scale would also be registered in not only only the low-lying area on the Kanzaki River completely destroyed in the city. preparedness are being advanced.
