About tsunami evacuation measures

Last update date December 8, 2020

In Yokohama-shi, we push forward various approaches based on lesson of the Great East Japan Earthquake of March 11, 2011 to ensure the security of citizen's from tsunami disaster that it will occur when in future, or it is not revealed.
It is difficult for tsunami to predict outbreak beforehand. When you confirm time that evacuation sites and evacuation always take and felt big shaking caused by earthquake and long shaking or when you knew information such as tsunami warnings, in spite of being appeal, "you evacuate to place that is earlier, and is higher", and please do evacuation around. And we hope that we do not leave safe place until tsunami warnings are canceled.

 In addition, based on District Public Prosecutor's Office where Cabinet Office "capital earthquake directly above the focus model review meeting" showed to in December, 2013, we made drawing which we put on top of one another about five earthquakes so that "the inundation area" and "flood depth" became greatest, and Kanagawa set as "tsunami inundation assumption" in March, 2015.
