tsunami evacuation measures

Based on the lessons learned from the Great East Japan Earthquake of March 11, 2011, Yokohama City has been promoting various initiatives to ensure the safety of citizens from the tsunami disaster, which will not occur at any time.
tsunami is difficult to predict the outbreak in advance. Always check the evacuation sites and the time required for evacuation, and if you feel a large or long shaking due to an earthquake, or if you know information such as a tsunami warning, call for evacuation around you. Evacuate to a higher place. " Then, please do not leave a safe place until the tsunami warning is canceled.

　Of the tsunami envisioned by Kanagawa Prefecture in March 2012, Yokohama City is implementing tsunami measures as a model of the tsunami based on the Keicho era earthquake.
　In addition, based on the Public Prosecutors Office presented by the Cabinet Office's "Earthquake Model Study Group" in December 2013, Kanagawa Prefecture superimposed the five earthquakes so that the "flood area" and "inundation depth" were the maximum. We made a drawing and set it as "tsunami inundation assumption".
　It will be posted as a reference.
