Damage assumption of Yokohama-shi

Last update date February 14, 2019

About earthquake damage assumption of Yokohama-shi

What we assume beforehand what kind of influence there is by major earthquake is important in thinking about reduce disaster damage action. Therefore is it lesson of the Great East Japan Earthquake?
jifuruihigaiso which repeats discussions based on ra, new scientific knowledge and earthquake-related data which accumulated with person of learning and public utilities company, and is new
We devised constant o. (as for the person who wants to look at in detail Yokohama-shi earthquake damage assumption working papers (October, 2012))

Earthquake that it was said that it was targeted for assumption

We did four earthquakes for earthquake damage assumption if targeted for assumption.

●Genroku era type Kanto earthquake
Energy of about 2 times of Taisho type Kanto earthquake which brought the Great Kanto Earthquake
It is 8.1-magnitude assumption earthquake to give off rugi. The city
Maximum seismic intensity is assumed to be 7 of this.

●Nankai Trough massive earthquake
ma which we take up as thing bringing massive tsunami in Cabinet Office

●Earthquake in northern Tokyo Bay
Mug that it is said that influence in metropolitan area including Motoichi is extremely big
