• Change the datum



Japanese to English

There are some ways to writing from Japanese municipality name to English one.

Romaji : We have many styles of writing. Omiya or Ohmiya or Oomiya

Kodushima or Kodsushima or Koudushima ……

Category of Municipality Kyoto city or Kyoto-shi

Koshiji town or Koshiji-machi

Takizawa village or Takizawa-mura

In the case of old earthquake, we know only Kanji (Chinese character). We have several ways of pronounce each Kanji, so we can’t determine one way to pronounce.

2011 Tohoku EQ

investigation’s data

by web site (Advanced

registration for researchers is

required)

Inundation area,

Inundation depth,

damage on

buildings,

evacuation way,

Infrastructure

damages, Lifeline

damages….



Characteristics of Japanese Study

Almost Japanese studies’ data source is each municipality government’s complete survey for relief act. Therefore buildings are not categorize by their structure (Only Residence or Non-residence).

There are some studies base on other point of view (building age, structure, roof type, wall type…..). But in many cases, they are not compete survey.

Boundary data by each EQ is not provided. So we have to fix it.
