Guideline for Development and Utilization of Tsunami Disaster Management Map
Reduction of tsunami disasters in a region and a community is attained with a comprehensive approach involving
the integration of land use planning, construction of coastal protection facilities and measures for increasing thepeople's self-protecting capability against disasters. Tsunami disaster management maps indicate tsunami hazards
and vulnerability in the region and community as well as countermeasures against the tsunamis. A tsunami disastermanagement map is a good tool to investigate and establish comprehensive disaster mitigation system, since it
provides necessary graphical information to manage tsunami disasters and minimize damage in the region as well
as regional tsunami hazards and vulnerability.
This guideline aims to assist developing countries, in particular countries affected by the 2004 Indian Ocean
Tsunami and of ASEAN, in developing and utilizing the tsunami disaster management maps. It clarifies the basic
concepts such as the purpose, role, method, and utilization of such maps.

Features- To describe the contents for those who have less knowledge of tsunamis and tsunami numerical simulation in aneasy to understand manner- To list actual examples of the utilization of disaster prevention maps in order to make it easy to understand for
those in charge of administration in developing countries- To prepare the storm surge hazard map and to analyze the effects of sea level rise due to global warming

What is a Tsunami Disaster Management Map?
Tsunami disaster management map contains two typesof information to mitigate the tsunami disasters:- Information of tsunami inundation areas predicted bypossible tsunamis and recorded by historical tsunamis
This type of information provides tsunami hazard andvulnerable areas against tsunami in the community(Tsunami Inundation Map or Tsunami Hazard Map)
- Information for enhancing people's awareness oftsunami disaster, ensuring readiness, and reducing
tsunami damages

How to use Tsunami Disaster Management Maps
Utilization of Tsunami Disaster Management Map
・For use by residents :Enhance their self-defense abilities and promote smooth evacuation activities.
・For use by administrators and decision-makers:
Make plans for residential evacuation and for improving disaster prevention and mitigation facilities including
evacuation facilities.

Utilization of tsunami disaster management map at each stage of disaster

Educational Opportunities for Residents
Using the tsunami disaster management map in
Following-up workshop- to enhance residents' awareness of tsunami disasterprevention and mitigation- to establish the importance of the map within thecommunity
School- to continuously educate people about disasters fromchildhood- to provide a chance for family members to talk about
disaster prevention and mitigation
Residents discussing evacuation sites and routes
Voluntary disaster prevention organization in each district- to promote more precise tsunami disaster management in the district

Evacuation drills for children
It is important to implement evacuation drills for various conceivable situations, such as when elementary andjunior high school students are on the way home from school, because tsunamis may strike at any time.

Evacuation drills conducted on the way back home from school Former Taiki Town, Mie Prefecture
Informative brochure
To effectively promote residents' understanding oftsunamis and their disasters, the Susaki City Government
in Kochi Prefecture has prepared "Our Town and theNankai Earthquake and Tsunami - Let's Learn aboutTsunami," to enhance the disaster prevention ability ofcommunities.
In particular, the brochure can be easily understood bychildren, who will be future disaster managers in thecommunity and who can disseminate the information
among their family members.

Information of evacuation sites and places as wellas inundation area and striking time of the expectedtsunami results in identifying areas where it is difficultfor people to evacuate, and planning of residents' andother persons' evacuation.

Flow Chart of Making Tsunami Disaster Management map

Flow of preparing tsunami disaster management map

The tsunami disaster management map is, ingeneral, developed to add various information
on tsunami disaster prevention and mitigation ina tsunami hazard map
First step:
To indicate inundation areas predicted bynumerical simulations with possible tsunamis
and by investigations of historical tsunami
damage records.
Second step:
To add information to provide tsunami
disaster mitigation and protecing lives suchas- evacuation sites and routes, - evacuation tips
- basic knowledge of tsunami

Additional Information for Tsunami Disaster Mitigation
The tsunami disaster management map can be utilized for various purposes besides evacuation: for instance,planning of preventative measures, evaluating the effects of structural measures and others.
According to the aim of the map, necessary information is indicated on the map together with tsunami hazard
data. The map should be also prepared corresponding to intended users. Information on the map is recommended
to be presented in a comprehensive but easy to understand manner.

Recommended Method for Predicting Tsunami Inundation: Numerical Simulation
There are four kinds of inundation prediction methods:-Numerical simulation method- Level filling method- Method based on historical inundation records- Estimation based on ground elevation
The numerical simulation is recommended to predict the inundation areas, which precisely estimates distributionof inundation depth, initiation time of inundation at each point and others and provides basic data in investigatinga strategy and measures of disaster mitigation.

coasts from the tsunami source. If topographic data onland is available, moreover, the tsunami inundation areas are estimated with the numerical simulations. In recent
numerical simulations, the effect of structures such as protection works and coastal buildings in tsunami reduction
can be considered, using structure data that is obtained from airborne surveys.

Making in Workshop
Making the tsunami disaster management map in the workshops together
with residents and other representatives- to reflect local information- to promote the understanding of inundation areas and evacuation sites- to foster well-prepared persons against the tsunamis

Discussing evacuation plans at a workshop

Workshops are effective for encouraging residents to participate inpreparing tsunami disaster management maps, because it helps promote
the residents' understanding and applications of the map.

Discussing evacuation plans at a workshop
Ports and Harbours Bureau, Ministry of Land, Infrastructure, Transport and Tourism, Japan (MLIT) prepared the Japanesemanual for tsunami disaster management map. Advanced case studies have shown that the disaster management map isan effective evacuation measure.
The exploratory committee on Guideline for Development and Utilization of Tsunami Disaster Management Map
prepared a draft version of this guideline by referring to Japan's Tsunami and Storm Surge Hazard Map Manual.
