Information Boards

Information Boards can be used to provide the public with information related to tsunamis and their impact.  Useful information might be on the science of tsunamis, tsunami warnings and evacuation, & how the public should respond, and/or on the local tsunami history & past photos of tsunami impact.

Other examples of tsunami signs can be found in the 2007 New Zealand National Tsunami Signage Recommendations for Civil Defense and Emergency Management (CDEM) Groups report by the Institute of Geological and Nuclear Sciences (GNS Science Report 2007/40).

Evacuation Zones, Routes and Safe Locations

Evacuation Zones, Routes, and Safe Locations signs show the locations of the zones to be evacuated during a tsunami warning, give  instructions, directions, or routes for evacuation, and identify tsunami-safe shelters.

International Tsunami Signs - ISO-approved (2008)

In 2008, the International Organization for Standardization (ISO) approved international signage for tsunami hazard zones, evacuation areas and evacuation buildings. ISO 20712 on water safety signs and beach safety flags provides guidance on safety signs that provide information about aquatic hazards and the action necessary to avoid those hazards, including signage for tsunami hazard areas.The shape and colour required for safety signs, together with the corresponding graphical symbols, are prescribed by ISO 3864-1 and ISO 3864-3, respectively, on design standards for safety signs and graphical symbols. ISO 20712-1:2008 was developed by ISO technical committee 145, Graphical symbols, subcommittee 2, Safety identification, signs, shapes, symbols and colour.

Other examples of tsunami signs can be found in the 2007 New Zealand National Tsunami Signage Recommendations for Civil Defense and Emergency Management (CDEM) Groups report by the Institute of Geological and Nuclear Sciences (GNS Science Report 2007/40).

In New Zealand in 2008, the Ministry of Civil Defense and Emergency Management issued its National Tsunami Signage Technical Standard for the CDEM Sector (CDEM TS 01/08).  Signage is assisting in the execution of evacuation plans and is working alongside public education and response planning to strengthen tsunami risk management.   By designating a national standard for signage consistency and placement across New Zealand, it hopes to maximize recognition and understanding by both national travelers and international tourists.

ITSU-XIX said:

(Agenda Item 3.7 WORKING GROUP ON INTERNATIONAL TSUNAMI SIGNS AND SYMBOLS)

The Group accepted the “Tsunami Hazard Zone” and “Tsunami Evacuation Route” signs.

Several Member States pointed out that the use of the colour blue for a warning sign was not appropriate. The Group decided that guidance on colours should be obtained from the ISO (International Standards Organization).

The Group expressed concern over the use of text on the signs, as this would require careful translation of the text into many languages. However, it was recognized that, without text, the signs would be difficult to interpreted by the public.

The Group accepted the use of text on the signs that in their English language versions read “Tsunami Hazard Zone” and “Tsunami Evacuation Route”, but requested all Member States to submit to the IOC Secretariat, by March 2004, the language versions of the text strings for both signs in all official (and other appropriate) languages for their country.

The Group requested the Executive Secretary IOC to submit a proposal for the agreed tsunami signs to the ISO, including the different language versions, as received from Member States, and to request advice from the ISO on colour schemes.

The Group decided that there is no need to have an internationally recognized sign for “Tsunami Refuge Zone”.

The Group tasked the ITIC Director to distribute information on the adopted signs widely upon their approval by the ISO.

The Group, considering that the ad hoc Working Group had successfully finalized its work, accepted its report with the modifications made by the ICG/ITSU at its Nineteenth Session, and disbanded the Working Group.
