Need for
Disaster Relief & Early Warning
 Disaster results in loss of human lives & displacement of
millions of people
 Communication system can play a great role to provide early
warning and disaster relief
 Early warning is a key element for disaster prevention and
reducing loss of human lives from view point of victims
 Disaster relief can make victims to capture the correct
information on rescue parties, relief supplies, damage
situation and safe confirmation. And also it can provide their
friends and relatives with the situation of individual victim

Effectiveness of Mobile System
based on our experience March 11, 2011
 Many victims run off with mobile terminal
in hand after a disaster
(e.g. Japan Earthquake and Tsunami, March 11, 2011)
 Higher mobile penetration ratio than fixed telephone
 Disaster warning also provided by conventional
broadcasting services such as TV and Radio
 TV & Radio to provide an information to general public but
not to individual
 Mobile to provide information not only to general public but
also individual

Categories of
Disaster Relief & Early Warning
1. Early Warning (To warn of a coming potential disaster or a
occurred disaster )
2. Disaster Relief for general public (To notify latest support
situation after disaster)
3. Disaster Relief for individual (To notify damage situation from
victims to their relatives, friends, acquaintances, co-workers
and boss)
4. Disaster Relief by guidance (To guide each victim a route to
evacuation shelters and to his home )

Customer preference for real time voice
< Transition of customer demand request>
Instantly, customers tried to make voice calls to their relatives and friends for confirmation of safety. (First
preference was real time voice)
⇒ After voice traffic was congested & controlled, customers’s request changed from voice call to messaging service.
(Peaked at 15 minutes passed)
⇒ ・The number of registration on “ Message board” had been increased . ( Peaked at 2 hours passed)

Earthquake Early Warning System
 What is the earthquake early warning system? (Started from Mar. 2008）
 Earthquake Early Warning (EEW) originated at Japan Meteorological Agency (JMA) is broadcasted to
au mobile phones in areas around the seismic center, free from congestion.
 An alert with a dedicated alarm tone, vibration, and display on a mobile phone screen.
 Only when a maximum Seismic Intensity” Scale 5” lower or more is estimated, the EEW is broadcasted
to the areas where a Scale 4 or more is foreseen.

 How did EEW work on the Mar. 11 disaster?
 Effective to notify people of the earthquake
 Not useful to notify people of the tsunami, however
Currently, KDDI supports the tsunami warning.(2012.3.30~)

After a disaster, Disaster Voice Mail Service is provided. The voice is
packetized and to be stored & forwarded in Packet Network.
This service has been launched since June 4, 2012

Conclusion at CTO Meeting Geneva
Communique, 25 October 2011
Emergency Communications:
The year 2011 has been marked by a series of natural disasters, notably
the tsunami and earthquake in Japan, so an essential item on the agenda
was the role of ICT in disaster relief. Communication systems can play a
key role to provide early warning and disaster relief and are a critical
element of managing disaster prevention and reducing loss of human life.
While ITU has a number of important activities to address disaster relief
and prevention, the CTOs observed that two important areas have not
been addressed:
(1) Disaster Relief for individuals (to notify the damage
situation from victims to their relatives, friends, employers)
and (2) Disaster Relief Guidance (to show victims the routes
to evacuation shelters, home, etc.)
They called on ITU-T to urgently study the development of standards for
disaster relief systems for individuals and for guidance and to establish a
Focus Group to advance work on this critical subject, including the
recovery and resilience of network infrastructure.

Work Items for Disaster Relief & Early Warning
<Extraction from CTO MEETING GENEVA COMMUNIQUÉ, 25 October 2011>
 to identify all the possible use cases for Disaster Relief
systems, especially Disaster Relief for individuals and
Disaster Relief by guidance
 to identify requirements based on the use cases, and to
develop related ITU standards needed
 to recognize that many victims run off with mobile terminal
in hand after a disaster
 to recognize convenience of graphical guidance on mobile
devices from view point of victims
 to consider scalable vector graphics (SVG) as a key
technology for graphical maps on mobile devices.
17
Cooperation with W3C
on scalable vector graphics (SVG)
 Map guidance to Evacuation shelter, Hospital etc is a
powerful tool for Victims.
 Map technology under disaster is required to satisfy:
①All mobile terminals to be interoperable (Open)
②Multiple info. to be easily overlaid on one map
③Map guidance to be operated without
communication with outside server (no radio signal )
 SVG map as a part of HTML5 satisfies the above
 SVG map is under development by W3C
⇒ Cooperation with W3C is required
