A Call to Action … 26 December 2004250,000 dead, 500,000 injured

1 million displaced

$8 billion in damages

“We cannot stop natural calamities, but we can and must better equip individuals and communities to withstand them.”UN Secretary-General Kofi Annan


Plate Tectonics

Active subducting plate boundaries



  • 1965 - response to 1960 Pacific-wide Chile tsunami

IOC established ICG/ITSU (now ICG/PTWS)

Intergovernmental Coordination Group for the Pacific Tsunami Warning and Mitigation System

ioc core system implementation
IOC: Core system implementation
  • Governance
    • 2 intergovernmental coordination mtgs
  • Capacity building
    • Expert advisory missions
    • Startup training programme
  • Core system observational network
    • Interim advisory information service
    • Operational sea-level and seismic network for tsunami monitoring
what is the system
What is the System?

The system must be:

  • Fully owned by Indian Ocean countries
  • Based on international and multilateral cooperation
  • Based on open and free data exchange
  • Protect all countries in Indian Ocean
  • Transparent and accountable to all countries
how does it function
How does it function?
  • Based on joint operation of international networks of detection connected with national tsunami warning centres
  • High-level commitment by country with UN governance provided under the IOC
  • Each nation is responsible for issuing warnings in their territory and for protecting its own population.
  • National centres must have strong links with emergency preparedness authorities (national, provincial and local)
indian ocean where are we now
Indian Ocean Where are we now?
  • A single system planned

All countries of the Indian Ocean participate

  • Interim Tsunami Advisory Information from centres in Hawaii and Tokyo.
  • Natl 7/24 Tsunami Focal Points in 26 nations
  • Governance - UN/IOC through ICG/IOTWS
  • Full scope of task recognized:

multi-nation (28), multi-year (>3 to 10+ yrs)

  • Joint UN implementation: IOC, WMO, ISDR, UNDP, UN-ESCAP
March & April 2005: Considering the devastating tsunami on Dec 26th 2004, two International Coordination meetings on the Development of an IO TWS took place in Paris and Mauritius

16 National Assessment Missions


Sea level stations being deployed

  • March 3-8: UNESCO/IOC 1st Regional Technical Coordination Meeting, Paris
  • April 14-16: UNESCO/IOC 2nd Regional Coordination Meeting, Mauritius
  • June 21: IOC General Assembly, Paris: Formal establishment of ICG/IOTWS
  • August 3-5: ICG/IOTWS-I , Perth: focus on technical aspects
  • December 14-16: ICG/IOTWS-II, Hyderabad: recommendations & commitments
initial system for july 2006
Initial System for July 2006
  • Based on Existing:
  • Network of 26 (of 29) National Information Centres [7/24]
  • Tsunami Focal Points [7/24]
  • Slowly evolving into a
  • Network of Tsunami Warning Centres in charge of
  • National Mitigation Plans (Assessment, Warning, Preparedness)
  • Need to develop Regional Instrumental Networks:
  • Improved Seismographic network (faster and more accurate detection of earthquakes through denser network, better real-time source characterization)
  • Real-time network of sea-level stations (faster detection of tsunamis through denser network)



Core IOTWS Seismographic Network

Agreed on Stations


May-Sept, 2005: 16 missionsTo be scheduled, 2006: 6 missions Maldives, Djibouti,East Timor, Iran, South Africa, YemenNot requesting: Australia, France, India, Singapore, United Kingdom

5 Tsunami Mitigation Categories:

  • Contact information
  • Authority and coordination
  • Warnings and tsunami monitoring
  • Warning response and Emergency Action / Preparedness
  • Hazard and risks
  • Community/Individual awareness and preparedness
  • Tsunami response to 28 march 2005 M8.5 earthquake off Sumatra, Indonesia

summary regional cb needs
Summary: Regional CB Needs
  • Assistance -harmonize existing practices / protocols

Data collection, monitoring, evaluation, warning comm

International standards and interoperability

  • Assistance toestablish real-time regional / local seismic and sea level networkswith real-time data acquisition, display, and analysis to support the monitoring / detection
  • Equipmentupgrade and capacity building in Global Telecommunication System(GTS) to NMS

the challenge
The Challenge
  • We essentially know what is needed at the country level in 16 countries

Work for rest of countries will be completed in 2006 (6 countries)

  • ICG is requesting a Comprehensive IOTWS Plan, including the Country level
  • Therefore, we need the development of the National Plans at the Country level.

A perfect warning will be useless

if people do not know what to do

in case of an emergency

Awareness and preparedness at the country level is essential
