MotivationMotivation• Increasing number of national tsunami early warning systems (TEWS)• Increasing number of Crisis Management Information Systems (CIMS)• Research about information systems
Do we design + develop + implement + deploy interoperable information systems that are capable of system to system communication?
Or do we create more and more isolated islands?

UNESCO Tsunami ProgrammeUNESCO Tsunami Programme• UNESCO Intergovernmental Oceanographic Commission (IOC) Tsunami
Programme: o Objective: The IOC Tsunami Programme aims at reducing the loss of lives and
livehoods that could be produced worldwide by tsunamis. o Four Intergovernmental Coordination Groups (ICG) corresponding to the
regions Pacific, Caribbean, Indian Ocean and Mediterranean have been established to address particular regional needs

UNESCO Tsunami ProgrammeUNESCO Tsunami Programme
• Main objective IOC Tsunami Programme: The integration of national TEWS to ensure information exchange during tsunami events. ICG Implementation plans
• IOC ICG/IOTWS, 2008: Implementation Plan“… the establishment of a coordinated regional warning system for the entire Indian Ocean basin, through the establishment of a network of National inter-operable Warning Centres.”

ICG Implementation planICG Implementation plan• Goal: develop systems-of-systems
o Based on Standard Operating Procedures (SOP)• Legal aspects• Workflows
o Standardized ICG warning products (bulletins)• Content: What, Where, When • Format: Plain ASCII text designed for FAX transmission• No protocols, technologies, encodings
o Standardized ICG spatial reference schemas• Coastal Forecast Zones• Coastal Forecast Points

ICG/IOTWS Coastal Forecast ZonesICG/IOTWS Coastal Forecast Zones• Coastal Forecast Zones (CFZ) introduced to ensure interoperability
between TEWS

ChallengeChallenge• Develop a communication model to interlink/integrate national TEWS:
1. According to UNESCO IOC guidelines2. Accounting UN International Strategy for Disaster Reduction (ISDR)
recommendations3. Based on standards of the emergency management domain4. Applying system-of-systems engineering
• Best practices / design philosophy:o Keep it simpleo No proprietary technologyo Open standards, open source software

Information gatheringInformation gathering What are the needs and requirements? Which information must/must not be shared? Which technologies must/must not be used?
• Experiences from preceding projectso GITEWS (German Indonesian Tsunami Early Warning System)
• Literature worko IOC / ICG guidelines, implementation plans, …o ISDR recommendationso Other TEWS related researcho Crisis Information Management Systems (CIMS) in general
• Survey among expertso Questionnaires, Interviews, …

ConclusionConclusion• Simple and robust communication model
o Follows UNESCO IOC/ICG guidelineso Accounts UN/ISDR recommendationso Based on open standards (OGC, OASIS)o Reference implementation
• Open source MOM• Standard compliant (xml schema)• Tested/Validated at IOC exercise
• Deployment is not a technological problemo Longsome decision processes on high levels (political processes) o Development of information systems not driven by IT experts

OutlookOutlook• TRIDEC: EU project focussing on TEWS in Mediterranean
o Project partner: Turkey – system is running thereo Cooperation with ICG/NEAMTWSo Evaluation which countries are interested to participate
• Indonesia: Evaluation of the system with real data
• Convince IOC/ICGs to rely on open standards (Cap, EDXL)
• Long term: official IOC CAP profile for tsunami bulletins
