25 Vulnerability analysis and risk assessment Joint Indonesian-German working group Workshop, Aug. 2006, Bandung Mapping the city of Padang based on high-resolution satellite data

26 Risk & vulnerability assessment Coastal Elevation Zoning Major Road Net Identification of infractructure and its degree of exposure (e.g. Padang) Official and Public Buildings

27 Capacity Building Academic programme & Technical work shops Training of scientist and engineers during installation phase ( Training on the job ), Workshop planned for Spring 2006, eight PhD positions for applicants from IORC ( sandwich programme ), Scientists exchange has started Consultancy to organizational structures and inter-institutional communication (government at different levels) Advices for planning and construction of new infrastructures, establishing of communication platforms and chains Establishment of warning mechanisms within three pilot regions GTZ staff in charge in Indonesia since summer 2006, training for last mile actions in Padang, South Java & Kuta/Sanur (Bali)

28 Training and Capacity Building Training Course Seismology, Data Analysis and Tsunami Detection 29 Jan 18 Feb 2007 in Jakarta Organized by: GFZ Potsdam, BMG Jakarta and USGS 30 Paticipants PhD-Program with 9 Scholarships for 3 years at german research institutions started this year Participants from Indonesia, Malaysia, Madagascar Post-Doc Programe for the exchange of Scientists (2-4 Months) started

29 Seismology, Data Analysis and Tsunami Detection 29 Jan 18 Feb 2007 in Jakarta

30 International GNSS-Altimetry Activities German activities are realized under UNESCO s umbrella IOC : Intergovernmental Oceanographic Commission ICG: Intergovernmental Coordination Group Intersessional Working Groups: 1: Seismic measurements, data collection, and exchange 2: Sea level data collection and exchange, including deep-ocean tsunami detection instruments 3: Risk Assessment 4: Modelling, Forecasting, and Scenario Development 5: The Establishment of a System of Interoperable Advisory and Warning Centres 6: Mitigation and Emergency Management (NEW!) Involvement into EC/EU activities as well as in NEAMTWS (IOC)

31 International Cooperation Yemen Sri Lanka Kenia Tanzania Maldives Indonesia South Africa Australia

32 GPS GLONASS GALILEO Satelliten constellation as component of a future Multi Hazard Early Warning System

33 End-to-end System Approach Enduser Authorities EWMC Warning Message Radio Station Private Houses Hotels 2wcom System based on existing FM broadcast infrastructure Using the RDS-channel for warning System tested successfully in Bali
