  1. GITEWSGerman Involvement for a Tsunami Early Warning SystemTide Gauges

  2. Components of a Tsunami Early Warning System • (1) Real-Time Earthquake Monitoring • Seismology: Location and magnitude in a few minutes • Deformationmeasurements by GPS • (2) Real-Time Sea-Level Monitoring • GPS-Buoys with ocean-bottom pressure sensor • GPS equipped Tide Gauges • (3) Tsunami Simulation • (4) Installation of National/Regional Data- and Early-Warning Centers • (5) Capacity Building

  3. Concept for a Tsunami Early Warning System + strong motion + GPS sensors + strong motion + GPS sensors + seismic

  4. Preliminary GEOFON/BMG Station Gunungsitoli (Nias)

  5. Tsunami Buoy-OBU System Tsunami-Buoy GPS-Antenna Communication Windgenerator Ocean-Bottom-Unit Meteorological Instruments Solar Panels Acustic Modem Ocean Bottom- Seismometer Pressure Sensor

  6. German Contribution • Around 20 CGPS@TG • Radar Gauge + 2 others (pressure / float) • Additionally High Rate GPS, VSAT, Strong Motion • „Joint Declaration“ with Indonesia • Request by IOC for 5 additional TGs • Currently, focus to Indonesia (10 tide gauges)

  7. MSL GPS Radar Gauge GPS Receiver Computer INTERNET/Phone Power Supply Pressure Sensor 1 Notes: Sporadic leveling between ARP and Pressure Sensor 1 (MSL) Power supply either 230V with Backup-solar-power or solar power only Pressure Sensor 2

  8. MSL GPS Radar Gauge GPS Receiver Computer INTERNET/Phone Power Supply > 500 m Pressure Gauge Notes: Regular (once per year) 1st order leveling Power supply either 230V with Backup-solar-power or solar power only Pressure Gauge

  9. Pressure 1 Pressure 2 Radar 1 Design for Tide Gauge Stations within the Tsunami Warning System GPS Seismo Meteo Solar ~~~~ (optional) PC104 Linux Data Logger HF/WLAN RS232 Sat-Comm GSM Solar

  10. BAKOSURTANALProposal for new tide gauges Up to 10 GPS-equipped tide gauges

  11. Installation September 2006

  12. GITEWS: cGPS@TG Sadeng, Java • Tidal house building: • Radar Gauge • Pressure Gauge and Floating Tide Gauge • GPS • Pole staff • To be added: GTS, VSAT

  13. Float and Pressure Gauge

  14. Solar Power Array

  15. GITEWS: cGPS@TG Telukdalam, Nias GPS marker • Tidal house building: • Radar Gauge • 2 Pressure Gauges • Pole staff • To be added: GTS Leveling markers Pole staff

  16. GITEWS: cGPS@TG Telukdalam, Nias GPS antenna • GPS building: • Computer • GPS Receiver • Communication equipment (PASTI) • To be added VSAT Leveling marker (one out of three at land)
