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

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)
