GITEWS German Indonesian Tsunami Early Warning System |
Tsunami Early Warning System (TEWS) The devastating flood catastrophy in South-East Asia on 26th December 2004 as result of a seaquake in the Indian Ocean was trigger for the Indonesian Government to decide the implementation of a Tsunami Early Warning System with German participation at the Sunda trench. It aims at the early recognition of potential Tsunami flood waves by means of seismic measurements at the seafloor, those then to evaluate and, if occasion arises, to start evacuation measures in the affected areas / coastal regions. The system comprises stations at the seafloor, offshore buoys with GPS (Global Positioning System) and land stations (warning center in Jakarta), communication is done via satellite. In case of a Tsunami the wave will be automatically detected and data will be transmitted to the warning center within a few seconds or minutes. |

K.U.M. is in so far involved in
this project as the OBS-System, modificated and adapted to the
requirements, serves as instrument carrier for the deployment in up
to 6000m depth. Beside the OBS frame made from high quality titanium, designated as OBU (Ocean Bottom Unit), the 4.5Hz titanium seismometers for ocean bottom measurements and the titanium Releaser KUMQuat K.U.M. also supplies the titanium tubes for the integration of components like sensors, recorders, modems, batteries. |
