On December 26, 2004, one of the most severe earthquakes hit Indonesia, on the northern tip of Sumatra in the Indian Ocean. As a consequence a devastating tsunami killed more than 230,000 people in Indonesia and the neighbouring countries.
A german team of scientists headed by the German Research Centre for Geosciences (GFZ) helped Indonesia to develop and install a tsunami early warning system for the Indian Ocean. The system was taken in operation in 2008 and assigned to Indonesia in 2011.
The following picture gallery explains the different aspects and componentes of the early warning system.
