The system includes a seismological network, together with GPS stations and a network of GPS buoys additionally equipped with ocean bottom pressure sensors and a tide gauge network. The different sensor syst...

Indonesia is located along the most prominent active continental margin in the Indian Ocean, the so-called Sunda Arc and, therefore, is one of the most threatened regions of the world in terms of natural hazards such as earthquakes, volcanoes, and tsunamis. On 26 December 2004 the third largest earthquake ever instrumentally recorded (magnitude 9.3...

The Tsunami of December 26, 2004 in the Indian Ocean caused one of the largest natural disasters in history. Since 2005 a tsunami early warning system has been developed as reactive response to this disaster. The article describes the causes of the tsunami, the technical components of the early warning system and the functionality of the system.

No abstract available.

The Tsunami Early Warning System for the Indian Ocean just recently went into operation in Indonesia. The different sensor stations have, for the most part, been installed and now deliver respective data either online or upon request to the Warning Centre in Jakarta. Before March 2010, however, the interaction between the different component parts...

The system conception combines terrestrial observation networks of seismology and geodesy with oceanographic instrumentation such as tide gauges and buoys and is installed mostly in Indonesia, but also in adjacent countries. GITEWS is realized as an open system to ensure that different components or sensors respectively, can be added if necessary t...

Am 26. Dezember 2004 überraschte ein Tsunami verheerenden Ausmaßes die Anrainerstaaten des Indischen Ozeans und zerstörte in wenigen Augenblicken das Leben von rund 230.000 Menschen sowie Hab und Gut weiterer Millionen. Auslöser war ein Erdbeben der Stärke 9,3 vor der Küste Nord- Sumatras. Die damalige Bundesregierung beschloss daraufhin eine umfas...

First milestones on the road to an effective Tsunami Early Warning System for the Indian Ocean have been achieved.

The Central Andes are the Earth's highest mountain belt formed by ocean-continent collision 1,2. Most of this uplift is thought to have occurred in the past 20 Myr, owing mainly to thickening of the continental crust 2-6, dominated by tectonic shortening 7-10. Here we use P-to-S (compressional-to-shear) converted teleseismic waves observed on sever...

We present the results of a detailed shear wave splitting analysis of data collected by three temporary broadband deployments located in central western South America: the Broadband Andean Joint experiment (BANJO), a 1000-km-long east-west line at 20°S, and the Projecto de Investigacion Sismologica de la Cordillera Occidental (PISCO) and Seismic Ex...
