Roland Piquepaille writes "When a powerful earthquake hit Indonesia's West Java on August 8, 2007, it took exactly 4 minutes and 38 seconds to be detected, located and sized by the German-Indonesian Tsunami Early Warning System (GITEWS) currently under construction in Indonesia. Even more remarkable, the location of the earthquake was found after only 2 minutes and 11 seconds. 'For comparison, the Pacific Tsunami Warning Center (PTWC) in Hawaii published the location and magnitude of this earthquake after about 17 minutes.' This very fast analysis was made possible by a combination of hardware and software developed in Germany. As said one German scientist who is leading the project, 'By the end of 2008 Indonesia will possess the most modern seismological network for tsunami early warning in the world.' Read more for additional references and an illustration showing the various GITEWS wireless components."
