Earth surface deformation in Germany following the Sumatra Dec 26,2004 earthquake using 1 Hz GPS data

摘要

The Sumatra-Andaman earthquake of December 26,2004, 0:58:50 UTC was one of the largest earthquakes ever recorded and it was the first one of this magnitude (first given with M=9.0, from later studies or reports closer to M=9.3) since continuous GNSS monitoring. While deformation due to an earthquake (temporal, co- or post-seismic) in general could only be detected in local or regional distances to the centre of the earthquake by means of GPS, the horizontal surface deformation due to the Sumatra-Andaman earthquake of December 26, 2004 was large enough to be analysed with highrate GPS data even 9000 km apart from the epicentre. Results of the analyses of 1 Hz data collected at a number of stations in Germany will be presented for different parts of Germany.
