Seismic Interferometry at the TIMO2-network, Germany

Felicitas Stein, Jörn C. Groos, Joachim R. R. Ritter
Using seismic interferometry, we analyze the seismic noise wavefield around the city of Landau, Germany. The crosscorrelation functions (CCFs) are investigated with respect to signals which might contain information on the underground and its temporal variations. The used data set comes from the TIMO2-project (TIMO: Deep Structure of the Central Upper Rhine Graben). Since the summer of 2009, seismic stations have been installed especially to detect induced seismicity in the region of Landau.
