Broadband Seismic Noise: Classification and Green's Function Estimation
Jörn Christoffer Groos · Repository KITopen (Karlsruhe Institute of Technology) · 2010
This thesis aims at a better understanding of the spatial and temporal variations of the amplitudes as well as the statistical properties of the (urban) seismic noise. A new statistical time series classification is presented which is used to conduct an analysis of the spatial and temporal variations of seismic noise between 8 mHz and 45 Hz in a metropolitan area. Furthermore, it is used to realise data selection approaches for the estimation of Green's functions from seismic noise.
