Seismic activity in the Lower Rhine Embayment between Cologne, Bonn, Düren, Jülich and Aachen belongs to the highest in Europe north of the Alps. In the flat sediment basin site-effects are very important for the seismic hazard analysis.
Goal of this PhD-project of the Department for Earthquake Geology at the University of Cologne is to examine the influence of the local geology on amplitude, duration and frequency content of the earthquake ground motion. Of particular interest is the nonlinear absorption behavior of the unconsolidated sediments.
