Comparison of inter-station Green’s functions from ambient noise cross-correlations (black) with synthetic (red) assuming a single force excited at UEMC09. Both waveforms were band-pass filtered between 0.125 and 0.177 Hz (left), 0.177 and 0.250 Hz (middle), and 0.250 and 0.354 Hz (right). The inter-station distance is indicated below the station name. a Transverse component due to a single force in direction T+. The amplitude is normalized by the maximum amplitude of the transverse component. The red arrow indicates the fundamental mode of the Love wave. b Radial component due to a single force in direction R+. The amplitude is normalized by the maximum amplitude of the radial component. The blue arrow indicates the fundamental mode of the Rayleigh wave. The purple arrow indicates the secondary prominent wave packet. c Vertical component due to a single force in direction R+. The amplitude is normalized by the maximum amplitude of the radial component
