Figure 3

Examples of signal and noise spectra from stations ELO (located on bedrock) and MOR (located on conglomerate). Left panels are spectra from local events (r < 20 km) and right panels spectra from regional events (r = 138.9 km). Continuous lines represent the 80% energy S-wave spectra (both horizontal components) and discontinuous lines are the noise spectra of a 6-seconds time window choose previous to the first P-wave arrival.
