Site Characterization

channel group
 Empirical Amplification
CH.SKAF..HG not available

Obtained from spectral modeling of small earthquakes with constant update.

  • Top: Fourier amplification with elastic (dashed line) and anelastic (solid line) amplification functions;
  • Centre: 5% damped response spectra amplification (anelastic);
  • Bottom: Number of recordings used.
