Site Characterization

channel group CH.ACB..HH
Empirical Amplification not available
channel group CH.ACB..EH
Empirical Amplification not available
channel group CH.ACB..HG
Empirical Amplification 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.
