Site Characterization
|
channel group |
Empirical Amplification |
|---|---|
| CH.SCME.BT.HG |  |
| CH.SCME.SF.HG |  |
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.
