| Housing Class | Tunnel |
| Housing Description | Sensor in tunnel, 33m directly below free surface, 55m from nearest entrance. Tunnel system is several hundred meters long and is rarely used by power plant operators. The distance from the sensor to the eastern top end of the dam is 345m. BB-Sensor stands on marble plate, placed on ~40cm high concrete pedestal on rock. Epi sensor installed 2m west of the broadband sensor, on ~40cm high concrete pedestal on rock. |

Empirical Amplification |
|---|---|
| CH.SENIN..HH |  |
| CH.SENIN..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.
