| Housing Class | Tunnel |
| Housing Description | Sensor in Tunnel 22m directly below free surface, 24m from nearest entrance. Tunnel drilled in a hill of rock in the Jura mountain. It is an abandoned military bunker with lots of tunnels. BB and EPI sensor placed on a concrete ground sitting on rock.BB sensor stays on a granite plate. EPI sensor installed 1m east of the BB sensor, directly on the concrete ground. |

Empirical Amplification |
|---|---|
| CH.BOURR..HG |  |
| CH.BOURR..HH |  |
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.
