Housing Class Urban free field
Housing Description Sensor installed within tank of a former water reservoir. Sensor on basement close to the center of the cylindrical former water tank Diameter of tank about 15 m. Building type: concrete. Building density: isolated building. Sensor placed directly on concrete floor, covered with plastic pot. The new water reservoir is located about 50-60 m from the old reservoir and it cannot be excluded that pipes run below/next to the old reservoir. A weekend house is located in a distance of about 50 m from the old reservoir. Dirt road in front of the former reservoir seems to be hiking trail in summer and winter. Distance to building: 50 m

Empirical Amplification
8D.RAW4..EH 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.
