Housing Class Urban free field
Housing Description Both sensors on the ground floor next to the south-western wall of a small one-storey abandoned bunker with a equilateral hexagonal ground plan and an side length of the outer wall of 3m. EPI sensor is installed 80cm south-east of the Tr.240s Building type: concrete. Building density: isolated building. Building usage: used for storage. Sensors placed on concrete floor.

Site Characterization

channel group
Empirical Amplification
CH.CHASS..HH not available
CH.CHASS..HG 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.
