Installation of two accelerometric stations at a steel water tank of EL.PE. company in Kalochori

Within «D2.2: Design and implementation of permanent Aceelerographic and GNSS network» action of INDES-MUSA research program, a set of two 24bit accelerometric stations were installed on 16th of January 2014 at a steel water tank of EL.PE company in Kalochori. The exact locations of the stations shown in Figure 1 meet the research needs of seismic motion monitoring and study of soil-structure interaction within the tanks zone of the broader Kalochori region.

The first accelerometric station (KLH5) was installed at the centre of the tank roof. Technically KLH1 was placed on a steel base that was specially designed, constructed and welded to the tank roof by EL.PE. company (Figure 2), allowing the instrumentation of a representative structure of the tank region in Kalochori.

The second accelerometric station (KLH6) was installed on the ground at a close distance from the tank’s base to avoid possible interference between soil and structural motion in the acquired data [Figure 3]. Thus, KLH6 may be considered as an urban free-field installation within the particular zone of interest.

Both stations were configured on a continuous recording data stream and local storing of the recordings. A future upgrade of the installations to allow real time data transfer at the central INDES-MUSA server of EPPO-ITSAK premises in Thessaloniki is scheduled.
