Laboratory Section

The Laboratory of ITSAK is mainly activated in the following fields of Nationall Network and works into the Lab:

  • Accelerograph installation
  • In situ accelerograph stations maintenance
  • Data acquisition and processing
  • Field measurements
  • Repairing of malfunctioning instruments
  • Upgrade of strong motion instruments
  • Manufacturing of auxiliary instruments
  • Remote control of accelerograph stations
  • Data analysis
  • Development of data bases

The main objective of Laboratory of ITSAK is the complete readiness of National network of accelerographs for recording seismic events every time.  This is achieved with the organization of travels of maintenance, inτο 6 months space, in situ visits, collection of data, field measurements if is necessary, repair and improvement. Till today   has been achieved the communication of all   remote stations via telephone lines (modems).

There are a number of accelerographs to establish in new places or extension of network of follow-up seismic sequences, that becomes in collaboration with the Division of Engineering Seismology and the other scientific addresses of ITSAK depending on conditions.

There are installed Special networks, which the Laboratory controls with in situ visits, or via modems, for data collection, classification and first analyses of data. Occasionally, the Technicians of Laboratory make repairs and improvements of accelerographs and extensions of existing network.

  • Chalkis High Bridge
  • Building of University Macedonia
  • Sewerage Pipe of Thessalonica
  • European Field of Trials - Mygdonia basin (Volvi)
  • Smokovo Dam  (EYDE - OSYE)
  • AHS Melitis - Achladas (NATIONAL ELECTRICAL COMPANY)
  • Bridges of Egnatias Road

The Laboratory has developed collaboration with various institutions (NATIONAL ELECTRICAL COMPANY, Ministry of Agriculture Cyprus, EYDE - OSYE, HIGHER EDUCATION INSTITUTIONS e.g.). The collaboration includes mainly below:

  1. Repair of other accelerographs by Technicians of ITSAK
  2. Education of techniques, from the services in question, on subjects of operation, installation and damage of accelerographs.
  3. Collaboration in technological programs that are worked out by the personnell of Laboratory.

The technological programs or parts of inquiring programs that are materialized till today from the Laboratory are below:

  1. Installation of 3 units ssa-2 in Smokovo dam  (EYDE - OSYE)
  2. Concretization part of the inquiring program EuroSeisrisk (Laboratory of Soil Mechanics and Foundations of Aristotle's University)
  3. Control of the system of recording seismic events in the AHS Melitis -Achladas and AHS  Atherinolakkos(NATIONAL ELECTRICAL COMPANY)
  4. Recording, control and evaluation of vibrations from shakes in the quarry of inactive materials of company "ASFALTOVIOMICHANIKI" in the place Petrwto' N. Imathia. 

Also, exists collaboration in inquiring programs, by the three Scientific Divisions of ITSAK, Earthquake Engineering, Soil Dynamics and Engineering Seismology. The object of Laboratory in the inquiring programs includes :

  • Connections between instruments
  • Wirings
  • Functional tests
  • Data collection
  • Detection and re-establishment of problems
