The course intends to introduce seismic techniques in earthquake engineering, with specific reference to active seismic exploration and passive techniques for soil and building investigation.

  • The first part of the course deals with applied seismic: refreshing and introduction to geophysical techniques, refraction seismic, inversion theory, seismic tomography, reflection seismic and surface wave inversion.  
  • The second part of the course aims at providing both a fundamental basis and a practical knowledge on the seismic techniques  applied for imaging the sub-surface and characterizing the soil layers, with a focus on the shear-wave velocity determination.
  • The third part is focused on the building behaviour assessment using ambient vibrations for structural health monitoring and extracting dynamic parameters of existing buildings. This part includes 4 hours of field experiment for recording ambient vibration buildings or bridges and 4 hours for data interpretation.
