Signal Processing Geophysical Data Analysis

IUSS Pavia
ES - Engineering Seismology
Spring 2014
Date (from - to):
03/02/2014 – 28/02/2014

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 course will start with signal processing techniques (20 h) to understand the information in seismic records and highlight how to process seismic data correctly to obtain information about Earth structure, resonance frequencies, time delays etc. After an introduction to the theoretical framework of signal processing, the main part of the signal processing will be organised around practical work on simple signals as well as on field data.
  • The second part of the course deals with applied seismic (35h): refreshing and introduction to geophysical techniques, refraction seismic, inversion theory, seismic tomography, reflection seismic and surface wave inversion. 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. It includes 7 two‐hour lectures, 4 two‐hour practicals and a field work day with 4 hours of data interpretation.
  • 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.
