Engineering Seismology

Engineering Seismology focuses on applied research and validation in various fields of Seismology, Engineering Seismology and Applied Geophysics.

The research topics include:

1. Applied Geophysics

Shear Wave Velocity Model from Array Recordings

  • Reflection, refraction, Cross-Hole and Down-Hole surveys for revealing the structure of the subsurface layers

  • Single station and array microtremor surveys for evaluating the physical properties of the uppermost soil layers and their response characteristics

  • Local and regional surveys using electromagnetic induction methods for recognizing different structures from the surface (sediments) to deeper layers (bedrock) as well as for providing information on the geometrical characteristics of faults.

2. Seismology

  • Seismicity studies including research of earthquake distribution by size in space and time.

  • Studies on time independent and time dependent seismicity models.

  • Fractal and multifractal spatial distribution of earthquakes in Greece.

  • Seismotectonic studies for the compilation of reliable seismic source models

3. Engineering Seismology

  • Development and improvement of numerical data processing techniques for the correction of accelerograms.

  • Contribution to unified European (http://www.isesd.cv.ic.ac.uk/) and National strong-motion databases (HEAD_v1.0) for scientific and engineering uses.

  • Compilation of empirical predictive relations of strong ground motion parameters using records mainly of ITSAK networks (permanent and temporary).

  • Probabilistic seismic hazard studies in terms of various seismicity and seismotectonic models of area and hybrid types (areas and faults).

  • Contribution to a databank of macroseismic information consisting of 30000 observations, compiled in cooperation with the Geophysical Laboratory of the Thessaloniki University, and used for the validation of the results of site specific seismic hazard studies.

  • Deterministic seismic hazard studies based either on the deaggregation of seismic hazard results or on the maximum credible earthquake of the nearby faults. Both the Empirical Green's Functions and the Stochastic Simulation methods were used

  • Site effect studies using strong motion data as well as ambient-noise recordings.
