Scientific coordinator : Dr Filippos Vallianatos (Professor, Dept. of Natural Resources & Environment)   


list of participants

    The Geophysics and Seismology Laboratory of the Technological Educational Institute of Crete (GSL) has been ceaselessly contributing to the advancements made the past 10 year in the field of Geophysics and Seismology in Crete. In the course of its activities over the years, a better understanding of the seismicity and the seismic risk of various areas of South Aegean were accomplished. At the same time a large number of microzonation studies contributing in seismic hazard mitigation was performed and many local seismic station networks for monitoring and determining the seismotectonic regime of the certain areas- were deployed. Certain applications of theoretical aspects of seismology to Greek data resulted in revised and/or local seismic intensity and seismic energy attenuation laws and in the determination of seismic source parameters for a large number of events. In recent years, major advances were made ίn the field of Geophysics, due mainly to the application of dynamic, seismic, electromagnetic and magnetotelluric methods. Emphasis was imposed on the application and of modern methodologies, i.e. seismic and geoelectric tomography, high resolution seismic reflection.

    GSL is concerned both with the understanding the cause and mechanism of earthquakes and with determining the structure of the earth's interior, using seismic waves and other geophysical methods.

    The group includes seismologists, geophysicists and rock physicists.

    The mission of GSL is to:

·         Operate a network of seismic stations in the Crete region; Analyze the data obtained with the Crete seismic network;

·        Compile data on historic and current earthquake activity in and around the region of Crete, exchange of information on earthquake activity in S. Aegean with other Research Institutes and Universities

·         Provide for education of the public in matters related to seismicity and earthquake risk in the Crete  region;

Carry out grant- and contract- supported research on earthquake problems;

    Geophysics and Seismology both theoretical and applied are major areas of expertise, in which GSL has accumulated years of experience. GSL employs the most advanced technology available in Seismology and Geophysics. As a multidiciplinary quantitative research field, the new advances in electronics and computer technology are immediately adapted into the projects being carried out. Our greatest research strengths are in network seismology, tectonics, earthquake source physics, earthquake hazard research, exploration seismology, and theoretical seismic wave propagation, Seismicity and Aftershock Studies, Engineering Seismology, Earthquake Site Effect Evaluation, Earthquake Risk and Seismic Hazard Evaluation, Mapping of Earthquake Faults by Remote Sensing & GIS Applications, Seismic Data Processing, Modeling and Inversion.

    GSL maintains ns a seismological networks over the entire region of Crete and S. Aegean (frontal part of the Hellenic Arc). Its research staff also has extensive experience with rapid deployment, maintenance and analysis of temporary networks for seismological and engineering studies. Such expertise has been expanded through participation in national and international research programmes.  GSL  is able to offer its services in:

  • Seismic Risk investigations in rural and/or urban areas and at sites of major infrastructures.

  • Microzonation studies for seismic hazard mitigation in cities or other populated areas.

  • Studies of seismic precursors tracing in areas of high or low seismic activity.

  • Seismic source and strong ground motion research for designing major infrastructures.

  • Seismotectonic studies for the location of active faults.

  • Structure vulnerability due to potential seismic load in conjunction with soil category.

  • Designing emergency response scenarios to potential earthquake disaster in specific regions.

  • Seminars, lectures and publications aimed to inform the public on earthquakes and on the means of protection and hazard mitigation.

  • Geophysical research

  • Problem solving in engineering seismology and geology i.e. identification of the depth and topography of the base rock for the foundation of major bridges, dams and port infrastructures.

  • Seismic tomography studies. Geoelectric tomography studies, Cross-hole, Seismic refraction and Seismic reflection studies.

    The development of Geophysical and Seismological is a scientific target of the research group in GSL. The Laboratory has an extensive and indigenous experience in the design, construction and maintenance of geophysical instrumentation and telemetric networks for surveys in seismic and volcanic areas and the continuous monitoring of geophysical fields. GSLs’ research team to be involved in this project comprises an effective blend of highly qualified scientists in the research topics of seismology-geophysics, geophysical instrumentation and geoinformatics. The accumulated experience of the members of the Greek research team is a consequence of their extensive involvement in large number of national & international research programs, in co-operation with European and Japanese Universities and Research Institutes.
