Active Faulting and Seismic Hazard in Attiki (Greece)

To understand the implications of active faulting, surface fault loading process, the interaction of faults, lithospheric processes and wave propagation for the seismic hazard in the region of Athens (Greece).

Two different scales:
At a local scale, the Gulf of Evia.
The relationships among the total deformation, the seismic energy release and the deep structure of a very active area which is the Gulf of Evia, for comparison and possible connection with the Gulf of Corinth.
At a regional scale, the Aegean.
The relationships among the major seismogenic zones, the crustal and mantle structure, and the ground motion.

To use the region in Europe with the most rapid deformation and the highest seismicity for seismic hazard mitigation in countries of slower deformation and moderate seismicity.

Local scale, Evia
The study of an active normal fault system.

Map precisely the active faults.
Quantify their displacement both in space and time.

Monitor the rate of deformation with 2 GPS profiles across the Gulf.
Define the distribution of faulting and strain.

Maintain the VOLNET and CORNET seismological networks.

Install 2 profiles across the system Gulf of Corinth-Gulf of Evia.
Locate and study the crustal and upper mantle structure.

Compare the mechanics of the Evia and Corinth regions.
Understand the dynamics of such system of faults.

Regional scale, Aegea

The implication of seismic sources and the earth structure on the ground motion.
Install a network of 30 broad-band seismometers over the Aegean for a 6-month period to:
Locate shallow and intermediate depth earthquakes and estimate the source characteristics.
Compute the heregeneous velocity structure.
Determine the attenuation laws for ground shaking.
Measure the anisotropy of seismic wave propagation.
