“…The WNW-ESE trending grabens of this system (Gulf of Corinth and Megara Basin) are associated with listric normal faulting (Zelilidis et al, 1988) trending at the same direction and are associated with shallow earthquakes (Brooks and Ferentinos, 1984;Jackson et al 1982). The trending WNW subsiding areas in the immediate vicinity, like the Prevesa Gulf, Trihonis lake and the Corinthian Gulf are also associated with ENE trending faults (Doutsos et al, 1985) (Figure 2).…”

“…From a tectonic point of view, Patraikos Gulf area consists the western part of a major East/West graben system, behind the Plioquaternary fold belt (Doutsos et al, 1987). This graben system extends from the boundary of a marginal compressional zone (Brooks and Ferentinos, 1984) associated with the subducting Western Hellenic arc, to the center of the Aegean Sea (Figure 2). …”

“…The case study area is located on the northwestern part of the tectonically active Gulf of Corinth which is an asymmetric graben in central Greece trending NW-SE across the Hellenic mountain range, approximately perpendicular to the structure of Hellenides (Brooks & Ferentinos, 1984;Armijo et al, 1996). The western part of the gulf, where the study area is located, is presently the most active with geodetic extension rates reaching up to 14-16 mm/yr (Briole et al, 2000).…”

“…Perissoratis et al, 2000 estimates from seismic reflection images an average sedimentation rate of about 0,25 mm/a and 850 000 tons per year sediment influx. The subsequent erosion has resulted in depositions of up to 1 km of sediments in the Gulf (Brooks & Ferentinos, 1984, Ferentinos, 1984, Higgs, 1988. calculated 5 km thickness of Pleistocene sediment due to the observed uplift history in the footwall regions south of the Gulf, whereas Westaway, 2002 required no more than 1 km of sediment loading using a numerical model.…”

PrefaceIn this thesis the thermo-hydraulic conditions of a seismically active zone have been investigated by means of surface and subsurface investigations, borehole studies and numerical modeling. European research activities in the Gulf of Corinth have been targeted for obtaining data on earthquake sources and fault mechanics and for investigating the role of faults on fluid flow in this seismically active area. In this context, the DFG funded a project aimed at the exploration of the thermo-hydraulic conditions in the area near Aigion and the southern graben shoulder of the northern Peloponnesus including the determination of surface heat flow in a 1000 m deep borehole, which is the scope of this work.First, due to a lack of geological information, a detailed investigation of the geological and tectonical situation was made. Secondly, the hydraulic parameters of the different lithological formations and of the hydraulic behavior of normal faults were determined.Based on the field studies, hydraulic testing, petrophysical well-log analysis, optical-fiber temperature sensing, and laboratory measurement of thermal conductivity, a hydrogeological conceptual model was prepared. This conceptual model formed the basis for a numerical 2-D model of the hydraulic conditions at regional scale at the southern Corinth graben shoulder. Different simulation scenarios were investigated to search for the best-fit model to known parameters.Coupled numerical modeling of groundwater flow and heat transport was then used to get insights in the processes that may be typical for the study area. In the case of the Corinth area, model calibration, as well as sensitivity and plausibility checks allow a prediction on how the thermo-hydraulic system in this seismically active zone is characterized and how the hydraulic conditions affect the heat flow. Surface heat-flow density was unknown in the northern Peloponnesus prior this study. Also unknown was whether the water flow in aquifers results in strong heat advection signals in the temperature field.The coupling of temperature and geothermal parameters to the calibrated hydraulic flow model has shown that some of the intervals are affected by heat advection due to fluid flow, affecting the temperature gradient and hence the heat flow. In a pure conduction heat regime the measured temperature of 32°C from 750 m depth would be increase to 37°C. At the lower model boundary of 1155 m depth the maximal temperature in the conductive 1-D temperature profile is 45°C which is approximately 4.5°C higher than in the coupled thermo-hydraulic flow model. The examination of coupled modeling runs has shown that conductive heat flow of the crust is about 55 mW/m². Finally, it is clear that the quality of input data is playing a major role for the best fitting of a numerical model. Otherwise it was also shown that sometimes generalization is necessary when general restrictions from the modeling software are required. Undoubtedly, the fault zones of the Gulf of Corinth are representing one case...
