Microearthquake seismicity and active tectonics of northwestern Greece

S-Wave Spectral Analysis and Estimation of Spectral Parameters in Northwestern Greece

“…According to Hatzfeld et al (1995), the compressional regime in Epirus is caused by the jump of active thrusting from the Pindos to the Ionian zone, which is still active at the present time. The focal mechanisms from earthquakes located in Epirus, denote thrust and strike slip to normal geological structures (Mercier et al, 1972;King et al, 1983;Doutsos et al, 1987;Underhill, 1989;Waters, 1994;Hatzfeld et al, 1995). Additional information derived from Martakis (2003), Tselentis et al (2006) and Stavroulopoulou et al (2013) seismotectonic studies in Epirus, agree with a thrust belt zone at the west, combined with an extensional regime at the eastern end.…”

“…Taymaz et al (1991), asserted that the E-W shortening generates thrust belts that trend N-NW and are cut by almost perpendicular strike slip or normal faults. King et al (1983), based on a boundary-element model proposed a substantial left lateral strike-slip component in addition to the compressional motion. In agreement with this idea are the results of the geological and geomorphological research performed by IGSR and IFP (1966) and King et al (1993) and the crustal deformation study of the Aegean area performed by Papazachos and Kiratzi (1996).…”

A spectral approach to moho depths estimation from gravity measurements in Epirus (NW Greece).

“…However, some seismic events have been attributed to normal faulting (DRAKOPOULOS and DELIBASIS, 1974;MCKENZIE, 1978) and a recent microearthquake survey in the area (KING et al, 1983) revealed that the derived fault plane solutions exhibit a variety of focal mechanisms, which are not consistent with simple zones of shortening or extension.…”

Earthquake relocation for North-Western Greece using 3D crustal model; method comparison and seismotectonic interpretation.

“…Geomorphological work performed by King et al, (1983) using boundary-element modelling, identified a substantial left lateral strike-slip component in addition to the compressional motion. Furthermore, geological and geomorphological research which was conducted by IGSR and IFP, (1966) and King et al, (1993) as well as crustal deformation studying of the Aegean area by Papazachos and Kiratzi, (1996), implied similar results.…”

“…Studies of the focal mechanisms from earthquakes within the area, have shown that the tectonic regime of the area varies from thrust and strike slip to normal (Mercier et al, 1972;King et al, 1983;Doutsos et al, 1987;Underhill, 1989;Waters, 1994;Hatzfeld et al, 1995).…”
