TODO - During a 7-week microearthquake experiment conducted in Epirus,
Akarnania, and the Ionian islands of western Greece, we located
approximately 600 earthquakes with magnitudes between 2 and 4.2. No
event was deeper than 40 km. The seismicity cannot be clearly associated
with any single fault except the Lixourion right-lateral fault located
west of the Ionian islands. Focal mechanisms of about 100 earthquakes
show, for a narrow band of earthquakes located along the coast, ENE-WSW
shortening consistent with the surface tectonics. Farther east, focal
mechanisms show NNW-SSE extension beneath the foothills of the Pindus
mountains, which is unrelated to surface faulting but is consistent with
the presently subsiding basins. This strain pattern is seen far north
and south of the Lixourion fault and is similar to the one observed in
the Peloponnese. It suggests that a large-scale mechanism is responsible
for the recent geodynamics of both the northwestern and southwestern
Aegean
