Three 2D seismic profiles were acquired in the Thinia valley, an isthmus connecting the main part of the island to the Paliki peninsula, to improve the subsurface knowledge of the tectonically peculiar Kefalonia island. Here the presence of a possible channel has been largely disputed in ongoing investigations for the possible location of Homer’s Ithaca. Results from different analyses further constrain the recent tectonic history of the area and thus the long-debated presence of a historic water channel in the valley.

We obtain the highest-resolution three-dimensional P-wave attenuation model in the China Seismic Experimental Site to date. The P-wave attenuation value anomalies along large fault zones, some basin areas, and the Tengchong volcanic area are low, reflecting the high degree of medium fragmentation in these areas with thick sedimentary layers or rich in fluids.
