	abstract = {<div>A submarine survey along the coasts of Ithaca and Fiscardo has permitted the\&nbsp;identification of fossil shorelines produced by recent co-seismic movements.\&nbsp;In both areas a tidal notch slightly submerged below present MSL was observed at\&nbsp;various sites. This {\textquotedblleft}modern{\textquotedblright} notch is known to have been submerged by the global\&nbsp;sea-level rise during the 19th and 20th centuries. The depth after tide and air-pressure\&nbsp;correction of the vertex of the {\textquotedblleft}modern{\textquotedblright} notch (= MSL before the recent sea-level\&nbsp;rise) was measured between -19{\textpm}6 and -25{\textpm}6 cm at Fiscardo and between -34{\textpm}6 and\&nbsp;-43{\textpm}6 cm at Ithaca. The presence of this {\textquotedblleft}modern{\textquotedblright} notch at the same depth on both\&nbsp;sides of the Ionian Thrust would give evidence that both areas were not affected by\&nbsp;the co-seismic vertical movements that occurred in 1953 in the wider area, while a\&nbsp;greater depth in Ithaca could be an effect of co-seismic subsidence. Both cases are\&nbsp;discussed and analysed in this paper. Assuming that the development of the\&nbsp;{\textquotedblleft}modern{\textquotedblright} notch was produced by bioerosion, it is possible to deduce a period of\&nbsp;relative sea-level stability before the 19th century during 2.4 to 4 centuries at Ithaca\&nbsp;and 1.5 to 4 centuries at Fiscardo.\&nbsp;Over the longer term, the tectonic behavior of Ithaca differs from Fiscardo. At\&nbsp;Ithaca no evidence of emergence has been found and Holocene vertical movements</div>
<div>have been only of subsidence: fossil submerged tidal notches can be distinguished\&nbsp;below MSL at depths ({\textpm}6 cm) of about -40 (modern), -60, -75, -90, -100, -120, -130,\&nbsp;-140, -150 and -220 cm. A southward tilting of the island is suggested from the -110\&nbsp;cm notch, but this is not the case for the -70 cm shoreline.\&nbsp;On the east coast of Fiscardo Peninsula impacts of ancient earthquakes have left\&nbsp;some marks ({\textpm}6 cm) of emergence at about +15 and +40 cm, and of submergence at\&nbsp;about -20 (modern) -35, -50, -60, -70, -80, -90, -100 and -230 cm, with even some\&nbsp;evidence of past uplift and subsidence at the same sites.</div>},
