The general uplift rates for the Holocene are found to be about 1 0 1 4 mm yr depending on the sea level curve used for the elevation corrections This means that the kind of sea level curve used for such short time periods is of prime importance in the determination of vertical movement rates for a given area It should be noted that uplift rates show general trends when we deal with long periods of time As these periods become shorter it is possible to get faster or slower rates which reflect time intervals of different tectonic activity In areas of intense activity caused by a number of differential movements of faults like Perachora Peninsula and in times of fast sea level changes the correlation of these two factors becomes extremely complicated and even impossible as in the case of the notch and the consolidated beach material filling it at Flabouro The notch comprises an evolutionary signature during the Holocene Around 12 000 years ago when sea level was at about 50m below the present one the formation of the notch occurred
The height of the notch which is about 1 1m should have taken a few hundred years to form There followed a period of intense tectonic uplift which overcame the rising sea level indicated by the presence of the terrestrial reddish deposit Fig 8b Around 9 000 years ago sea level reached the notch again partly filled it and covered the terrestrial material
