Foreshock and aftershock sequences of the Cremasta earthquake and their relation to the waterloading of the Cremasta artificial lake

Investigation of the time and magnitude distributionof the fore- and aftershocks of the Cremasta lake earthquake which occurredon February 5, 1966 is made. The deformation characteristics andspatial distribution of these shocks is also studied. Strong evidence is presentedthat the foreshocks and the main shock have been triggered by thewaterloading of the Cremasta artificial lake

A note on the crustal structure of the eastern Mediterranean

A simple model is proposed for the mean crustal structureof the eastern Mediterranean. According to this model, which fits the available seismic data, the crust of the eastern Mediterranean consists of five layers of 21 km total thickness and the velocity of the longitudinal waves varies between 2.2 and (i.O km/sec in this crust
