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

Preliminary results of an investigation of crustal structure in Southeastern Europe

Abstract Travel-time curves for the most prominent phases of the longitudinal and shear waves for epicentral distances between zero and 140 km and between 200 km and 1000 km have been constructed for Southeastern Europe. Both refraction and reflection methods indicate a three-layered crust. The average thickness is approximately 16 km for the top layer, 15 for the middle layer and 11 for the lower layer. The crustal thickness varies from about 47 to 32 km from place to place. The extremely low value 0.21 for Poisson's ratio was found in the top as well as in the middle layer.</jats:p
