Abstract:

Extensive ground fissures frequently occur within the eastern Thessaly basin, in central Greece and have been since 1989. This paper aims to give a preliminary explanation for their generation reasons by interpreting the results of a dense geophysical survey along the basin. This is combined with drilling data, as well as field work tectonic measurements, morphotectonic analysis and remote sensing data interpretation throughout the marginal areas of the basin. The gathering, homogenisation and organisation of different types of geo-data by using various GIS software packages led to the discovery of the alpine basement surface, which is covered by recent sediments, and possible structures that contributed to the development of the basin. The methodology of producing a 3D basement surface model and various lithology profiles across the basin, along with sediment isopach maps by combining surface with subsurface data, is described in this paper.
