... appropriate remedial measures. The slope under examination consists of Cretaceous formations, mainly sandstones and marls, laying on highly fissured clay shales, dislocated and disarranged by an intense tectonic activity. Monitoring reveals that slow movements are developing along different shear surfaces at...

Resistivity analysis shows that the unstable soil layer has resistivity between 23 25 W m, the interlayer of clay, silt and sandstone have resistivity between 7 17 W m, claystone between 2 7 W m, and andesitic rock, as a sill, is between 40 85 W m. The rock analysis observed from shallow...

... molasse is formed by the Alpine forma- tions of the Western Thessaly Unit (Papanikolaou & Sideris, 1977, Lekkas, 1988). In the vicinity of Kanalia, it is the molassic formations that dominate (Figure 3). These are: Sandstones (mainly) and conglomerates (secondarily) at the central and northern part of...
