..., analyses of slope evolution and fail- ure mechanisms are necessarily based on limited geological evidence and monitoring data, laboratory tests only on near-surface materials and schematic numerical models. This combined approach was ap- plied to the analysis of the sequence of slope failures that occurred...

... basin with a large sequence of extrusive rocks (basalt and tuff). Core analysis of the tuffaceous rock gave a porosity range of 5.6 to 21.7% (average 15.1%) and a permeability range of 0.03×10-3 to 27.4×10-3 m2 (average 1.17×10-3 m2). The reservoirs are of too low per- meability to be placed onto...
