Thermal response of jointed rock masses inferred from infrared thermographic surveying (Acuto test-site, Italy) [PDF]
, 2018 The Mediterranean region is affected by considerable daily and seasonal temperature variations due to intense solar radiation. In mid-seasons, thermal excursions can exceed tens of degrees thus influencing the long-term behaviour of jointed rock masses ...

Uncertainty in Rock Mass Jointing Characterisation [PDF]
Proceedings of the First Southern Hemisphere International Rock Mechanics Symposium, 2008 The analysis of jointing in a rock mass is a critical step in any rock engineering project as the extent of fracturing in the rock mass is the dominant factor controlling the rock mass strength. Uncertainties in the characterisation of a rock mass are very rarely considered.

Recorded displacements in a landslide slope due to regional and teleseismic earthquakes [PDF]
, 2015 Regional and teleseismic earthquakes can induce displacements along joints in a landslideinvolved rocky slope in Central Italy. The rarity of these effects is due to specific physical properties of the seismic signals associated with: (i) the energy ...
