“…Fredrich and Wong, 1986;Wai et al, 1982). In the case of already damaged or fractured material, it has been shown that daily thermal cycling can induce shearing along existing fractures (Gunzburger et al, 2005) even in absence of freeze-thaw cycles. The most favorable periods are the ones corresponding to high thermal gradient in time (dT=dt) and in space (dT=dz, z representing the depth).…”

“…Gunzberger et al, 2005), microseismic cyclic 67 loading theoretically relies on an extremely high number of effective (damaging) load cycles 68 to exert any significant geomorphic consequence, since the damage increment resulting from 69 each loading cycle is likely to be exceedingly small, yet not cumulatively negligible ( resulting from, for example, time-dependent creep and fatigue processes driven by subcritical 209 crack growth (Rosser et al, 2007). In turn, this can cause stress redistribution and further 210 microcrack damage in a progressive failure process (Terzaghi, 1962;Bjerrum, 1967; 211 Eberhardt et al, 2004), causing the crack damage threshold, σ cd , to be exceeded, triggering a 212 transition from secondary to tertiary creep and, ultimately, rupture (Petley et al, 2005a, b).…”

“…These suggested mechanisms fail to describe time-dependent, thermally controlled sliding along discontinuities or opening of tensile fractures which may ultimately culminate in slope failure. Considering daily and seasonal temperature influences, several studies have evidenced extremely slow, creep-like, slope displacements due to cyclic temperature changes in long-term monitoring surveys (Vargas et al, 2013;Gisching et al, 2011;Mufundirwa et al, 2011;Gunzburger et al, 2005;Watson et al, 2004). Some of such studies were carried out for the preservation of cultural heritage sites around the world, for example in Slovakia (Vlcko et al, 2009), Japan (Greif et al, 2006) and Israel (Hatzor et al, 2002).…”
