“…In this scenario, EWS relevant to displacement monitoring usually consist of three levels of attention (Intrieri et al, 2013): (i) an ordinary level, when displacements are below predefined thresholds, (ii) a pre-alarm level, used when the landslide shows displacements above the seasonal oscillation, and (iii) an alarm level, which identifies a critical activation of the unstable area. The application of complex monitoring networks to large landslides is documented in several reference papers (Brückl et al, 2013;Lu et al, 2014;Malet et al, 2002;Tarchi et al, 2003). However, strategies for the use and dissemination of such monitoring results, especially in emergency scenarios, are yet lacking in standards and best practices.…”
