“…Among the most characteristic aspects of the evolution of Tenerife, as it happens on other volcanic ocean islands, is the existence of constructive (accumulation of volcanic materials) and destructive episodes (caldera collapses, sector collapses , and erosion). Caldera collapses and sector collapses involve mass movements of tens to hundreds of cubic kilometres (e.g., Martí et al, 1994;Brown et al, 2003;Martí et al, 2010;Edgar et al, 2007Edgar et al, , 2017Carracedo, 1994;Masson, 1995, 2001;Ablay and Hurlimann, 2000;Hurlimann et al, 2004;Hunt et al, 2011Hunt et al, , 2013aHunt et al, , 2013b .
