Cascading Effects of Extreme Geohazards on Tenerife (Canary Islands)

Extreme geohazards (volcanic eruptions, earthquakes, landslides, and tsunamis) have the potential to inflict cascading effects whose associated risks are difficult predict prepare for. Thus, these events generally not taken into account in hazard assessment. Anticipating occurrence of such extreme is thus key if our life-styles remain safe sustainable. Volcanic islands often source complex successions disastrous events, as evident from any examination, for instance, geological record regions Hawaii, Canary Islands, Reunion Indonesia. The island Tenerife Archipelago an excellent example where hazards occurred several times past could occur again future. A sequence involving a caldera-forming eruption, high-magnitude seismicity, mega-landslides tsunamis at least twice during construction this island. In order understand possible consequences processes they were reoccur, we simulated extent impact multiple, geohazard episode similar last recorded one that took place on around 180 ka. implications succession analyzed local, regional global scales, results obtained discussed within framework disaster risk-reduction policies.
