| Summary: | Conducting long-term hazard assessment in active volcanic areas is of primary
importance for land-use planning and defining emergency plans able to be
applied in case of a crisis. A definition of scenario hazard maps helps to
mitigate the consequences of future eruptions by anticipating the events that
may occur. Lanzarote is an active volcanic island that has hosted the largest
(> 1.5 km<sup>3</sup> DRE) and longest (6 years) eruption, the Timanfaya eruption
(1730–1736), on the Canary Islands in historical times (last 600 years).
This eruption brought severe economic losses and forced local people to
migrate. In spite of all these facts, no comprehensive hazard assessment or
hazard maps have been developed for the island. In this work, we present an
integrated long-term volcanic hazard evaluation using a systematic
methodology that includes spatial analysis and simulations of the most
probable eruptive scenarios. |
