Abstract. 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 (> 1.5km3 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.

Short summary
Lanzarote is an island (Canaries, Spain), that has hosted the largest and longest eruption in the archipelago (Timanfaya 1730–36). It brought severe economic losses and forced local people to migrate. We have developed the first comprehensive hazard assessment for the island. New eruptions will take place close to the last one and will be characterised by Strombolian activity, with ash emission towards the S, medium-length lava flows and hydromagmatic activity only close to the coastal areas.
