Resumo


​Terceira Island has three active volcanic systems, including two central volcanoes and a fissure zone. Terceira's eruptive history over the past 23,000 years has been marked by explosive eruptions of trachytic nature and extrusion of trachytic lavas, as well as basaltic eruptions of low explosivity and hydromagmatic eruptions. This diversity of eruptive styles demonstrates that the island is exposed to a wide range of volcanic hazards. To assess the susceptibility of the island to these hazards, the recent eruptive history of Terceira was analyzed, and these data was used to perform simulations to determine the areas potentially affected by future eruptions.​
