The Azores archipelago is located in the triple junction of the North American, Eurasian and Nubian tectonic plates. The origin of the magmatism in the archipelago remains controversial even though it has generally been associated with a mantle plume interacting with the local structural regime. Due to this peculiar geodynamic setting, earthquakes, subaerial and submarine volcanic eruptions may occur in the archipelago. The identification of possible signs of unrest of the volcanoes is challenging and much of the recent volcanic activity is characterized by the occurrence of seismic swarms, ground deformation episodes and the presence of secondary manifestations of volcanism. The archipelago is located in the vicinity of the central Northern Atlantic Ocean, what makes the islands vulnerable to storms, floods and landslides. The islands are thus ideally suited to apply different multidisciplinary methodologies for the study of geological hazards.
This session aims to focus on the Azores submarine plateau and islands as a natural laboratory for the study of different geological processes. Here, we aim at contributions from the different fields of Geology, Geophysics and Geochemistry dealing with the geodynamic context of the Azores, studying the evolution and geological diversity of the Azores and evaluate hazards that can affect the islands.
