Volcanostratigraphic profiles for the Azores region

Risk Analysis Management of Volcanic Slopes in São Miguel Island, Azores

“…Azores islands present different geological characteristics due to the volcanic nature of the rocks and the variability of its sequences of stratigraphic (Forjaz et al 2001;Malheiro and Nunes 2007;Malheiro et al 2018). A geomechanical classification was proposed for the different geological formations as represented in Table 1.…”

“…According to Malheiro and Nunes (2007), the general stratigraphy of Azores islands can be represented by five profiles that include the majority of situations found in this archipelago (Fig. 2).…”

“…In the case of Azores archipelago, localized in Atlantic Ocean and composed by nine islands of volcanic origin, the region has specific characteristics in what concerns the nature of the rock volcanic formations and is affected by several geohazard and natural disasters, including earthquakes, volcanic eruptions and also extreme meteorological events (Gaspar et al 2007;Malheiro and Nunes 2007;Malheiro et al 2018). Azores are situated in an area where the American, Eurasian and African plates meet together, with the existence of relevant fault systems (Fig.…”
