Shown above is the volcanic landscape of Ferraria, São Miguel Island, located in the Azores Island Chain of Portugal. São Miguel, the largest of the Azores islands, has also been the most volcanically active. In the past 500 years or so, five notable eruptions have occurred where lava flowed into the sea, altering the coastal topography. The last major explosive eruption on São Miguel likely occurred in 1630, but lava flows dominated by strombolian and Hawaiian-type eruptions have occurred since this time. Also, note the mudslides at bottom center. Photo taken on April 26, 2016.
