WBocas de Fogo is a volcano near the community of Urzelina, Velas municipality, São Jorge Island, Azores. It erupted in May and June 1808, causing destruction and over 30 deaths in Urzelina and producing a basalt field of volcanic rock extending to the Ponta da Urzelina. The eruption was the last sub-aerial event observed in the Azores; most recent eruptions have occurred along submarine vents, with the Capelinhos eruption (1957–58) starting as a submarine eruption and the 1998–2001 Serreta eruption being exclusively submarine.
WThe Capelinhos is a monogenetic volcano located on the western coast of Faial Island in the Azores. It is part of the larger volcanic complex of Capelo, which includes 20 scoria cones and lava fields that are aligned west-northwest to east-southeast from the Cabeço Gordo caldera. Although the name "Capelinhos" is associated with the volcano, it technically refers to the western cape of the parish of Capelo. It can be considered the westernmost point of Europe; there are more westerly islands in the Azores archipelago but they lie on the North American Plate.
WDom João de Castro Bank is a large submarine volcano located in the central north Atlantic Ocean, between the islands of São Miguel and Terceira in the archipelago of the Azores.
WGruta das Torres, is a lava cave, a geological formation of volcanic origin formed from the flow and cooling of subterranean magma rivers. This formation is located outside the parish of Criação Velha, in the municipality of Madalena, on the western flanks of the island of Pico. The cave system formed from a series of pāhoehoe lava flows which originating from the Cabeço Bravo parasitic cone about 500 to 1500 years ago. The caves are a group of interconnected lava tubes between 0.5–22 metres (2–72 ft) width, created from both pāhoehoe and ʻaʻā types of lavas generated during different geological periods. It has a height between 1.1 and 15 metres (3.6–49 ft) and is located at an elevation of 300 metres (980 ft). With an estimated length of over 5.2 km (3.2 mi) it is the longest lava cave in the Azores. Access to the cave was managed by the Mountaineering Association. Starting in 2011, AZORINA, SA took over the management and organization of the cave.
WMadeira, officially the Autonomous Region of Madeira, is one of the two autonomous regions of Portugal. It is an archipelago situated in the North Atlantic Ocean, in a region known as Macaronesia, just under 400 kilometres (250 mi) to the north of the Canary Islands and 520 kilometres (320 mi) west of Morocco. Madeira is geologically located on the African Tectonic Plate, though the archipelago is culturally, economically and politically European. Its total population was estimated in 2016 at 289,000. The capital of Madeira is Funchal, which is located on the main island's south coast.
WThe Savage Islands or Selvagens Islands are a small Portuguese archipelago in the North Atlantic Ocean, 280 kilometres (175 mi) south of Madeira, and 165 kilometres (105 mi) north of the Canary Islands. The islands are also known in English as the Salvage Islands or Dry Salvages.
WVolcanic Complex of Topo is a complex of scoria cones and volcanic structures, located near the village Topo in the southeastern part of the island of São Jorge, in the Portuguese archipelago of the Azores.
