Faial Island (pronounced [fɐjˈal]), also known as Fayal Island, is a Portuguese island contained within the Central Group or Grupo Central of the Azores, in the Atlantic Ocean.
The Capelinhos volcano is the westernmost point of the island and can be considered the westernmost point of Europe (from a geophysical perspective) other than the Monchique Islet.
The Azores, officially the Autonomous Region of the Azores, is an autonomous region of Portugal, in the Atlantic Ocean about 1,400 km (870 miles) west of mainland Portugal. Together with Madeira, it is one of the two autonomous regions of Portugal and a special territory of the European Union. It is the westernmost point and region of Portugal.
The Azores is an archipelago composed of nine volcanic islands in the Macaronesia region of the North Atlantic Ocean.There are nine major Azorean islands and an islet cluster, in three main groups. These are Flores and Corvo to the west; Graciosa, Terceira, São Jorge, Pico, and Faial in the centre; and São Miguel, Santa Maria, and the Formigas islets to the east. They extend for more than 600 km (370 mi) and lie in a northwest–southeast direction. All the islands have volcanic origins, although some, such as Santa Maria, have had no recorded activity in the time since the islands were settled several centuries ago. Mount Pico on the island of Pico is the highest point in Portugal, at 2,351 m (7,713 ft). If measured from their base at the bottom of the ocean to their peaks, the Azores are among the tallest mountains on the planet. The Azores are located at the seismically active Azores triple junction plate boundary where the North American plate, Eurasian plate and Nubian plate meet.
A volcanic bomb or lava bomb is a mass of partially molten rock (tephra) larger than 64 mm (2.5 inches) in diameter, formed when a volcano ejects viscous fragments of lava during an eruption. Because volcanic bombs cool after they leave the volcano, they are extrusive igneous rocks. Volcanic bombs can be thrown many kilometres from an erupting vent, and often acquire aerodynamic shapes during their flight. Bombs can be extremely large; the 1935 eruption of Mount Asama in Japan expelled bombs measuring 5–6 m (16-20 ft) in diameter up to 600 m (2,000 ft) from the vent. Volcanic bombs are a significant volcanic hazard, and can cause severe injuries and death to people in an eruption zone. One such incident occurred at Galeras volcano in Colombia in 1993; six people near the summit were killed and several seriously injured by lava bombs when the volcano erupted unexpectedly. On July 16, 2018, 23 people were injured on a tour boat near the Kilauea volcano as a result of a basketball-sized lava bomb from the 2018 lower Puna eruption.
Volcanic bombs are known to occasionally explode from internal gas pressure as they cool, but in most cases, most of the damage they cause is from impact, or subsequent fire damage. Bomb explosions are most often observed in "bread-crust" type bombs.
São Jorge (Portuguese pronunciation: [sɐ̃w ˈʒɔɾʒɨ]; Portuguese for 'Saint George') is an island in the central group of the Azores archipelago and part of the autonomous region of Portugal. Separated from its nearest neighbours (Pico and Faial islands) by the 15-kilometre (9.3 mi) Pico-São Jorge Channel, the central group is often referred colloquially as part of the Triângulo ("Triangle") group or just "The Triangle". São Jorge is a relatively long thin island with tall cliffs, whose 8,381 inhabitants are concentrated on various geological debris fields (fajãs) along the north and south coasts; from east to west, the island is 53 kilometres (33 mi) long and, north to south, 8 kilometres (5.0 mi) wide: its area is 237.59 square kilometres (91.73 sq mi).
The Capelinhos (from Capelo + -inhos diminutive, which literally means "little cape") 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 Caldeira Volcano 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.
A volcanic eruption lasted for 13 months, from September 27, 1957 until October 24, 1958, which may have been two overlapping volcanic eruptions. While enlarging the land by 2.4 km, it spawned 300 seismic events, hurled ash 1 km, destroyed 300 houses in the parishes of Capelo and Praia do Norte and caused the evacuation of 2,000 people (emigration to the US and Canada). On October 25, the volcano entered a period of dormancy. It is a part of an active fissural volcanic complex which creates multiple seismic and volcanic events.
