The volcano spewed large amounts of very fluid basaltic lava. An historian wrote in full detail about the eruption; it is included in the account called Fénix Angrense ("The Phoenix of Angra"). 1564: Another volcanic eruption on Lagoa do Fogo, São Miguel. The eruption began on 13 February and lasted for a few days, causing no damage.

Capelinhos Volcano, Faial Island, Azores, showing the lighthouse which marked the western coastal limit of Ponta dos Capelinhos. The Capelinhos eruption represented the first time that a submarine eruption was documented from beginning to end. Its location near an inhabited island with good communications meant it could be intensively studied.
Although there are no active volcanoes in the continental territory of Portugal, apart from geological remnants of ancient volcanism, the Portuguese Atlantic island possessions have a long history of active volcanism. The following is a list of active and extinct volcanoes in the Portuguese territories of the Azores and Madeira.
Mount Pico (Portuguese: Montanha do Pico) is a currently dormant stratovolcano located on Pico Island, in the mid-Atlantic archipelago of the Azores.It is the highest mountain in Portugal, at 2,351 metres (7,713 ft) above sea level, and is one of the highest Atlantic mountains; it is more than twice the elevation of any other peak in the Azores.
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 (that eventually grew into a sub-aerial event) and the 1998–2001 Serreta eruption being exclusively submarine (never breaking the surface).
The last significant volcanic eruption, the Capelinhos volcano (Vulcão dos Capelinhos), occurred off the coast of the island of Faial in 1957; the most recent volcanic activity occurred in the seamounts and submarine volcanoes off the coast of Serreta and in the Pico-São Jorge Channel.

The volcano was reduced by around 300 m (980 ft) in height due to an eruption that occurred around 1000 years ago. This was one of the last major explosive events recorded in the Azores. [4] [5] Although the central volcano has not been active within the past two centuries, it has seen activity related to the eruption of Capelinhos (1957–58 ...
