Bocas de Fogo (Portuguese for mouths of fire) 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 (that eventually grew into a sub-aerial event) and the 1998-2001 Serreta eruption being exclusively submarine (never breaking the surface).
