'Peak of Fire') is an active stratovolcano located on the island of Fogo, Cape Verde, rising to 2,829 metres (9,281 ft) above sea level.

The caldera is bounded by steep near-vertical fault scarps on the north, west, and south sides but is breached to the east where lava can flow to the coast.

[7] North-northeast-trending eruptive fissures opened along the western flank of Pico, which formed inside the caldera between about 1500 and 1760.

The eastern side of Fogo collapsed into the ocean 73,000 years ago, creating a tsunami 170 meters high which struck the nearby island of Santiago.

These earthquakes increased in magnitude and frequency through April 2, and a particularly strong one was reported at about 8 p.m., four hours before the eruption apparently began.

The eruption began with Strombolian activity, quickly followed by a 'curtain-of-fire' lava fountain that fed a flow which cut off the road to the village of Portela by 2 a.m.

[5] During the day on April 3, the island was engulfed by a thick cloud of dark ash that reached 2.5 to 5 kilometers high.

On April 5, the new lava flow reached the western caldera wall and destroyed about five houses and the main water reservoir.

[5] On April 18, a portable seismometer began to record much stronger volcanic tremors that indicated a change in eruptive style from lava fountains back to Strombolian activity.

[11] The population of Chã das Caldeiras, totaling around 1,000 inhabitants, spent the night outside their homes due to the strong earthquakes,[10] and started being evacuated when the eruption began.

The village of Portela in the Chã das Caldeiras is now covered by a lava stream which has completely destroyed the housing stock.

[13] 75% of the buildings in Portela, Bangaeira and Ilhéu de Losna, sections of Chã das Caldeiras, had been destroyed.

[14] Pico do Fogo consists of basanite, tephrite, phonotephrite, clinopyroxene, amphibole, magnetite, olivine, melilite and leucite.
