2010  Kap Verde Ilha do Fogo Panoramen  Chã das Caldeiras Pico Perqueno  Pico do Fogo  HOME The island of Fogo consists of a single massive stratovolcano that is the  most prominent of the Cape Verde Islands. The roughly circular 25-km-  wide island is truncated by a large 9-km-wide caldera that is breached to  the east and has a headwall 1 km high. The caldera (Chã das Caldeiras) is  located asymmetrically NE of the center of the island and was formed as a  result of massive lateral collapse of the ancestral Monte Armarelo edifice.  A very youthful steep-sided central cone, Pico, rises more than 1 km above  the caldera floor to about 100 m above the caldera rim, forming the 2829  m high point of the island. Pico, which is capped by a 500-m-wide, 150-m-  deep summit crater, was apparently in almost continuous activity from the  time of Portuguese settlement in 1500 AD until around 1760. Later  historical lava flows, some from vents on the caldera floor, reached the  eastern coast below the breached caldera. The last eruption on 2 April  1995, formed a small tributary volcano (Pico Pequeno 1,950 m) at the  western foot of the Pico, the lava flow limited to the interior of the Caldera.  Two small villages, called Portela and Bangaeira in the plain Chã das  Caldeiras, exists within the caldera of the volcano. After the outbreak of the  Pico Pequeno large parts of the cultural landscape were destroyed in the  Caldeira, the 2000 residents were temporarily evacuated.
