CAPE VERDE

Physical geography 2/2

Most recently erupting in 1995, Pico do Fogo is the largest active volcano in the region. It has a 8 km (5 mi) diameter caldera, whose rim is 1,600 m (5,249 ft) altitude and an interior cone that rises to 2,829 m (9,281 ft) above sea level. The caldera resulted from subsidence, following the partial evacuation (eruption) of the
magma chamber, along a cylindrical column from within magma chamber (at a depth of 8 km (5 mi)).

Extensive salt flats are found on Sal and Maio. On Santiago, Santo Antão, and São Nicolau, arid slopes give way in places to sugarcane fields or banana plantations spread along the base of towering mountains. Ocean cliffs have been formed by catastrophic debris avalanches.

According to the president of Nauru, Cape Verde has been ranked the eighth most endangered nation due to flooding from climate change. LINK
