Feature--Physical geology of the Fogo volcano (Cape Verde Islands) and its 2014-2015 eruption

摘要

The geological development of the Fogo island volcano commenced in the early Quaternary, and much later during the Last Glacial stage this involved a mega-scale lateral collapse of the former edifice. This later event created a large caldera-like landform open to the east, the floor of which is known as the Cha, and subsequently within this a strato-volcanic cone has grown. The last phase of volcanic activity started in late 2014 and persisted for 77 days.
