Cape Verde is a volcanic hotspot located in the Macaronesia ecoregion of the North Atlantic Ocean, approximately 375 miles (604 km) off the coast of West Africa. This volcanic archipelago is composed of ten islands (of which nine are inhabited) and eight islets. Holocen volcanism is mainly located at the islands of Sao Vicente, Brava and Fogo (Simkin and Siebert, 1994). Historical volcanic activity has been only recorded at the island of Fogo which consists of a single massive stratovolcano that is the most prominent of the Cape Verde Islands. The roughly circular 25-kilometer-wide island is truncated by a large 9-kilometer-wide caldera that is located asymmetrically NE of the center of the island and is breached to the east. A steep-sided central cone, Pico do Fogo, rises more than 1 kilometer above the caldera floor to about 100-meters above the caldera rim, forming the 2,829-meters-high point of the island. Pico do Fogo, which is capped by a 500-m-wide, 150-meters-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. The most recent eruption on the caldera floor took place en 1995. The Observatório Vulcanológico de Cabo Verde (OVCV) has been recently established as a joint effort of the Laboratorio de Engenharia Civil (LEC), the Serviço Nacional de Protecção Civil (SNPC) and the Universidade de Cabo Verde (UNICV) for reducing volcanic risk in the Cape Verde Islands.

Volcano  Monitoring Program

Permanent instrumental network

Due to increased awareness of volcanic hazard in Fogo Island following the 1995 eruption, it was installed a permanent instrumental network for the volcanic surveillance (Project VIGIL) in Cape Verde thanks to the PortugueseAID Agency.  This permanent instrumental network is located in Fogo and Brava islands and consist of (1) two broadband triaxial seismic stations (CMG-40T) at FPPC and BCCH observation sites, (2) five short-period triaxial seismic stations at FMLN, FPVC, FCVT, FBAL, and FMVE observation sites, (3) four bi-axial tilt stations (AGI701) at FMLN, FPPC, FLAN and FMVE observation sites. The network was complemented by an automatic meteorological STATION. A telemetry infrastructure based on spread-spectrum radio-links with three separate repeaters was installed to transmit the data in real-time over a distance of V100 km to LEC in the capital, Praia, Santiago Island (Fonseca et al., 2003).

Volcanic Alert System

The Serviço Nacional de Protecção Civil (SNPC) is in-charge for the communication of the volcanic alerts in Cape Verde after being provided by the Observatório Vulcanológico de Cabo Verde (OVCV). The volcanic alert system consists of a three colour alert levels: green, yellow and red.
