Smithsonian Institution Bulletin of the Global Volcanism Network, v. 20, no. 11/12, November-December 1995 Fogo (Cape Verde) Eruption of 2 April through 28 May covered over 6 square kilometers of land Fogo SW Cape Verde Islands, Atlantic Ocean 14.95 N, 24.35 W; summit elev. 2,829 m The eruption that began on 2 April (Bulletin v. 20, nos. 4-5) ended on or about 28 May, according to V. Martins. New lava flows covered ~6.3 km^2 of land. The total volume of lava extruded was ~60-100 x 10^6 m^3, assuming lava flow thicknesses of ~9-15 m; the known range was from 1 to >20 m. Based on six major-element XRF analyses, the lava flow erupted during the first night (3 April) was determined to be a differentiated kaersutite-bearing phonotephrite (IUGS system), whereas later lava flows and spatter were more primitive tephrite basanite. Fogo Island consists of a single massive volcano with an 8-km-wide caldera breached to the E. The central cone was apparently almost continuously active from the time of Portuguese settlement in 1500 A.D. until around 1760. The June-August 1951 eruption from caldera vents S and NW of the central cone began with ejection of pyroclastic material.
