Santa Isabel
"Santa Isabel is the largest and highest of three coalescing basaltic shield volcanoes forming Bioko (Fernando Poo) Island. Lying on the continental shelf along the Cameroon Line, Santa Isabel is modified by the same NNE faults as Mt. Cameroon across the Gulf of Guinea on the African mainland. The 3007-m-high volcano contains numerous satellitic cinder cones. Santa Isabel is the only Bioko Island volcano with reported historical eruptions, although they are poorly documented. Three eruptions, during the late-19th and early-20th centuries, have been reported form SE flank vents."  -Smithsonian Volcano Archive
