Abstract
Mount Cameroon erupted in October 1982 after a 23-yr period of quiescence. The eruption lasted for 24 days and produced 107 m3 of basanite lava from a fissure on the south-west flank. The lavas showed a steady variation in chemical composition with the first lavas slightly more evolved than the last. This chemical variation can be explained by mixing a reservoir magma very close in composition to the 1959 lava with new magma slightly more basic than the last 1982 lava. The size of the pre-inflation magma reservoir may be estimated from mass-balance calculations and must lie in the range 2.3×106–1.3×107 m3.
