A reflection observed on multi-channel seismic profiles along and across the East Pacific Rise between 8??50??? N and 13??30??? N is interpreted to arise from the top of a crustal magma chamber located 1.2-2.4 km below the sea floor. The magma chamber is quite narrow (<4 - 6 km wide), but can be traced as a nearly continuous feature for tens of kilometres along the rise axis. ?? 1987 Nature Publishing Group.
