Still photographs and video images collected along the Neovolcanic Zone of the East Pacific Rise from 10??15???N to 11??53???N show that recent volcanic sheet flows, possibly less than 100 years old, are superimposed on an older sediment-laden pillow terrane. This recent activity is restricted to a narrow zone that crosses two topographic highs at 10??55???N and 11??26???N and diminishes along-axis away from these highs. The association of recent sheet flows with older flows and collapse structures on the overlapping spreading centers at 11??45???N supports the evolutionary model for the occurrence and evolution of overlapping spreading centers by MacDonald and others (1986, 1988). ?? 1988 Springer-Verlag New York Inc.
