Figure 6. Seafloor geology of the Eastern Manus Basin. Edifices of the Eastern Manus Volcanic Zone, which extends between the active ends of the Djaul and Weitin transform faults, range from picritic basalt to rhyodacite in composition. Red dots = known hydrothermal sites, including the three main active sites of PACMANUS, Deep Sea Monitoring System (DESMOS), and Susu Knolls. Red lines = extensional fault scarps.
