...; Christian Timm; Ian J. Graham; Ian C. Wright Abstract The Monowai volcanic center is located at the midpoint along the ∼2,530-km-long Tonga-Kermadec arc system. The Monowai volcanic center is comprised of a large elongate caldera (Monowai caldera area ∼35 km 2 ; depth to caldera floor 1,590 m), which has...

... at Monowai, another persistently active submarine volcano in the Kermadec volcanic arc. Repeated mapping there documented two major landslides over a 9 yr period ( Chadwick et al., 2008b ; Wright et al., 2008 ). The thicknesses and volumes of the landslides at Monowai (48–70 m and 40–85 × 10 6 m 3...

... budget of fast- and intermediate-rate spreading centers. The sizes of the volcanoes range from a few kilometers across to larger edifices up to 10s of kilometers in diameter and are most abundant within 5 to 10 km of the ridges. The off-axis volcanism is caused by hybrid magma plumbing systems...

... of ~1,500 to 2,000 m. The deepest hydrothermal systems occur along mature back-arc spreading centers distal to volcanic arcs where water depths range from ~2,000 to 3,700 m. These deeper vent sites probably represent the best modern analogues of ophiolite-hosted massive sulfide deposits. Boiling...

... volcanic centers between Brothers in the southern Kermadec arc, to Monowai in the northern Kermadec arc ( Fig. 1 ). Kermadec arc volcanoes sit on basaltic oceanic crust behind the Kermadec Ridge (the exceptions being Raoul and Macauley and Curtis Islands which sit on the Kermadec Ridge itself), thus...
