...; 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...

These embayments are separated by three topographically elevated volcanic rift zones ( Carracedo, 1994 ) defined by fissuring, faulting, and aligned eruptive centers, which continue offshore. The submarine extension of the southern ridge ( Fig. 1B ) consists of narrow...
