The submarine Clark stratovolcano lies near the southern end of the Southern Kermadec arc. This basaltic and dacitic edifice consists of a basal substrate of massive lava flows, pillow lavas, and pillow tubes overlain by volcaniclastic sediments. Craters are present along the complex crest. Clark is the southernmost volcano of the submarine chain that displays hydrothermal activity. Diffuse hydrothermal venting and sulfide chimneys were observed near the summit during a New Zealand-American NOAA Vents Program expedition in 2006.
