Climate change influences
magmatic production, in particular via the effects on erosion and hydrology, which modify the pressure exerted at Earth's surface on the
deep layers.
The images show that the axial valley at 4,000 m water depth is blanketed by an extensive set of pyroclastic deposits, raising important questions regarding the accumulation and discharge of
magmatic volatiles on such ridges and demonstrating that large - scale pyroclastic activity is possible along even the
deepest portions of the global mid-ocean ridge volcanic system.
