How Mantle Hydration Changes over the Lifetime of a Subduction Zone
Water released from subducting oceanic plates influences the formation of volcanoes and earthquakes on Earth’s surface. A new study simulates how slab dehydration and mantle hydration levels change over time.

Earth’s Subduction May Have Been Triggered by the Same Event That Formed the Moon
The giant impact that formed the Moon may also have led to extrastrong mantle plumes that enabled the first subduction event, kick-starting Earth’s unique system of sliding plates.
