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.

Repeated Coseismic Uplift Above the Patton Bay Splay Fault, Alaska
Stratigraphic and diatom analyses suggest ruptures of the Patton Bay splay fault occurred together with half of the documented great Alaskan megathrust earthquakes during the past 4,200 years.
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.
Earthquakes Can Trigger Megathrust Slip in Cascadia
A 2022 earthquake in Northern California may have triggered slow slip in the Cascadia Subduction Zone, according to a new study.
Forecasting Earthquake Ruptures from Slow Slip Evolution
A new generation of physics-based models that integrate temporal slip evolution over decades to seconds opens new possibilities for understanding how large subduction zone earthquakes occur.
Uncovering Earthquake Evidence in Azerbaijan’s Greater Caucasus Mountains
A new study unearths geological evidence that corroborates historical accounts of large earthquakes along the Kura fold-thrust belt.
The Nature of Mantle Flow May Depend on the Type of Slab Subducting
Researchers tease apart the links between slabs and mantle flow near subduction zones, upending some traditional views of subduction-induced mantle flow.
Plate Boundaries May Experience Higher Temperature and Stress Than We Thought
Surface heat flux data shed light on conditions deep below Earth’s surface, at a tectonic plate interface where major earthquakes initiate.
Revolucionando la ciencia de los terremotos en Cascadia
Un nuevo centro reunirá a científicos de sismos para estudiar la zona de subducción de Cascadia y aclarar los peligros sísmicos.
Shaking Up Earthquake Science in Cascadia
A new center will bring together earthquake scientists to study the Cascadia Subduction Zone and clarify seismic hazards.
