Structure of the North‐Central Chile Subduction Zone From Local Earthquake Tomography
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract The fluid cycle in subduction zones prescribes large parts of its structure and seismogenic behavior. Background seismicity inside the downgoing slab is linked to fluid release from dehydration reactions, whereas fluid overpressure along the plate interface can alter interplate coupling, megathrust earthquakes, and the presence or absence of ...
