Investigating the response of hydrothermal convection to decadal cycles of magmatic inflation at the East Pacific Rise, 9º50'N Open
Hydrothermal circulation at the axis of fast-spreading mid-ocean ridges is intrinsically linked to magmatic activity, which typically fluctuates on decadal time scales, i.e., the characteristic recurrence time of eruptions. While hydrother…

Deformation on Rainbow Massif, Mid‐Atlantic Ridge, Illuminated With Microearthquakes Detected by Machine Learning Open
Oceanic detachment fault systems are characteristic of slow‐spreading mid‐ocean ridges, where reduced magma supply leads to increased extension by faulting and exhumation of oceanic core complexes (OCCs). OCCs have complicated structure re…

Magma-induced tectonics at the East Pacific Rise 9°50’N: Evidence from high-resolution characterization of seafloor and subseafloor Open
At fast-spreading centers, faults develop within the axial summit trough (AST; 0 to 250 m around the axis) primarily by diking-induced deformation originating from the axial magma lens (AML). The formation of the prominent abyssal-hill-bou…
