Abstract Constraining the controlling factors of fault rupture is fundamentally important. Fluids influence earthquake locations and magnitudes, although the exact pathways through the lithosphere are not well-known. Ocean transform faults are ideal

The rupture area of the 2014 Iquique earthquake offshore northern Chile was spatially limited to a region where the plate boundary is non-reflective in seismic images, indicative of low fluid pressure. In contrast, north and updip of the rupture area

Applying seismic imaging methods on ocean bottom hydrophone data, the authors here describe a horizontal, flat lithosphere base plus lithosphere-asthenosphere boundary beneath the young (0.51 to 2.67 Ma) Juan de Fuca plate.

The Al-Idrissi Fault System in the Alboran Sea is a major tectonic structure in its initial stage. By using bathymetric and seismic reflection data, the authors unravel a 3D geometry for the AIFS, which corresponds to a crustal-scale boundary and pro

Plate tectonics describes oceanic transform faults as conservative strike-slip boundaries, where lithosphere is neither created nor destroyed. Seafloor accreted close to ridge-transform intersections (RTI) has therefore been expected to follow a simi

Gravity signals over the mid-ocean ridge-transform system reflect the distribution of underlying crustal and upper mantle mass anomalies. The gravity measurement, especially ‘residual’ gravity anomalies, relies on the gravitational corrections of

Plate tectonics defines oceanic transform faults as long-lived tectonics features. In the Pacific Ocean their traces, called fracture zones, can easily be identified as several thousands of kilometer-long features in bathymetric and gravity field dat

Our view on the structure of oceanic crust is largely based the interpretation of seismic refraction and wide-angle experiments, revealing that the upper basaltic crust (layer 2) is a region of strong velocity gradients. In contrast, the lower gabbro

Large igneous systems form either in areas of thin lithosphere at or near plate boundaries or by mantle-melting anomalies in intraplate settings with comparatively thicker lithosphere. Decompression melting or flux melt dominate at plate boundaries.

A founding ambition of scientific ocean drilling is to drill a MoHole that penetrates the entire ocean crust and into the upper mantle at a location representative of normal crustal accretion and evolution. This remains the only way to test many of o
