Seismic anisotropy indicates organized melt beneath the Mid-Atlantic Ridge aids seafloor spreading

JM Kendall, D Schlaphorst, CA Rychert… - …, 2023 - pubs.geoscienceworld.org
Lithospheric plates diverge at mid-ocean ridges and asthenospheric mantle material rises in
response. The rising material decompresses, which can result in partial melting, potentially …

Shear-wave velocity structure of the Blanco oceanic transform fault zone

NI Adimah, YJ Tan, JB Russell - Geophysical Journal …, 2024 - academic.oup.com
Oceanic transform faults (OTFs) facilitate hydrothermal circulation which can modify the fault
zone materials and affect their rheological evolution. However, the depth extent and …

Genesis and Propagation of Low‐Frequency Abyssal T‐Waves

Z Shen, W Wu, J Callies - Journal of Geophysical Research …, 2024 - Wiley Online Library
Abyssal T‐waves are seismo‐acoustic waves originating from abyssal oceans. Unlike

SMatStack to enhance noisy teleseismic seismic phases: Validation and application to resolving depths of oceanic transform earthquakes

H Fang, RE Abercrombie - Geochemistry, Geophysics …, 2023 - Wiley Online Library
The depths of most moderate‐sized oceanic earthquakes are poorly constrained because of
the lack of local recording stations and noisy teleseismic recordings. This hampers our …

Broad fault zones enable deep fluid transport and limit earthquake magnitudes

K Leptokaropoulos, CA Rychert, N Harmon… - Nature …, 2023 - nature.com
Constraining the controlling factors of fault rupture is fundamentally important. Fluids
influence earthquake locations and magnitudes, although the exact pathways through the …

Major California faults are smooth across multiple scales at seismogenic depth

A Lomax, P Henry - Seismica, 2023 - hal.science
Surface traces of earthquake faults are complex and segmented on multiple scales. At
