Stress transition from horizontal to vertical forces during subduction initiation
Subduction zones are fundamental to plate tectonics, yet how they initiate remains
enigmatic. Geodynamic models suggest that if horizontal forces dominate, the upper plate …

A Bayesian 3-D linear gravity inversion for complex density distributions: application to the Puysegur subduction system
We have developed a linear 3-D gravity inversion method capable of modelling complex
geological regions such as subduction margins. Our procedure inverts satellite gravity to …

A simple force balance model of subduction initiation
Y Li, M Gurnis - Geophysical Journal International, 2023 - academic.oup.com
The initiation and development of subduction zones are associated with substantial stress
changes both within plates and at plate boundaries. We formulate a simple analytical model …

Strike‐slip enables subduction initiation beneath a failed rift: New seismic constraints from Puysegur Margin, New Zealand
Subduction initiation often takes advantage of previously weakened lithosphere and may
preferentially nucleate along pre‐existing plate boundaries. To evaluate how past tectonic …
