Effects of basal drag on subduction dynamics from 2D numerical models

Suchoy, Lior; Goes, Saskia; Maunder, Benjamin; Garel, Fanny; Davies, D. Rhodri


Subducting slabs are an important driver of plate motions, yet the relative importance of different forces in governing subduction motions and styles remains incompletely understood. Basal drag has been proposed to be a minor contributor to subduction forcing because of the lack of correlation between plate size and velocity in observed and reconstructed plate motions. Furthermore, in single subduction system models, low basal drag leads to subduction behaviour most consistent with the...[Show more]
