Modeling plume‐ridge interaction at a hotspot

Editor’s Highlight—


This study uses 3‐D models of viscous flow to understand the history of volcanism and plume‐ridge interaction related to the Réunion hotspot. The authors incorporate complex geometry and time-evolving boundary conditions to drive flow, while taking into account background mantle flow and dehydration stiffening. The results are useful for constraining the origin of the gap between Maldives and Chagos, and to explain the formation of the Rodrigues Ridge. There are also valuable findings about the interaction between the Réunion plume and the Central Indian Ridge. Overall, this modeling study presents a convincing demonstration that plume dynamics can explain observable details of the Réunion plume.
