Hawaiian plume motion through geological time

The video, created by Rakib Hassan, shows the southward motion of the modelled Hawaiian plume over geological time and the evolution of its tilt. Note the fast southward motion of the plume before 50 Ma, driven by the southward motion of its root at the northern edge of the Pacific Large Low-Shear Velocity Province (LLSVP). This motion came to a halt after 50 Ma. The black contour marks the 75% chemical concentration isosurface 100 km above the core mantle boundary.
