Future supercontinent assembled in the northern hemisphere

Continental masses were amalgamated, broken apart and reassembled within supercontinents during different times in Earth history. Here, we attempt to predict the configuration of a potential future supercontinent based on a numerical simulation model of mantle convection. The mantle convection in our model is driven by a density anomaly compiled from a global seismic tomography model. The temporal evolution of a highly viscous continent with an initial present-day configuration is simulated for over 250 Ma. The result reveals that Australia, Eurasia, North America and Africa would gather in the northern hemisphere to form the future supercontinent. On the other hand, Antarctica and South America remain in the present-day position even after 250 Ma from present, and do not join the future supercontinent amalgam. The configuration of the future supercontinent numerically simulated herein is broadly consistent with the hypothetical model of the future supercontinent Amasia speculated from geological correlations.
