Bathymetric map of recent Hawaiian volcanism, highlighting the Loa and Kea tracks. Solid lines represent the geochemically distinct Loa (blue) and Kea (red) volcanic trends. The dashed lines are an estimate of the future projection of these trends based on the team’s hypothesis. Before the emergence of the Loa and Kea tracks, Kea-type lavas were overlain by Loa-type lavas at Ko’olau and Kaua’i. The encircled number indicates the approximate age at which Loa trend lavas first appeared at Ko’olau. Image credit: Jones et al, doi: 10.1038/nature22054.
