Geoscientists Finally Solve Mystery of Hawaiian Volcanoes

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.

Map of the United States (including Alaska, Hawaii and Puerto Rico), showing the mean annual temperature and the magnitude of the β coefficients from the obesity-adjusted meta-regression analysis, per state or territory over the period 1996–2009. The β coefficient from meta-regression analysis, representing the difference in diabetes incidence rate per 1 degree Celsius increase in temperature; red circles indicate a positive β coefficient, while blue circles indicate a negative β coefficient.
