Using a nearly 200-year record of lava chemistry from Kīlauea and Maunaloa, Earth scientists from the University of Hawai’i at Mānoa and colleagues revealed that Hawai’i’s two most active volcanoes share a source of magma within the Hawaiian plume. Their discovery was published recently in the Journal of Petrology.
