Two arrows point away from the center showing tectonic plate divergence (North American Plate to the left, Eurasian Plate to the right). Below the island, a wide vertical column of hot rising mantle (red plume) reaching from deep mantle to the surface. Label 'Rift central', 'Panache mantellique', 'Basse vitesse sismique (onde S)', and 'Anomalie de Bouguer négative'. Professional geology textbook style, clear labels in French." } See more
