Earth Science
Scientists have documented that Earth's most colossal volcanic event—which created the Ontong Java Plateau more than 100 million years ago—dramatically transformed the oceanic plate beneath it. Seismic waves have revealed a complex structure of horizontal layers cut through by vast swarms of vertical dike formations, demonstrating the scale of ancient volcanic activity.
