Earth's Biggest Volcanic Event Reshaped Plate
Seismic waves have dramatically revealed that Earth's largest volcanic event over 100 million years ago profoundly transformed the oceanic plate beneath the Ontong Java Plateau, creating a complex structure of horizontal layers and vertical magma channels. This groundbreaking discovery, indicated by unusually slow seismic waves suggesting chemical alteration, significantly enhances our understanding of how massive volcanic activity can physically and chemically modify oceanic plates.
