WebJun 10, 2024 · The world’s deepest earthquakes happen in subduction zone areas as tectonic plates scrape against each other – and the Ring of Fire has the world’s biggest concentration of subduction zones. As energy is released from the earth’s molten core, it forces tectonic plates to move and they crash up against each other, causing friction. WebSeismic studies: More proof for sea floor spreading comes from seismic studies indicating that earthquakes occur along the rift valley of a midoceanic ridge and the cross‐cutting fractures that offset it. Rift valley earthquakes occur only along transform faults, those portions of the fracture zone located between the offset sections of a ...
