Tell students that a seismic reflection happens when a wave impinges on a change in rock type. Part of the energy carried by the wave is transmitted through the material (refracted wave ...

Since then, techniques for processing seismic reflection data have advanced considerably, enabling today's scientists to extract far more detailed images of subsurface features from existing datasets.

Like a moth in a cocoon, the metamorphosis of Earth's crust from molten goop to solid land is hidden from view, leaving ...

A seismic survey challenges the long-standing belief that only active volcanoes have large magma bodies sitting beneath them.
