Illustration of Earth's interior. Seismologists may have determined the origin of a strange type of seismic wave. Michael Thorne, University of Utah ...

Earthquakes, volcanic eruptions, shifting tectonic plates—these are all signs that our planet is alive. But what is revealed deep inside Earth surprises laymen and scientists alike: Almost 3000 ...

A Revolutionary Way to Study Earth’s Core. Seismic waves, traditionally generated by earthquakes, can now be detected from the movement of ocean waters caused by intense storms.The recent ...

Two Australian scientists argue in a new paper that within the Earth’s core, based on measurements of waves reverberating along the Earth’s diameter, is an innermost inner core, about 800 ...

When seismic waves encounter unusual structures in the mantle, changes in wave speed provide seismologists with clues about Earth’s deep interior. Over the decades, seismic data revealed that ...

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...

ULVZs, which are located in the lower mantle near the core-mantle boundary, can slow seismic waves by up to 50%. ... which poke into Earth's interior like stirring sticks into a smoothie.

They have demonstrated why earthquake waves change abruptly at a depth of 2,700 kilometres at the so-called D‘’ layer. The reason for this is a type of solid rock that nevertheless flows. This mineral ...
