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 ...

Gigantic hidden fortresses discovered 1,800 miles underground in Earth's mantle, rewrite how the planet's interior works.

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

Probing Earth's interior with seismic waves. Earth's interior is layered like an onion. The solid iron-nickel inner core -- today 1,200 kilometers (745 miles) in radius, ...

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth’s inner core, according to seismologists from The Australian National University (ANU).

For the study, the researchers analyzed seismic wave data from earthquakes that traverse the interior of the Earth, get “spit out” on the opposite side of the planet, called the antipode, then return ...

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 ...

Powerful earthquakes, such as one that occurred in 2018 in Alaska, can send seismic waves reverberating through Earth’s center (illustrated). Such waves reveal an innermost layer to the inner ...
