Two Harvard seismologists, Miaki Ishii and Adam Dziewonski, first proposed the idea of the innermost inner core in 2002 based on peculiarities in the speed of seismic waves passing through the ...

ULVZs, which are located in the lower mantle near the core-mantle boundary, can slow seismic waves by up to 50%. That's remarkable, said Michael Thorne , a geologist and geophysicist at the ...

By measuring the different speeds at which these waves penetrate and pass through the Earth's inner core, the researchers believe they've documented evidence of a distinct layer inside Earth known ...

Seismic waves have been observed traveling through the core of Mars for the first time, revealing details of the composition of the Red Planet's heart. The results may suggest why Earth can ...

Canberra, About 2,890 kilometres beneath our feet lies a gigantic ball of liquid metal: our planet’s core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound ...

Samuel’s team found that the seismic waves that had traveled through the planet could not be explained by a heterogeneous mantle, which would have made for a much slower wave velocity.

ULVZs, which are located in the lower mantle near the core-mantle boundary, can slow seismic waves by up to 50%. That's remarkable, said Michael Thorne , a geologist and geophysicist at the ...

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).
