Full Waveform Inversion (FWI) is capable of finely characterizing the velocity structure, anisotropy, viscoelasticity, and attenuation properties of subsurface media, which provides critical ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...

The deep oceans are far from flat. They feature ridges, trenches, seamounts, and valleys, creating a diverse and dramatic ...

The mantle of the Earth, up to 1,800 miles (2,900 kms) thick and 84% of the Earth's volume, was assumed to be a simple ...

The Earth’s mantle, stretching up to 1,800 miles thick and making up a whopping 84% of the planet’s volume, used to be ...

Are subterranean lifeforms viable on Mars? A new interpretation of Martian seismic data by scientists Ikuo Katayama of Hiroshima University and Yuya Akamatsu of Research Institute for Marine ...

Researchers have found new evidence for a massive subsurface ocean on Mars, again raising the possibility of microbial life.

Two undiscovered mountains that are 100 times higher than Everest have been discovered by experts, changing the course of ...

Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground.

Researchers explore the likelihood that Earth's climate, as affected by solar heat, plays a role in seismic activity. Using mathematical and computational methods, they analyzed earthquake data ...

Seismologists have long known that seismic waves -- generated by earthquakes -- do not travel through all parts of Earth's interior at the same speed. This principle has allowed them to visualise ...
