Nobody knew what they are, and whether they are only a temporary phenomenon, or if they have been sitting there for millions ...

Determining Earth's structure is paramount to unravel its interior dynamics,' say the team in their paper, published in Scientific Reports. 'These findings suggest more diverse origins for these ...

The whole Earth oscillations, or tones, are mathematically described in such a way that we can easily "read" the damping (i.e. how loud the oscillation is) due to a specific structure and separate ...
