Seismic anisotropy offers insight into viscous BLOBs at base of Earth's mantle

In some parts of Earth's interior, seismic waves travel at different speeds depending on the direction in which they are ...

Marsquakes indicate that the inner core of the red planet is solid, not liquid

An analysis of seismic waves propagating through Mars finds evidence that the planet has a small, solid inner core, which challenges existing planetary models. Read the paper: Seismic detection of a ...
