There are two types of seismic waves, called P and S. As waves pass through the planet, they can move in different ways: With P waves, the material moves backward and forward in the same direction ...

When an earthquake occurs, different types of seismic waves radiate out from the epicenter. P waves are fast and weak, while S waves are slower and more destructive.

Seismic waves generated by quakes and a meteorite strike on Mars allowed NASA’s InSight lander to collect data that helped reveal secrets of the Martian interior.

A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. The researchers derived a new equation that ...

SWOT’s advanced Ka-band Radar Interferometer (KaRIn) uses two antennas, positioned on a 10-meter boom, to triangulate wave heights with unprecedented precision, mapping swaths of ocean up to 50 ...

Scientists observed seismic waves traveling through Mars' core for the first time and confirmed model predictions of the core's composition. An international research team—which included ...
