Similarly, seismic waves bend and speed up as they travel through denser layers of a planet’s interior. So instead of moving in a straight line through the crust, which is less dense ...

9. Explain to students that seismic waves travel fast, on the order of kilometers per second. The speed of a seismic wave depends on many factors. Ask students to think about a few factors that ...

A recent seismic analysis of NASA’s InSight mission data suggests that liquid water could still exist beneath the surface of ...

Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust ...

Seismic data from NASA’s InSight lander suggests liquid water may exist beneath Mars’ surface, supporting the potential for ...

Explore how North America is changing as its deep cratonic root thins and pieces are dripping into the Earth's mantle.

Two Japanese seismic researchers have shared their respective analysis on last week's powerful earthquake that struck near ...

There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their relative speed is faster than other waves. P waves can travel through ...

SEIS was the first ever seismometer to operate on Mars, and it was sensitive to three different types of seismic wave emanating from marsquakes. These were: P-waves, which oscillate back and forth ...
