In 2021 and 2022, NASA’s InSight lander picked up the tremors coming from the depths of Mars. These Marsquakes were quickly ...

The diagrams show what happens when P waves and S waves pass through the Earth. S waves do not pass through the Earth's core S waves cannot pass through the liquid outer core, but P waves can.

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward ...

These waves are higher frequency than surface waves. P waves are also known as compressional waves, because they push and pull. Particles subjected to a P wave move in the same direction that the wave ...

using both P waves and S waves to explain how scientists calculate the epicentre of an earthquake. Use a glass bowl filled with tomato soup and cut outs of the continents to show how they would ...
