What is the difference between P-waves and S-waves?

Back

P-waves (primary waves) are compressional waves that travel faster and can move through solids and liquids, while S-waves (secondary waves) are shear waves that only travel through solids.

Front

What is the Richter scale?

Back

A logarithmic scale used to measure the magnitude of an earthquake based on the amplitude of seismic waves.

Front
