Key Concepts

Seismic Waves

Seismic waves are energy waves that propagate through the Earth, generated by disturbances such as earthquakes. They provide crucial information about the interior structure of the planet and are categorized based on their speeds and movement patterns.

P Waves

P waves, or primary waves, are compressional waves that travel by alternating compression and expansion of the material in the direction of propagation. They are the fastest type of seismic wave and are typically the first to be recorded on seismographs during an earthquake.

S Waves

S waves, or secondary waves, move material perpendicular to the direction of wave propagation through shear motion. They travel slower than P waves and are unable to move through liquids, which makes them useful in studying the Earth's interior properties.
