Seismic waves are energy waves produced by the sudden release of energy in the Earth’s crust, primarily during earthquakes. They are categorized into two main types: body waves, which include primary (P) waves and secondary (S) waves, and surface waves. P-waves travel faster and can move through solids and liquids, while S-waves are slower and […]
