Seismic waves are generated by the sudden release of energy in the Earth's crust, typically from earthquakes or volcanic activity. These waves travel through the Earth, carrying information about the Earth's interior and helping scientists study its structure.

During an earthquake, seismic waves are released. These waves travel through the Earth and can be detected by seismographs. The main types of seismic waves are P-waves (primary waves), S-waves (secondary waves), and surface waves.
Waves are the carriers of both sound energy and seismic energy. In the case of sound energy, it is carried through compressional waves in the air or other mediums. For seismic energy, it is transmitted through elastic waves in the Earth's crust. In both cases, the energy is transferred through the vibration of particles.
seismic waves
Light waves are electromagnetic waves that can travel through a vacuum, while seismic waves are mechanical waves that require a medium, such as rocks or soil, to propagate. Light waves travel at the speed of light (about 300,000 km/s), while seismic waves travel at much slower speeds (a few km/s to several km/s). Light waves exhibit characteristics such as reflection and refraction, while seismic waves can produce earthquakes and reveal information about the Earth's interior.
Examples of longitudinal waves include sound waves, seismic waves, and sound waves in solids (such as ultrasound waves). These waves propagate by compressing and rarefying the medium in the direction of wave motion.
