Seismic waves, also called Earthquake Waves, are energy waves generated by the sudden release of energy during an earthquake, volcanic activity, or explosion. They travel through the Earth\u2019s layers, providing vital information about its internal structure. The study of seismic waves forms the foundation of seismology, which helps in understanding earthquakes, predicting hazards, and investigating the Earth\u2019s crust, mantle, and core composition.<\/span><\/p>\n

Seismic Waves<\/b><\/h2>\n

Seismic waves can be broadly classified into body waves and surface waves, depending on how they travel through the Earth. They are recorded using instruments called seismographs, which measure ground motion. These records, known as seismograms, help geologists locate the epicenter, determine the magnitude, and study the internal structure of the Earth through the analysis of wave speed and path variation.<\/span><\/p>\n

Seismic Waves Classification<\/b><\/h2>\n

Seismic waves are categorized into two main types: Body Waves and Surface Waves, based on their mode of propagation through the Earth.<\/span><\/p>\n

1. Body Waves<\/b><\/h3>\n

Body waves move through the interior of the Earth and are further divided into Primary (P) waves and Secondary (S) waves.<\/span><\/p>\n
