WebApr 8, 2024 · Surface waves The waves that take place under the surface or through the earth are called body waves. On the other hand, the waves that occur on the surface of the earth are called surface waves. Body Waves or ‘Through The Earth’ Waves are Further divided into Two: P waves (for Primary waves) S waves (for Secondary Waves) WebThere are four basic types of seismic waves; two preliminary body waves that travel through the Earth and two that travel only at the surface (L waves). Combinations, reflections, and diffractions produce an infinity of other types, but body waves are the main interest in …
WebJul 27, 2024 · The energy from an earthquake travels through Earth in vibrations called seismic waves. Scientists can measure these seismic waves on instruments called seismometer. A seismometer detects seismic waves below the instrument and records them as a series of zig-zags. WebFeb 8, 2024 · Body and surface waves are the two groupings of seismic waves. Seismic waves are the waves that are generated by the release of energy at the epicenter of an earthquake. Body waves move through ...
