P-waves, also known as primary waves or pressure waves, travel at the greatest velocity through the Earth. When they travel through air, they take the form of sound waves – they travel at the speed of sound (330 ms-1) through air but may travel at 5000 ms-1 in granite. Because of their speed, they are the first … Ver mais S-waves, also known as secondary waves, shear waves or shaking waves, are transverse waves that travel slower than P-waves. In this case, particle motion is perpendicular to the direction of wave propagation. Again, … Ver mais Surface waves are similar in nature to water waves and travel just under the Earth’s surface. They are typically generated when the source of the earthquake is close to the Earth’s surface.

WebS Waves, known as Secondary Waves, are seismic waves that simply go about in an S shape, form, and is the second wave to arrive during an earthquake. S waves cannot travel through liquids, they can travel through solids. P waves, known as Primary waves, are also part of a seismic wave. WebThese tiny microseisms can be caused by nearby activities, such as heavy traffic or wind, or by distant sources such as interactions of waves with the ocean floor. They may also be caused by earthquakes that are too small or too far away to be recognized as earthquakes.

A seismic wave is a wave of acoustic energy that travels through the Earth or another planetary body. It can result from an earthquake (or generally, a quake), volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low-frequency acoustic energy. Seismic waves are studied by seismologists, who record the waves using seismometers, hydrophones (in water), or accelerometers. Seismic waves are distinguished from seismic noise (…
