Seismic wave

Seismic waves are waves that travel through or over Earth. They are usually generated by movements of the Earth's tectonic plates (earthquakes) but may also be caused by explosions, volcanoes and landslides. They can tell us much about the Earth's structure.

Find out about the various types of waves. What types of waves are sound, electromagnetic, brain, seismic, mechanical, and surface waves.

Earthquakes are natural phenomena caused by the sudden release of energy in the Earth's crust, resulting in seismic waves. This release of energy can occur due to tectonic plate movements, volcanic activity, or human-induced activities like mining. The severity of earthquakes is measured on the Richter scale or moment magnitude scale. They can lead to various effects, such as ground shaking, surface rupture, and sometimes tsunamis if they occur underwater. Preparedness and understanding…

1) Primary "P" body waves 2) Secondary "S" body waves 3) Surface waves 1) Primary ("P") waves -- - the fastest traveling wave through rock, so it's felt 1st after an earthquake - a type of body wave that pushes & pulls rock and liquid in the same direction as the wave moves 2) Secondary ("S") waves 2nd fastest moving, travels through solids only body wave that shifts rock side to side (at a right angle) relative to the direction of wave propagation: 3) Surface waves This group of waves is…

Seismic Wave: An energy wave caused by an earthquake.

A wave is a disturbance that transfers energy from one place to another in a regular and organized way. Among the most familiar waves are the surface waves that travel across…

The seismic waves released by submarine earthquakes have a lot of power to map temperature changes.

This isn't simple, but I'll give a beginners guide... Waves transfer energy from source to detector. They also tend to reflect at sudden changes in density. Waves that travel outwards (in 3D) from the epicentre of an earthquake (or more precisely the focus, as the epicentre is the point on the *surface * where waves first appear) can be reflected when they hit the interface between crust and mantle as they travel downwards, so return towards the surface and are detected there. Longitudinal…
