What is a Seismic Wave?

What happens if you disturb the water of a calm pond?
Yes exactly!

When you disturb the water, it will continuously produce ripples or waves.
Just like in an earthquake, the sudden movement of the underground rocks produces energy waves that moves the Earth’s surface.

These waves are called Seismic Waves. These waves could travel through and on the surface that cause the shaking and vibrations of the ground.

There are 2 types of Seismic waves: Body waves and Surface Waves.

Basically body waves are waves that travel through the Earth’s inner layer. And while Surface waves are waves that can ONLY travel through the surface layer, making the Body waves travel faster than the surface waves. However, surface waves causes more damage than the body waves.

Now there are 2 types of body waves.
The Primary Waves and the Secondary Waves.

P- primary waves - fastest kind of waves it can move through solid rocks and liquids layers of the earth. Push and pull of the earth movement surface

Secondary waves- slower than p waves it only travels throug.solid rocks and cannot travel to liquid layer of the earth. Sway movement

Hypocenter of earthquake emits not only acoustic P-waves and S-waves, but also generate changes in local electromagnetic fields and could produce standing acoustic waves . Speed of P-waves, that are longitudinal, is about 4.5 times higher than S-waves, that are traverse. Speed of electromagnetic waves, that also could be of 3 types: longitudinal, traverse and standing, is 1 million times faster than speed of S-waves. Hypocenter emits them not only during but prior earthquake.as well.
