&lt;br /&gt;
===About Seismic Waves===&lt;br /&gt;
: '''Seismic waves''' travel through the [[Earth]].&lt;br /&gt;
: '''Seismic waves''' can be used to identify structures inside the [[Earth]] as the [[wave]]s can be [[reflect]]ed, [[refract]]ed or [[Absorb (Physics)|absorbed]] by different [[material]]s under the surface of the [[Earth]].&lt;br /&gt;
There are two types of '''seismic waves''':&lt;br /&gt;
*[[P-wave]]s - Known as [[P-wave|primary waves]] which are [[longitudinal]] [[wave]]s of [[Compression Wave|compression]] through the ground during an [[earthquake]]. &lt;br /&gt;
*[[S-wave]]s - Known as [[S-wave|secondary waves]] which are [[transverse]] [[wave]]s which cause the ground to shake from side to side during an [[earthquake]].&lt;/div&gt;</summary>
