P Earthquake Waves. P waves travel faster than S waves. P and S waves cause the rocking motion of the earth. Seismic waves may travel either along or near the earths surface Rayleigh and Love waves or through the earths interior P and S waves. It is like the ripples created in water if you throw a stone in it.
Recorded during a 2007 teacher workshop on earthquakes and tectonics. Demonstration of P and S waves properties using students to represent atoms in solids and liquids. When an earthquake occurs it releases waves of energy which are known as Seismic waves. An S wave is slower than a P wave and can only move through solid rock. This is the fastest kind of seismic wave and consequently the first to arrive at a seismic station. Humans can only feel the ramifications it has on the crust.
Not long ago Japan marked 10 years since the deadly 2011 earthquake and.
The P waves of the earthquake will arrive at the town first since they travel faster and the S waves will arrive a little later. Demonstration of P and S waves properties using students to represent atoms in solids and liquids. Adding reflections at the underside of Earths surface. The study of seismic waves provides a complete picture of the layered inter. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air and wreak destruction across entire cities. Body Waves S wave transverse wave The second type of body wave is the S wave or secondary wave which is the second wave you feel in an earthquake.
