Seismic waves are waves produced by earthquakes. This occurs when rocks under the earth suddenly break or explode. There are two MAIN TYPES of seismic waves called body waves and surface waves. Body waves have the capacity to travel through the Earth's inner layers. They have a higher frequency and they are the ones that first occur under water at the onset of an earthquake.
Because of the size of these plates, earthquake waves carry huge amounts of energy. In this lesson, we discussed four types of seismic waves: P-waves, S-waves, Rayleigh waves and Love waves. The first two are body waves, the latter two are surface waves. Love waves cause the most damage and P-waves the least. Thanks to our study of seismic waves, we have a better idea of what to expect when an earthquake hits. Through this knowledge and better preparation, we can save both property and human lives.
