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.
Strictly speaking, a tidal wave is one caused by the movement of the tide, which in turn results from the imbalanced, extraterrestrial, gravitational influences of the moon, sun, and planets, whereas a tsunami is specifically generated by a violent, impulsive undersea disturbance or activity near the coast or in the ocean, such as an earthquake, landslide (both undersea and from land into water) or even an asteroid hitting the ocean.
