Ocean waves are carried by water, sound waves are carried by air, and the seismic wa Seismic design is a critical aspect of building construction, especially in areas prone to earthquakes. Water waves, sound waves and seismic waves are common examples of this type. Light waves on the electromagnetic spectrum include those that are visible as well as those that are invisible to the human eye. (Note: Do not confuse seismograph with seismogram. Slide Prese LECTURE NOTES: *Seismic Waves-When an earthquake occurs, the shockwaves of released energy that shake the Earth and temporarily turn soft deposits, such as clay, into jelly (liquefaction) are called seismic waves, from the Greek seismo meaning earthquake. Body waves can travel through the Earth's layers, while surface waves (Rayleigh and Love Waves) can only move along the Earth’s surface. See examples of SEISMIC WAVES used in a sentence. ) Katie Atkinson 5 d’Alembert’s solution.
