Amplitude is deviation of wave from zero crossing. Maximum positive amplitude is referred to peak and Maximum negative amplitude is referred to trough. The value of amplitude is equal to the value of seismic trace at specific depth. While, Seismic trace is parameter of seismic wave that represents contrast of acoustics impedance on the boundary of bedding rock on a geophone <ref>Abdullah, A. (2007).
