S-wave speed

SpletWave speed equation (Speed = Wavelength x Frequency) relates wave speed to wavelength and frequency. When the wavelength and frequency are known, this equation can be used to calculate wave speed. Wave frequency is the number of waves that move per second. In addition, the duration is calculated as the reciprocal of the frequency of the wave. Splet01. dec. 2011 · Within the upper few hundred metres below the seafloor (mbsf), the seismic velocities of poorly consolidated sediments containing no hydrate or free gas are typically 1600-1800 m s -1 for P -waves and 300-800 m s -1 for S -waves.

Among the many types of seismic waves, one can make a broad distinction between body waves, which travel through the Earth, and surface waves, which travel at the Earth's surface. Other modes of wave propagation exist than those described in this article; though of comparatively minor importance for earth-borne waves, they are important in the case of asteroseismology.
