Spherical Seismic Waves
Spherical Seismic Waves
This Demonstration shows the propagation of spherical elastic waves, commonly known as seismic waves, from a point source. Shown here are two types of seismic waves: pressure wave (P-wave) and shear wave (S-wave). The P-wave is longitudinal, and thus oscillates along the direction of the wave propagation, while the S-wave shakes perpendicular to the travel direction.
By combining these two types, you can simulate other types, such as Rayleigh waves.
