WebEarthquakes occur because stresses build up between the plates as one plate passes another. As the plates move past one another they don't do so smoothly, rather, they snag and grind, allowing energy to build up. When the plates eventually move again this energy is released as shock or seismic waves through the Earth's crust. WebJan 28, 2013 · Large-amplitude surface waves from the 2011 Tohoku-Oki earthquake triggered many seismic events across Japan, while the smaller amplitude P-wave triggering remains unclear. A spectral method was used to detect seismic events triggered by the first arriving P-waves over Japan. This method uses a reference event to correct for source …

WebFigure 6. Love waves move in a snake‐like motion parallel to the Earth’s surface. Destructiveness of Seismic Waves Both Rayleigh and Love waves are more destructive to buildings than are P‐ and S‐ waves. Because of the vertical motion produced by Rayleigh waves they tend to be the most WebAnswer (1 of 4): The three types of waves are: the primary or P-waves (also called compressional or longitudinal waves), the S-waves (also called shear or transverse waves) and the surface waves. The P-waves are the fastest travelling waves and are the first to arrive at any point on the earth. ...
