earthquakes deform the ocean floor, they often generate strong tsunami waves. Subduction zone earthquakes are also known to produce intense shaking and...

Overall, S waves are shear waves, and shear stress is a type of deformation that cannot occur in a liquid. Conversely, P waves are compressional waves and are...

magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included to compensate for the...
