Their shear wave velocity reduction is on the order of-10 to-30 % and the compressional wave velocity reduction tends to be weaker.
32.
Dynamic characteristics of site such as predominant period, amplification factor, shear wave velocity, standard penetration test values can be used for seismic microzonation purpose.
33.
Here a 100 km by 225 km mass of relatively high density ( fast p wave velocity ) has been discovered below an area of anomalous topography.
34.
Earthquake ruptures typically propagate at velocities that are in the range 70 90 % of the S-wave velocity, and this is independent of earthquake size.
35.
In contrast, a typical earthquake rupture velocity is 70 to 90 % of the S-wave velocity, or approximately 3.5 km / s.
36.
Sinusoidal traveling plane wave entering a region of lower wave velocity at an angle, illustrating the decrease in wavelength and change of direction ( refraction ) that results.
37.
In the emitter's frame, the wave has frequency propagates with wave velocity, measured in the direction shown with the magnitude equal to speed of propagation.
38.
Wave velocity is a general concept, of various kinds of wave velocities, for a wave's phase and speed concerning energy ( and information ) propagation.

Wave velocity is a general concept, of various kinds of wave velocities, for a wave's phase and speed concerning energy ( and information ) propagation.
40.
Shear wave velocity measurement and standard penetration test are generally expensive and are not feasible to be carried out at large number of sites for the purpose of microzonation.
