WebbP waves are recorded earlier than S waves, because they travel at a higher velocity. ... P waves can travel through liquid and solids and gases, ... A type of seismic body wave in which rock particles vibrate at right angles to the direction of wave travel. Secondary waves cause the rocks they pass through to change in shape. ... Webb1 feb. 2015 · And the scatter of the SH first arrival amplitude at atmospheric pressure is also ±40%, as some signals with very low amplitude should be excluded from the signal processing. On the contrary, at 50 MPa, scattering of SH wave amplitudes is about 15%.
