If you flew over an earthquake, would you feel the plane shake?

The earthquakes release seismic waves in the form of pressure and shear waves (or P and S waves). When P waves leave a solid object, like the crust, and enter the atmosphere, they take the form of sound waves (S waves can't travel through liquids or gases). However, P waves typically register below the 20-hertz threshold for human hearing [source:USGS]. Scientists describe waves that fall in this range as infrasound.

People hear an earthquake and do not hear the seismic waves released. Rather people feel the difference between the sound produced when seismic waves move through the solid matter like the rumbling of a building and its contents. Rather one would  not be able to detect these sounds nor feel the infrasound waves from an airplane. Thanks to the Physicists call attenuation, the waves gradually lose intensity as they move through the medium of the air.

Likewise the seismic waves reached the cruising altitude of 30,000 feet (usually the airplanes  fly), they would be so diminishing by their journey through the medium of rocks and air that the noise and the motion of the airplane would overpower the waves. So you would not be able to hear the earthquake from the aircraft and will not certainly feel it.
