Rotatable horizontal vibrator
This patent describes an improved seismic energy source mountable with a vehicle for imparting shearwave energy polarizations between 0{sup 0} to 360{sup 0} into the earth at the same location without repositioning the vehicle, comprising (a) a vibratory pad adapted for contact with the earth; (b) vibratory means mounted with the vibratory pad adapted to impart a linear vibratory motion to the vibratory pad whereby swept frequency shearwave seismic energy of a selected polarization can be imparted into the earth; (c) means with the vehicle for raising and lowering the vibratory pad into contact with the earth; and (d) means with the vehicle for horizontally rotating the vibratory pad and vibratory means individual azimuthal radial orientations between 0{sup 0} to 360{sup 0}, whereby when the vibratory pad is in contact with the earth, swept frequency shearwave seismic energy can be imparted in any polarizations between 0{sup 0} to 360{sup 0} thereby reducing data acquisition time and eliminating vibratory pad misplacement induced data errors.
