Abstract
A method of seismic exploration is disclosed wherein an explosive charge is placed in a hole in the ground and wherein a detector is placed in a second hole spaced away from the first hole. The detector is mounted in the bottom of the hole by using an adherent base. The mouth of the hole is sealed to form a quiescent volume in the hole for the detector. Thereafter, the explosive charge is discharged and the output of the detector is recorded.
