An energy source for shear wave within the surface of the earth. The energy source has a convoluted shape (405). In a preferred embodiment, the pitch of the spacing (425) of the flexible explosive material (405) and the flexible transfer material (430) around the tube (410) ranges from about 20 to 45 degrees relative to the horizontal direction in order to optionally excite a range of frequencies. An energy source for shear waves within the surface of the earth. The energy source has a convoluted shape. L'invention concerne une source d'énergie destinée à engendrer des ondes de cisaillement à la surface de la terre. Cette source d'énergie a une forme en spirale.
