Abstract: The method comprises providing at least one seismic source in a seismic source area and providing a plurality of seismic receivers in said seismic source area, said method comprising measuring a first type of ground vibrations induced in a subsurface of the area of interest by the at least one seismic source with the plurality of seismic receivers. The method further comprises measuring with the plurality of seismic receivers at least one second type of ground vibrations induced by a mechanical source different from the or from each seismic source and analyzing the second type of ground vibrations to determine at least one information among: a physical parameter of the subsurface and/or, a presence of human and/or an animal and/or a vehicle.

Abstract: The tool comprises-: a support comprising at least a lower surface intended to rest on the ground; a lifting system, carried by the support, the lifting system having at least a movable extraction member able to cooperate with the seismic apparatus and an actuator able to actuate the extraction member to lift the seismic apparatus out of the ground, the distance separating vertically the lower surface from the lifting system being at most 2 m.

Abstract: The method comprises flying at least a probe carrier flying vehicle above a dropping area on the ground, the probe carrier flying vehicle carrying probes and a launcher, configured to separate each probe from the probe carrier flying vehicle; activating the launcher to separate at least one of the probes from the probe carrier flying vehicle above the dropping area; falling of the probe from the flying vehicle in the ground of the dropping area; at least partial insertion of the probe in the ground of the dropping area. When the probe carrier flying vehicle is located above a target dropping area, before activating the launcher, the method comprises determining a vegetation information at the target dropping area using a flying vegetation detector.

Abstract: The invention concerns a method for evaluating a geophysical survey acquisition geometry over a region of interest. The method comprises determining a location of a plurality of base camps in respect of a determined minimal surface density of base camps, determining a first set of locations of a plurality of receivers in respect of a determined minimal surface density of receivers, generating a first synthetic geophysical dataset based on the first geophysical survey acquisition geometry, processing the first synthetic geophysical dataset for obtaining a first simulated image of the subsurface of the region of interest using a geophysical processing algorithm and an a priori subsurface model, and calculating a first objective function dependent of at least a first quality index of the first simulated image of the subsurface of the region of interest.
