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 acquiring a ground seismic dataset over a region of interest by defining a geometry of acquisition of the seismic dataset specifying a location of a plurality of seismic sources and a location of a plurality of seismic receivers, inducing a seismic signal with at least one first seismic source of the plurality of seismic sources, and measuring the corresponding ground vibrations induced by the at least one first seismic source with the plurality of seismic receivers to obtain a first seismic dataset. Then processing the first seismic dataset and modifying the geometry of acquisition of the first seismic dataset by specifying a location of at least an additional seismic source and/or a location of at least an additional seismic receiver, based on analyzing the processed first seismic dataset.

Abstract: The probe includes a hollow casing defining a closed inner compartment, the hollow casing having at least an end to be placed in contact with the ground; at least a sensor received in the closed inner compartment, the sensor being able to sense a physical quantity related to the ground; and at least an emitter received in the closed inner compartment, the emitter being able to send data representative of the physical quantity sensed by the sensor. Also, at least a power source received in the closed inner compartment, the power source being able to power the sensor and/or the emitter. At least part of the sensor and/or at least part of the emitter is biodegradable.

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.
