3D Seismic exploration is comparable to a medical ultrasound, aiming to visualise the Earth’s interior without physical excavation. This is achieved by generating sound waves that penetrate deep underground. Specialised vehicles, known as vibro trucks, move across the survey area, producing controlled surface vibrations. These sound waves travel through the subsurface and are reflected by different rock layers. The returning signals are then captured by highly sensitive sensors called geophones, allowing for the creation of detailed geological models.

2D Seismic exploration: The purpose of the 2D seismic survey is to analyse the subsurface along specific survey lines. Based on this data, which already provides information about possible locations, we then define the measurement network for the subsequent 3D seismics. This then provides us with a comprehensive picture of the subsurface, helping us to find the optimal location.

Minor damages resulting from 3D Seismic cannot be entirely ruled out despite all precautions. During seismic surveys, the following types of damage may occur, although unlikely:

• Vibro trucks leave tracks.
• Vibro trucks compact the ground.
• Hairline cracks may appear on the plaster of buildings.

To minimise risks of structural damage, the truck’s vibrations are continuously monitored using vibration monitoring according to DIN 4150 standards, and the risk to the building structure is minimised by adjusting the intensity of vibrations accordingly. In areas with sensitive infrastructure, specific points of stimulation are omitted when necessary.
