New innovative mobile shaker for reflection seismology - specially optimized for use in urban areas.
This project is implemented in close collaboration of Geophysical Institute of the Karlsruhe Institute of Technology (KIT) and Herrenknecht AG. The development project is supported by the Federal Ministry for Economic Affairs and Climate Action on the basis of a decision by the German Bundestag.

The Herrenknecht Urban Vibro Truck excites the ground by the shaker generating seismic waves that propagate and are reflected at the boundaries of the geological layers. These reflection waves are recorded by geophones and projected to the point of their reflection in data processing. The result is the mapping of geological boundary layers.
The Herrenknecht Urban Vibro Truck is a mobile P-wave vibrator for use in reflection seismic surveys. These subsurface exploitations are necessary to locate geothermal heat sources and assess its heat source potentials. The technology is therefore a crucial prerequisite for a successful transition to a decarbonized heat and power supply industry.
The new mobile Urban Vibro Truck will provide best performance in urban seismic surveys. Its maneuverability, agility and modern design will significantly improve the machine handling within urban regions, towns and cities. In addition, the machine complies with European standards and has EU road approval. All this will contribute to raise the general public’s acceptance on conducting Vibroseis surveys in urban regions.
The new mobile Urban Vibro Truck´s shaker provides broad frequency band capability with high peak force output at low frequencies. Improved system design brings better source signal quality that leads to deeper penetration depth compared to state-of-the-art products.
On the basis of the subsurface mapping obtained, deep drilling for geothermal power plants can be planned. Source: DMT
