Terra-2, Terra-2A and Terra-2AM series
Electromechanical sources of seismic vibrations Terra-2, Terra-2A and Terra-2AM - are designed to excite seismic waves in the study of small and medium depths of the geological section by full-wave seismic. Seismic vibrations are excited by vertical impulse force effects on the soil surface.
Spheres of use:
- Study of the upper part of the section when searching for oil, gas and other minerals.
- Engineering and construction surveying, before the construction site of subways, power plants and other large objects.
- Environmental studies conducted in order to identify groundwater.
- The study of karst phenomena and landslides.
- Archaeological research.
