Seismic Imaging and Monitoring at GEUS

We offer the full range of solutions from survey design to geological interpretation for applications such as CO₂ storage, geothermal energy, mineral exploration, geohazards and groundwater management.

Services

Seismic land person

Land seismic studies

High-resolution seismic imaging of subsurface structures, combined with geological interpretation, is essential for applications such as CO₂ storage and geothermal energy. 

Earthquake monitoring

Observation of both natural and induced earthquakes are important for many uses of the subsurface.

Seismic marine boat

Marine seismic studies

Marine seismic data acquisition is the tool of choice to obtain detailed images of subsurface structure including physical properties in offshore areas.

Solutions

We provide advanced geophysical solutions specializing in land and marine seismic studies and earthquake monitoring — delivering reliable data to support the green transition, mineral exploration and risk mitigation efforts.

Previous studies

Moen klit

Imaging the glaciotectonic complex at Møn, Denmark

In May 2025 we did active and passive seismic acquisition at Møn, Denmark, to image the impressive glaciotectonic complex which raises up to 128 above sea level along the coast.

Seismic truck

Vibroseis at Lesbos, Greece

In October 2024, the Seismic imaging and monitoring group provided the vibroseis source for 25 km 2D profiles for an evaluation of the potential for geothermal energy in the island of Lesbos.

Boat on ice

Marine seismic acqusitions

In the Baltic Sea, west of Svalbard, in the fjords of Greenland, the North Sea and in the marine gap between Sjælland and Nekselø.

Stenlille

Earthquake monitoring at Stenlille

Monitoring for micro earthquakes at the Stenlille underground gas storage facility, Denmark.

Research output

The work offered by the Seismic imaging and monitoring group at GEUS is based on extensive scientific knowledge and innovation.
