The outermost solid shell of the Earth, the Earth’s crust, is regarded by human beings as their foundation. To understand and survey this anthroposphere, as well as to make predictions about its evolution and use is the task of near-surface and applied geophysics. In doing so, it is equally important to understand the global processes of plate tectonics and what drives geodynamics, as well as it is to study small-scale phenomena that, for instance, may influence the decision how to utilize the subsurface (e.g., exploration, water, infrastructure). Equally, imaging, quantification, and assessment of geohazards at an early stage (e.g., mass movements, sinkholes, environmental changes) are challenging, the more if they occur in urban areas.
In order to explore the subsurface we apply various geophysical methods which are sensitive for different physical properties. In four working groups we concentrate on seismic and electromagnetic methods. In field experiments and on the computer - and supported by innovative developments of measuring instruments - these methods are further developed. With the help of simulations these methods are used for predictions of the subsurface structure of the subsurface and the involved processes.
Our aims and tasks
- Carry out basic and applied research as entity.
- Foster prediction capabilities with non-invasive measurements. Enhance exploration and monitoring for and during subsurface use.
- Aid assessment of natural hazards and georesources.
- Develop quantitative methods especially for urban areas and related to hazards.
- Provision of large infrastructure for the geo-community
Infrastructure, instrument development and field measurements
The "Geophysical Instrument Pool Potsdam (GIPP)" provides seismic, magnetotelluric and geodetic instruments and sensors for projects of GFZ groups, universities and other research facilities. It is hosted by our Section 2.2 "Geophysical Imaging" and Section 1.1 "Space Geodetic Techniques" of the GFZ Helmholtz Centre for Geosciences.
Large part of our activities is devoted to the development of scientific instruments, i.e. digital data recorders. The infrastructure and the innovative instruments form the base for our extensive field measurements.
