The Walferdange Underground Laboratory for Geodynamics
The Walferdange Underground Laboratory for Geodynamics (WULG) is located in an gypsum mine (originally exploited by a commercial company). The thicknes of the sedimentary surface layer above the central part of the mine system amounts to about 80 meters. The distance from the entrance to the “Old Laboratory” is about 1km and the temperature about 13°C at the terminal of the main gallery where the old laboratory is situated.
This is the ideal place to perform very high precision geophysical measurements. Read more …
