LUXBB: temporary deployement of six broadband seismic stations in Luxembourg
In a collaborative project between the European Center for Geodynamics and Seismology and the Geophysical Institute of the Karlsruhe Institute of Technology (KIT), six broadband seismic stations from the Karlsruhe Broadband array (KABBA) are deployed in Luxembourg for a timespan of 12-18 months. The deployment started in December 2009 and currently, four of the six planned sites are fully operational.
Analyzing earthquake ground motions: insights into source characteristics, seismic attenuation and site amplification
The observed ground motion resulting from an earthquake is the convolution of mainly three contributing factors: source, path and site effects. In order to get better insights into earthquake source physics and the attenuation of seismic waves in the Earth’s crust as well as to improve seismic hazard estimates, it is necessary to separate these contributions from each other.
CORSAIR – COntinental Rift SAr InteRferometry
Continental rifting comprises in a single term, one of most complex geodynamical settings of the plate tectonics. The pan-African rift valley is the largest continental rifting zones in the globe, as a dichotomy is also one of the less known plate boundaries. Deformation measurements has been proved of capital importance to decipher the driven-force mechanism sources involved from plate-scale tectonics, through regional seismogenic faults to local-scale magmatic plumbing systems.

Using GPS and Gravity to Infer Ice Mass Changes in Greenland
Climate research indicates that global warming is occurring and will probably continue to occur for the next several decades. One consequence of a global warming scenario is a global sea level rise that would be expected from 1) the thermal expansion of the near surface ocean water and 2) the melting of the Antarctic and Greenland ice sheets and continental glaciers.
International Intercomparison of Absolute Gravimeters
On November 3rd to November 7th 2003, Luxembourg’s European Center for Geodynamics and Seismology (ECGS) hosted an international intercomparison of Absolute gravimeters in their Underground Laboratory for Geodynamics in Walferdange (WULG).
The GRAVILUX project
The Grand Duchy of Luxembourg is establishing a new International Reference Station for Intercomparisons of Absolute Gravimeters (ISIAG). The station is located in the Walferdange Underground Laboratory for Geodynamics 100 meters below the surface. Since 1967, the laboratory has been used for Earth tides research and from that work has gained an international reputation as a seismogenically quiet location where sensitive instruments can be tested and evaluated.
