The "Laboratoire de Géodynamique des Chaînes Alpines" (LGCA) (Laboratory of Alpine Belts Geodynamics) is a laboratory of both University of Savoie (Chambéry) and University Joseph Fourier (Grenoble). The LGCA is also an associated Laboratory of the "Centre National de la Recherche Scientifique" (CNRS) (ESA nr 5025). The LGCA has a staff of 30 academic people, and about 40 reaseach students. The LGCA belongs also to the Grenoble Astronomy & Earth Sciences Observatory. Among the main fields of research at the LGCA is the characterization, measure and modelization of recent and present-day deformation. Ongoing GPS studies concern the Himalayas, the Alps and Iceland where the LGCA follows a network of 45 GPS points since 1995. The LGCA has also installed and maintained 5 stations among a continuous GPS network in the Alps (REGAL network). The LGCA monitor deformation with GPS on several landslides in the Alps.
