A GPS station for continuous measuring at height was installed through the SIGMA program (GPS Mt.Aconcagua Research System) in 2005 at the summit of the Aconcagua. The station is named ACON. Important quantities of data have been obtained during 2008 that have been processed and analyzed. This yielded the displacement velocities in their three dimensions. Gravimetric studies were jointly performed to contribute to the study of the internal structure of Mt. Aconcagua for understanding its displacement. In the first field trip of 2009 we have carried out gravity measurements in the transect between the city of Mendoza (absolute gravity point) until the site called "Plaza de Mulas", at 4450 m asl within the Parque Provincial. The intention is to extend these determinations until reaching the summit of the Aconcagua during the next year.
