Satellite images and geodetic measurements applied to the monitoring of the Horcones Inferior Glacier, Mendoza, Argentina

this work analyzes the monitoring of the covered and regenerated horcones inferior glacier (hig) since the implementation of a semi-permanent gnss station (hiss) on its surface during the summer seasons of 2009 and 2010. the glacier is located at 32° 41's and 69° 57'w, at the foot of the south wall of mt. aconcagua, aconcagua provincial park, mendoza, argentina. the average velocities obtained from the hiss station were of 1.3 cm/d and 3.5 cm/d during the 2009 and 2010 seasons respectively. the data procured using satellite images during the last surges (1984 and 2003) gave average velocities for the hig front of 8.7 m/d for the first event and 11.5 m/d for the second one. these results allowed getting accurate and reliable movement tendency at the terminal part of the hig during the 1984-2010 period.
