A highlight of the meeting was the field trip to the Gornegraat peak, at 3,130m elevation. From the panoramic view point offered by the peak, in the late afternoon of 19 September 2012, the Gamma Portable Radar Interferometer (GPRI) measured surface deformation of (from left to right) the Grenzgletscher, Schw√§rzegletscher and Breithorngletscher. In a period of 1 hour and 33 minutes, the GPRI performed 32 successive scans, with an interval of 3 minutes between each scan. Analysis of the images allowed determining the average displacement rate, expressed in the figure below by the daily rate of movement. The red colors identify surface movements, very clear for theSchw√§rzegletscher.
