expedition team started the trip with the aim to install
a seismographic station at "Ojos del Salado" as high as possible. The earth
vibrations of the highest volcano of the earth can be measured with this station. Chile is located in a region which is hit most frequently
the frame of its researches in South America, the renowned "GeoForschungszentrum
Potsdam (GFZ)", Geological Research Centre of Potsdam, made the measuring
station available to the expedition team.
seismograph was installed by Rainer Zietlow and his team at 5,850m (19,188ft), about 500m (1,640ft) air-line distance from the peak
of Ojos del Salado. Powered by solar energy, the seismograph registers
every ground motion over a period of nine months.
