The scientists made their recordings at an altitude of 2,500 metres. Patrick Paitz - Seismic monitoring of glaciers is essential to improving our understanding of their development and to predicting risks. SNSF Professor Fabian Walter has come up with a new monitoring tool in the form of optical fibres. The fibres are capable of monitoring entire glaciers. Glaciers are constantly moving and they therefore need monitoring. Satellite images give clues to their development. By listening to glaciers from inside, seismology enables scientists to understand their movements with greater accuracy.
