From controlled earthquakes to the monitoring of unstable slopes
How do earthquakes occur? Seismologist Anne Obermann from the Swiss Seismological Service, together with a research team from Paris, has applied unsupervised machine learning to data from ETH Zurich’s BedrettoLab. The collaboration was made possible by the Germaine de Staël funding programme. The method identified significantly more seismic events than the previous reference catalogue. This now opens up a broader perspective: initial analyses of data from the Blatten ice and rockfall suggest that the activity of an unstable slope may already be trackable using just a single seismic station. In an interview with the SATW, Obermann explains how a research collaboration gave rise to a new idea for monitoring natural hazards.
