BLATTEN: The landslide was predictable since space in 2016 – Blitten: landslide predictable birch glacier new
The European space agency has analyzed satellite images showing the warning signs of the collapse of years before the incident.

An analysis of the European Space Agency (ESA) reveals that precursor signs. of thePetit-Asthorn landslide in Blaten were detectable since space several years before the incident last May. Satellite images show that field movements were already underway in 2016 and intensified over time.
The study of l’E’s Confirms that the slope had started a trip long before collapse. indicates Andrea Manconi. expert at the WSL Institute for the study of snow and avalanches (SLF) to our colleagues in Keystone-Ats, quoted by different media including Blue Lake.
Between 2016. 2024. radar images demonstrated a significant acceleration of the movements of the slope, going from 50 centimeters of travel per year in 2023 to 150 centimeters per year the following year.
Special satellites in the blitten: landslide predictable birch glacier L band
This acceleration of deformations reflects a passage to a critical situation. accentuates the risk of an imminent disaster. Thanks to these observations, the use of satellite data is essential for early detection of risks.
The images come from satellites in blitten: landslide predictable birch glacier new L -band. which, thanks to their longer radar waves, offer better capacity to penetrate in complex terrains than traditional satellites.
Although local observations have enabled the inhabitants of Blatten in time. ESA highlights the crucial importance of these satellites for large -scale surveillance. However, the agency is aware that deploying sensors on each alpine slope is logistically and financially impracticable.
