A large piece of rock broke off on the north face of the Eiger on Saturday morning, causing a massive cloud of dust, as reported by the Tagesanzeiger. Such rockfalls are not uncommon, explains Kathrin Naegeli, media spokeswoman for Jungfrau Railways. "The last time this happened was at the beginning of August," says Naegeli.
The cause of the rockfalls is the melting permafrost. Jungfrau Railways is now investigating whether hiking trails need to be closed. However, Naegeli emphasizes that the Eiger Trail is currently not at risk and can still be used.
A picture shared on social media shows the extent of the natural disaster. The huge cloud of dust caused by the rockfall illustrates the force of the collapse.
Heute Morgen ereignete sich an der #Eiger-Nordwand ein #Felssturz. Der dabei entstandene Staub breitete sich unter einer Temperaturinversion in der Umgebung aus und wurde von unserem Messgerät (Ceilometer an der Kleinen Scheidegg) registriert. https://t.co/ViXABuuLU0pic.twitter.com/T5btYdcFxp
As reported by Meteo Switzerland on Platform X, the dust spread in the surrounding area due to a temperature inversion. The dust was registered by a measuring device at Kleine Scheidegg.
