Massive landslides and rockfalls occurred in Weggis on Monday, described by an eyewitness as "trees crackling on the Rigi slope." Rocks were dislodged and trees toppled; one boulder struck a house wall, prompting the precautionary evacuation of a single-family home with four people and 30 sheep. Tannenbergstrasse and parts of Zingelistrasse were closed, and protective barriers were installed, while geologists and emergency services continuously monitored the situation at the foot of the Rigi. The public is strongly urged to avoid the affected area and strictly observe all barriers.
