The magnitude of the torrential lavas could be better anticipated – Torrential lavas: magnitude could better
EPFZ researchers have identified new factors that make the flows of mud destructive. Meanwhile, This discovery opens the way to better prevention.
A recent EPFZ study revealed “so far unexplained” factors, which “determine the destructive force of torrential lavas”.

Blating, Brienz, Lourtier Or Bondo, all these Swiss villages faced landslides and torrential lavas that have made an impression. Similarly, A recent study of l’EPFZ published torrential lavas: magnitude could better in “Communications Earth & Environment”. relayed by the RTSrevealed “so far unexplained” factors, which “determine the destructive force of torrential lavas”.
The researchers particularly looked into the torrential lava which had started in June 2022 in the Illgraben, above Loèche. Thanks to several measurement stations. scientists were able to observe the mud flow and particularly noticed that “powerful and fast waves occurred regularly on the surface,” reports the statement of the EPFZ.
According to Jordan Aaron. professor of geology of the engineer at the EPFZ, “we have long known that these pushes play a central role in the destructive force of the mudslides. Because they make the flows particularly powerful and fast ”.
Better predict the extent of the torrential lavas
The observation. of the phenomenon of 2022 torrential lavas: magnitude could better to Loèche therefore made it possible to learn more about these waves. An important advance: “The dangerousness of a mud flow is indeed defined largely by the destructive force of the thrusts”. details the press release.
These measures could therefore allow “to estimate in the future if thrusts are to be expected during a torrential lava. what is their destructive force. We could thus deduce the forces to which the walls of the houses. the pillars of the bridges must resist in an area of danger ”. This will also make it possible to set up prevention measures, such as nets or dikes.
