Matterock methodology
A methodology for monitoring cliffs and detecting potential major landslides The major rockfall at Randa (Valais, Switzerland) in the spring of 1991 (30 Mom3) highlighted the scientific shortcomings in predicting such catastrophic events. It was therefore decided to develop a cliff monitoring methodology that would provide a better understanding of the phenomenon of cliff instability and anticipate potential rockfalls. This methodology, called MATTEROCK, was developed as part of the National Research Program… Read More
