Today I participated in a round table discussion at the 10th International Symposium on Landslides and Engineered Slopes. The topic of the discussion was: “Strength criteria and design approaches for difficult soils and rocks”. Each of the four panelists was asked to talk for 10-12 minutes before the panel discussion started. I was asked to talk about “Slow Moving Rockslides”. So, below is my deliberately somewhat provocative presentation. (there appears to be a fault on slideshare that is preventing this from being visible on blogger. If it is not visible below, you can get it from here)
