A Recommendation for the Application of the Roch Index for Slab Avalanche Release
Abstract Detailed measurements on several avalanches verify that a Daniels’ (1945) type statistical correction to Roch’s (1966) stability index would accurately predict snow-slope instability. It is recommended that one-half the median of at least 50 shear-strength measurements be used as a measure...

| Summary: | Abstract Detailed measurements on several avalanches verify that a Daniels’ (1945) type statistical correction to Roch’s (1966) stability index would accurately predict snow-slope instability. It is recommended that one-half the median of at least 50 shear-strength measurements be used as a measure of the strength of a weak layer. |
