Fig. 4From: The role of initial coherence and path materials in the dynamics of three rock avalanche case historiesFailure mechanism for the West Salt Creek Rock Avalanche hypothesized by Coe et al. (2016). Panel a shows the topography before failure. The geometry after the slump (green line on panel b and c) was derived from a Dan3D-Flex analysis. Panel d shows the topography after the rock avalanche had vacated the source zone. The section line is shown on Fig. 7 Back to article page
