Figure 3. Landslide response to changes in precipitation. (a-d) Maps of velocity and precipitation ratio by water year. Brown to green color symbols correspond to velocity ratio values for each landslide. Red to blue colors in background correspond to precipitation ratio. Symbols correspond to landslide type. Rock type is shown by black or gray symbol border color. (e-h) Velocity ratio as a function of precipitation ratio for selected landslides. (i-l) Velocity ratio as a function of estimated landslide thickness. Error bars show the uncertainty in the velocity ratio. Red to blue colors correspond to the 30-year mean water year precipitation (WY1990-WY2019) for each landslide. Symbols correspond to landslide type. Rock type is shown by black or gray symbol border color. We calculated the velocity ratio uncertainty using standard error propagation and assumed nil uncertainty in the precipitation data.
