Question

Both scenarios describe areas with steep slopes and loose ash or snow, which are prone to mass wasting events such as lahars (a type of mudflow composed of volcanic ash and other debris) triggered by heavy rainfall, or volcanic eruptions that can melt the snow cover on the mountain triggering lahars as well. Slumps, rockslides, and debris avalanches could also occur in these scenarios, but they would not necessarily be related to the volcanic activity or ash/snow cover. Creep is a slow, gradual movement of soil or sediment that is not likely to be triggered by heavy rain or volcanic activity.
