Maps depicting the hazards and impacts of landslides or other mass movements. which could include snow avalanches.

Situational.When might it be produced?
When landslides pose the main or a secondary humanitarian hazard, particularly in association with earthquakes or storm events (particularly after very heavy rainfall). Maps may be produced to identify areas vulnerable to landslides in order to identify at risk communities, or to prioritise on-the-ground or aerial damage assessments. Landslides may also be mapped to identify barriers to access to disaster-affected areas.
All responders, but particularly those working on assessment processes and response planning and coordination. Also, when relevant, logistics planning actors.Influence on humanitarian decisions
Landslides can have a direct impact on communities, and can also block access to large areas of land. Maps showing known/confirmed landslides may be valuable as proxy indicators of likely damage and needs after an earthquake or storm event. Predictive mapping should be used only with caution.
