Definition
Determine the Sensitivity to Triggers based on what kind of triggering will initiate avalanches of any size within the defined location.
| Sensitivty | Natural Triggers | Human Triggers | Explosive Triggers | Cornice Triggers | |
| Size | Result | ||||
| Unreactive | No avalanches | No avalanches | Very large explosives | No slab | No slab from very large cornice fall |
| Stubborn | Few | Difficult to trigger | Large explosives & air blasts | Some | Large |
| Reactive | Several | Easy to trigger with ski cuts | Single hand charge | Many | Medium |
| Touchy | Numerous | Triggering almost certain | Any size | Numerous | Any size |
| Description of observation | Natural avalanche occurrence | Ease of triggering by a single human | Size of explosive and effect | Size of cornice that will trigger a slab | |
