In disaster planning, which term refers to the speed of onset and anticipated duration of an incident?

Explanation:
Imminence describes how quickly an incident begins and how long it is expected to last. In disaster planning, understanding imminence helps determine how fast to alert responders, mobilize resources, and implement protective actions like evacuations and sheltering, since rapid-onset events require quick decision-making and short response windows, while longer-lasting incidents demand sustained capabilities. The other terms don’t capture this timing aspect: frequency is about how often events occur, predictability is about foreseeing timing, and mitigation focuses on reducing harm before and during an incident.
