Where it is possible to give warnings (as a result of monitoring), in order to enable action to prepare.

Resilience

Ability of individuals/communities to utilise available resources in order to respond, withstand and recover from the effects of natural hazards.

Park model (disaster Response curve)

A model that demonstrates how hazard events have varying impacts over time. Showing pre disaster, when the disaster happened, response and post-disaster.

Disaster relief

(part of the park model) involves rescue services, medical attention and general care. Lasting between a few hours-days.

Disaster rehabilitation

(next stage of the model) People provide shelter, food and water for those affected to try and resume to some sort of normality. Lasting between a few days-weeks.

Disaster reconstruction:

Where property and infrastructure is repaired/rebuilt, crops are regrown etc. People use this time in order to learn from that event for the future.
