Sometimes this is referred to as mitigation. Examples include prescribed burning or constructing flood mitigation dams, having back-up generators or alternative communication systems in place. Prevention activities occur prior to disasters. • Preparedness – making arrangements, creating and testing plans, training, educating and sharing information to prepare organisations and communities before a disaster occurs. • Response – the assistance and intervention during or immediately after a disaster. Focus is on saving lives and protecting community assets (buildings, roads and infrastructure) and the environment. • Recovery – the coordinated process of supporting emergency-affected communities in reconstruction of physical infrastructure and restoration of emotional, social, economic and physical wellbeing. Recovery can be required for months and/or years after the disaster.

Risk assessments used The National Each Zone has a Zone Emergency Management Emergency Risk Assessment Committee (ZEMC) made up of Local and State Government and emergency management Guidelines based on ISO 31000 staff. These committees have a risk assurance to ensure a consistent and role and provide regional leadership in rigorous approach. emergency management in their Zones. One of their main roles is the development of a Zone Emergency Management Plan. This is important as understanding the potential impact of disasters on the region is essential for planning and preparation.
