Disasters such as flood, fire, cyclone, earthquake and tsunami expose human, infrastructure and institutional vulnerabilities, and subject communities to considerable impact and loss. Such events make headlines when they cause injury, death and widespread damage. However, their full impacts often remain poorly quantified, but will be felt through long-term consequences for individuals, communities, infrastructure, the landscape and the economy.
The purpose of an impact assessment is to learn about what has been affected by an event and understand both the short and long-term consequences of the event. Armed with this information, we can take steps to reduce the negative impacts and improve the community's future resilience to these events.
