What is the benefit of a disaster warning system?
Answer and explanation
Correct answer: Alerting people in advance
A disaster warning system detects or monitors a hazard, analyses expected danger and communicates timely information to exposed communities. Warnings about floods, cyclones, tsunamis or severe weather give people time to evacuate, protect belongings, move livestock, arrange medicines and follow official instructions. This advance action can reduce deaths, injuries and property loss, so option A is correct. A warning cannot remove every effect of a disaster and cannot stop a natural hazard from forming; therefore options B and C are exaggerated. Information delivered only after the event is too late to provide the main benefit. The governing concept is early warning linked with preparedness, communication and effective response.
