In addition, advances in telecommunications allow data from remote areas to be quickly incorporated and other data to be sent to them. Small disasters may be evaluated and responded to at a local level. There needs to be further work done to develop appropriate technology and equipment. However, more widespread disasters will certainly require assessment at provincial and perhaps national levels. This would apply to satellite data particularly.
Communities often know who is most vulnerable.
Existing development forums in rural areas could be asked to collect and monitor early-warning data required for their area. Early-warning systems therefore ideally work best at the local level. Early-warning systems should also be able to integrate information and early warnings mechanisms from regional states. This will inform the kind of decisions that need to be taken about a particular hazard and the institution of plans that an authority can realistically deal with in different phases of a disaster. Vulnerability analysis shows how a hazard will act on different groups.
