Effective early warning systems embrace the following aspects: risk analysis; monitoring and predicting location and intensity of the disaster; communicating alerts to authorities and to those potentially affected; and responding to the disaster. EO includes measurements that can be made directly or by sensors in-situ or remotely (i.e. satellite remote sensing, aerial surveys, land or oceanbased monitoring systems, Fig. 3 ), to provide key information to models or other tools to support decision making processes. For each hazard type, a gap analysis has been carried out to identify critical aspects and future needs of EWS, considering aspects such as geographical coverage, and essential EWS elements such as monitoring and prediction capability, communication systems and application of early warning information in responses.	./cache/cord-021081-yqu1ykc9.txt	./txt/cord-021081-yqu1ykc9.txt
