Satellite data has increasingly played a vital role in monitoring and responding to natural disasters and environmental hazards. Providing an overview of a developing situation or its aftermath from orbit, this data is very useful for forecasting a hazard or helping to coordinate relief.
Examples of this can be seen in the Natural Disasters section of this website, featuring ESA imagery made available for major disasters.
The Environmental Hazards section features other hazards that do not fit under those categories, such as sandstorms or heavy snow.
