The U.S. Geological Survey has a long history of investigating the causes and consequences of natural and human-induced hazards and disasters; it also works to develop strategies for forecasting them. EROS is a key source of satellite imagery, aerial photos, and other kinds of remotely sensed data that are vital for disaster relief efforts worldwide. These data also form the basis for diverse EROS activities that include drought and wildfire risks, forecasting floods and famines, and studying threats to human health.
