How NASA Studies Hazards

NASA missions collect data about natural hazards such as hurricanes, earthquakes, and floods. Using that data, scientists develop or refine their theories about the interactions that create these hazards.

They want to detect the conditions that are early warnings, in order to reduce the risks associated with these events. To test their theories, they send up new missions. They share what they learn. That way, we can be warned about where and when natural hazards might occur, know what to expect, and be prepared, if necessary.

Over the next 15 years, an international program called EOS will monitor climate and environmental change on Earth. The leading satellite in this program is called Terra. From Terra will come data for new research about how Earth's lands, oceans, air, ice, and life function as a total environmental system

Tropical Twisters
Hurricanes are what scientists call "strong Tropical Cyclones". Tropical Cyclones are formed when large areas of the ocean become heated and the air pressure over that area drops, this in turn causes thunderstorms and strong surface winds. Find out about how hurricanes work and what they do.
