SUMMARY: By combining the data from four separate instruments, NASA scientists are able to study the Earth's volcanoes in tremendous detail. Most recently, Italy's Mt. Etna was captured mid-eruption using the instruments on board the Terra and Aqua spacecraft, and the data will help the scientists understand the complex behaviour of volcanic plumes and the effects the eruptions have on the environment.

Mount Etna spews lava on the southern Italian island of Sicily on July 16, 2006.

"The explosions are coming from two holes near to the top of the volcano, creating a lava field more than a mile long which is flowing at a rate faster than 90 cubic feet a minute. Even though the eruption has continued for three days, scientists said it had lost little of its force."
