SUGGESTIONS FOR NARROWING THIS TOPIC Analyze the recreational aspects of volcanoes. Resources on this topic are not limited to those described and availability will depend upon the individual library.
Supervolcano is the popular term for a large volcano that usually has a large caldera and can potentially produce devastation on an enormous, sometimes continental, scale.
Such eruptions would be able to cause severe cooling of global temperatures for many years afterwards because of the huge volumes of sulfur and ash erupted. Examples include Yellowstone Caldera in Yellowstone National Park of western USA, Lake Taupo in New Zealand and Lake Toba in Sumatra, Indonesia.
Researchers have found a new way to estimate how fast magma is recharging beneath the Yellowstone supervolcano.
While their findings offer no help in predicting if the volcano will erupt, they can ...

On the basis of their analysis of the satellite data, the team found that the majority of the 47 volcanoes were on a spectrum between open systems—able to release gas and pressure—and closed systems, which are likely building up internal pressure.
In addition, an in-depth study of the Copahue volcano on the Chile-Argentina border showed that its eruptions are preceded by a regular cycle of ash plumes, gas venting, and increased thermal activity and internal pressure, all of which can be effectively tracked from space.
