Volcanoes are one of the most powerful natural hazards on Earth, but supervolcanoes are so large that they have the ability to alter the world's climate. Michael Manga from the University of California, Berkeley, is investigating a supervolcano that erupted hundreds of thousands of years ago, and could do so again. See more in this video.

Many of Alaska's more than 130 volcanoes are located along the 1,550-mile-long Aleutian Arc. It extends from the Alaska mainland west toward Kamchatka, Russia, and forms the northern part of the tectonically active "ring of fire" girding the Pacific Ocean basin. To learn more about volcanic hazards in this volatile region, 25 researchers from 11 institutions studied the Aleutian Arc. The research addresses volcanic systems -- from magma storage to the chemistry and style of eruptions -- as well as the earthquake and tsunami hazards that can affect the entire Pacific.

The Division of Earth Sciences (EAR) of the Directorate for Geosciences supports research geared toward improving the understanding of the structure, composition and evolution of the Earth, the life it supports, and the processes that govern the formation and behavior of the Earth's materials.
A team of University of Utah seismologists have discovered a massive pool of hot rock hidden deep beneath Yellowstone's supervolcano.

Kilauea: Up close and personal with red hot science!
This geologist has been taking whatever Kilauea and other active volcanoes dish out for decades, gathering extensive data on eruptions
Hawaii's Kilauea volcano is one of the best places on Earth to study processes within basaltic volcanoes. Its high eruption frequency, easy access to lavas, and distinct geologic setting far from plate boundaries or continents allow researchers to address fundamental problems related to active volcanoes. Kilauea is also one of the longest currently erupting volcanoes -- its current active period began in 1983!
Another constant at Kilauea, besides the flowing lava, has been University of Hawaii geologist Mike Garcia. With support from the National Science Foundation (NSF), Garcia has been leading studies of Kilauea for a generation, adding to the extensive knowledge base on this volcano.
Two of the primary goals are to determine what has triggered Kilauea's effusive, explosive cycles over the last 2200 years and when long eruptions, such as the current one, will stop.
