(Complete Item Description)
- Abstract: This animation is a zoom into the Ongoing Mount Etna Eruption. The data was acquired from the MODIS instrument at 9:40 UTC on July 24, 2001. The Ash Plume and lava streaming from the volcano are clearly visible.

- Abstract: This video segment adapted from NOVA relates the dramatic story of vulcanologists trying to predict the timing of the cataclysmic eruption of Mount Pinatubo in the Philippines.

- Abstract: This video segment adapted from NOVA features footage of the aftermath of the 1991 Mt. Pinatubo eruption in the Philippines, including falling ash and mud flows.

- Abstract: This multimedia resource produced for Teachers' Domain chronicles the 1980 volcanic eruption of Mount St. Helens. Featured are still images of the devastation, video of the eruption plume, and before-and-after satellite images of the affected region.

- Abstract: This is simple zoom into the Mount Etna eruption. The plume from the ongoing eruption has changed color since the last SeaWiFS image. In todays image, collected around 7:00 am EST, the ash plume has a greenish orange color in this 670-555-412 nanometer composite.

- Abstract: This recent false color Landsat-7 image, from January 2001, shows Mt. Pinatubo as it stands today. The caldera is seen in the middle of the image, underneath clouds. Ten years after the blast, vegetation is re-growing on the slopes of the mountain (in green.) Streams of mud, called lahars, (resulting from ash from the eruption mixing with water- seen as the lighter sediment) continue to flow down the sides of the mountains, as well as channels of water (darker streams). However, as vegetation grows back, the ash becomes more stabilized and less likely to form the destructive lahars.

- Abstract: Students observe an in-classroom visual representation of a volcanic eruption. The water-powered volcano demonstration is made in advance, using sand, hoses and a water balloon, representing the main components of all volcanoes. During the activity, students observe, measure and sketch the volcano, seeing how its behavior provides engineers with indicators used to predict an eruption.

- Abstract: Students learn about the causes, composition and types of volcanoes. They begin with an overview of the Earth's interior and how volcanoes form. Once students know about how a volcano functions, they learn how engineers predict eruptions. In a class demonstration, students watch and measure a mock volcanic eruption and observe the phases of an eruption, seeing how a volcano gets its shape and provides us with clues to predict a blast.

- Abstract: Volcanoes are big movers and shakers in the business of continually redesigning the Earth's landscape. With no concern for nearby people or ecosystems, volcanoes release toxic gases, climate-altering ash, lava and rock. How does this work? Are scientists getting better at predicting volcanic eruptions? How do areas recover after destruction?
