This Why Files short article discusses some new research on Yellowstone Caldera, a giant volcanic hotspot in Wyoming. Rock has been remelted inside the caldera. Using highly sensitive techniques to extract data from almost microscopic zircon crystals, two geologists at the University of Wisconsin-Madison found that over the past 2 million years, the giant Yellowstone volcano erupted at 700,000-year ...

This resource presents three examples of lava domes, from Alaska, Japan, and Saudi Arabia, along with a 3D simulated view of Mt. St. Helens' lava dome. A diagram shows the progressive growth of Mt. St. Helens' lava dome from 1980 to 1983. A link leads to a thorough explanation of dome-collapse pyroclastic flows (nuee ardentes) and another leads to a numerical program of lava dome growth.

This United States Geological Survey (USGS) website explains volcanic gases and their effects on the Earth and its life. The report discusses gases trapped in magma below the Earth's surface as the driving force of volcanic eruptions. Types of gases, such as sulfur dioxide and carbon dioxide, and their potential effects are described. A comparison of volcanic gas composition in three different volcano ... Full description.

This United States Geological Survey (USGS) fact sheet is designed to educate visitors about safety in preparation for visiting Kilauea Volcano in Hawaii. This volcano has been erupting almost continuously since 1983 and is noted for its approachable lava flows; however, it undergoes many changes that can be unpredictable and life threatening. Topics include volcanic hazards such as bench collapse, ... Full description.

In this activity, students match photographs of igneous rocks with descriptions of their formation. There are also two teacher demonstrations that will help students to identify pumice and volcanic ash with graded bedding. Other pictures and descriptions are of breccia, columnar jointing in a basaltic lava flow, coarse grained granite, and phenocrysts in a porphyry. At the end of the activity students ...

This article, from Earth: Inside and Out, provides insight into what scientists are learning about Mt. Rainier's volcanic past and future. It provides an overview of the nature of the work of Tom Sisson as a mountaineer and geologist with the Volcano Hazards Program at the United States Geological Survey, and the on-the-job hazards he faces. It explains how Sisson is creating a three-dimensional map ... Full description.
