Visit an active volcano site to find out the connection between the movement of the Earth's plates and the processes deep within the Earth's interior. [58:23]

Benjamin Drake, almost a contemporary of Tecumseh, offers this biography first published in Cincinnati in 1841. Page images are arranged here, with the added bonus of search capablility.

This site is an online library of information about civil engineering.

Presents information and data on all aspects of the geography, natural resources, and climate of Texas, including natural disasters and extreme weather events.

Discover the ways in which the Earth's surface is always changing and what causes those changes through reference materials and a collection of activities.

Earthquakes create seismic waves that travel through the Earth. By analyzing these seismic waves, seismologists can explore the Earth's deep interior. This fact sheet uses data from the 1994 magnitude 6.9 earthquake near Northridge,...

Multi-lesson activity where learners will work with data from a seismic wave model in a GIS (geographic information system) program. They will examine maps, select data, and produce graphs to explore variations in seismic wave velocities...

In this activity, students will observe and understand the basic kinematics of plate movement, how oceans are formed during continental rifting, and the relationship between plate geometry and tectonic data such as earthquakes, heat...

This lesson is a writing assignment focussed on the use of data to support the theory of plate tectonics. It includes a scoresheet that was created for a calibrated peer review assignment. The assignment directs students to determine the...

This article in the Journal of Geoscience Education describes a classroom exercise based on four world maps containing earthquake, volcano, topographical and seafloor age data. Students participate in this exercise by using a "jigsaw"...

Learn about geohazards such as mudslides, earthquakes, and outburst floods that can be found in National Parks.

Explore current new articles focusing on STEM topics. Learn about 3D printing, supermoon, earthquakes, and much more.

Since 2001 the USGS has been monitoring the earth's surface in Yellowstone to understand the activity of volcanoes and earthquakes. This resource recognizes the Dotsero Volcanic Center.

This national organization is responsible for coordinating work efforts to prevent crisis situations (volcanic eruptions or flooding, for example), and responding to these emergencies when they arise. Their Web site contains links to...

The Japanese nuclear plant has to begin a lengthy decommissioning project. Concerns are growing over the radiation levels that have been rising since the plant's meltdown after the 2011 earthquake and tsunami.

Delve into the structure of the Earth to learn what causes earthquakes, volcanoes, and more.

Scientists have a fairly good understanding of how the plates of the Earth move and how such movements relate to earthquake activity. Most movement occurs along narrow zones between plates where the results of plate-tectonic forces are...

The vast majority of earthquakes and volcanic eruptions occur near plate boundaries, but there are some exceptions. Learn here all about mantle thermal plumes.

As an overview of the online exhibit on earthquakes, this site discusses the various sections inside the Earth. The crust, the mantle, and the core are each individually discussed.

Have you ever noticed how some of the continents and land masses of Earth seem to fit together like pieces of a puzzle? This unit is designed to help you understand why continent shapes appear that way. In addition you will learn how...

Your research team has found a prehistoric virus preserved in the permafrost and isolated it for study. After a late night working, you're just closing up the lab when a sudden earthquake hits and breaks all the sample vials. Will you be...

See a map of the Panama-Pacific International Exposition in San Francisco in 1915. An interesting hyperlink shows a map of the same area and the buildings damaged by the earthquake in San Francisco in 1989.

The USArray Ground Motion Visualization (GMV) is a video-based IRIS DMS product that illustrates how seismic waves travel away from an earthquake location by depicting the normalized recorded wave amplitudes at each seismometer location...

Students use the IRIS Earthquake Browser to investigate well-known examples of some plate boundaries.
