This video segment adapted from NOVA tells the tragic story of two Japanese seismologists who disagreed about the threat of earthquakes in the early twentieth century. Today, seismologists in California offer residents a probability of risk that an earthquake might occur.

This video excerpt from NOVA explains the concept of plate tectonics and how it causes earthquakes.

In this lesson, students explore the causes of earthquakes and their impact on the geology of an area and on human societies. They begin by looking at the role tectonic plates play in creating the forces that cause earthquakes, to help them understand why earthquakes occur when and where they do. Hands-on activities illustrate how rocks can withstand a certain amount of stress, but that every material has its breaking point. When rocks break underground, an earthquake occurs. In the last section, students explore the impact earthquakes have on humans and look at the efforts scientists are making to better understand and predict these sometimes deadly events.

In this video from QUEST produced by KQED, find out how San Francisco Bay Area scientists are working to help predict when the next big one will hit.

In this video segment adapted from NOVA, animations are used to show how the hills around Los Angeles were formed by earthquakes at small thrust faults that extend outward from the larger San Andreas fault.

The history of earthquakes in the San Francisco Bay area is plotted on a digital map and analyzed in this video segment adapted from NOVA.

This video segment adapted from A Science Odyssey uses animation and archival footage to provide an overview of the theory of plate tectonics.

Using animations to illustrate the theory of plate tectonics, this video segment adapted from Discovering Women takes you to Lake Mead, Nevada, to see visual evidence of how plate movement has been stretching the North American continent. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

This video segment adapted from NOVA uses animation to show the relationship between the movement of a tectonic plate and whether volcanoes on the Hawaiian Islands are active or dormant.

This video segment from IdahoPTV's D4K presents the types of rocks, how they are formed, what they are made of and how they are classified.

Understand what happens when lava meets the ocean in this video from Nature.

In this lesson, students will identify methods for detecting and locating earthquakes, utilizing excerpts from the Nature episode titled “Can Animals Predict Disaster?”

In this video adapted from KUAC-TV and the Geophysical Institute at the University of Alaska, Fairbanks, learn how tectonic plate movement is responsible for building mountains, such as the Wrangell and St. Elias Mountains.

This interactive activity produced for Teachers' Domain shows the relationship between tectonic boundaries and the locations of earthquake events and volcanoes around the world.
