This learning video uses a simple analog setup to explore why earthquakes are so unpredictable. The setup is simple enough that students should be able to assemble and operate it on their own with a teacher's supervision. [22:48]

In this video adapted from Alaska Sea Grant, discover why multiple tsunamis resulted from the Great Alaska Earthquake of 1964. Essay, discussion questions, and links to related material included.

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...

In this video segment adapted from NOVA, a geologist digs a trench along the San Andreas Fault to reveal three thousand years of earthquake history. Information from the layers of sediment may help geologists to predict earthquakes.3m 19s

Understand how energy disperses during an earthquake. This brief video will illustrate the theory of elastic rebound. [:25]

This animation shows both the movement of the three basic waves (P, S, and surface) and the effect of the waves on a building. It emphasizes that seismic waves traveling away from an earthquake occur everywhere, not just at seismic...

A video lecture that introduces a technique that can be used to make buildings earthquake-resistant. The instructor demonstrates and explains how to use simple materials to build a shear wall for a building. [9:15]

A video lecture that looks at what factors impact on the amount of damage that is caused by an earthquake. These depend on the intensity of the vibrations and the methods of construction used in the buildings. [6:05]

Animation explores how an earthquake early warning system works and shows how ground motion, measured by GPS, can enhance earthquake early warning. [6:57]

Review a video that introduces geologic evidence of unique megathrust earthquakes in the Pacific Northwest based on oral history, radiocarbon dating Tree-ring analysis as well as Samurai records dating back to the beginning of the...

Investigate what GPS can do to help study and predict future earthquakes. [4:12]

A video illustrates the concern scientists have over an inevitable megathrust earthquake due to the stress building between the Juan de Fuca and North American plates. Be sure to look at the additional resources found under the video...

Plate tectonics shift all over Earth. This video illustrates what happened in Pakistan in 2013. [1:59]

A detailed video featuring the challenges of western South America and why it is such a hot spot for earthquakes. [10:16]

A collection of seismic events recorded near Mount Saint Helens. The seismographs located at stations record seismograms like what are shown here. [2:10]

A video detailing the severe danger of megathrust earthquakes. These are known as the most powerful earthquakes on earth. [5:43]

This video segment adapted from Discovering Women uses animations to introduce the theory of plate tectonics and to explain why earthquakes occur and how continents form. 2m 21s

This video adapted from the Valdez Museum & Historical Archive, explores what happened during the Great Alaska Earthquake of 1964 through original footage, first-person accounts, and animations illustrating plate tectonics.

This video segment adapted from NOVA uses historical illustrations, photographs, and animations to explain how seismographs work, the difference between P and S waves, and the Richter scale.

Is it possible to predict earthquakes? While one researcher says radon readings gave early clues that a 6.3 quake in Italy, other earthquake experts aren't so sure. [7:5]

In this video students will discover what it means to be a seismologist [3.34]

Animated illustration shows the top and cross-section views of foreshocks that precede an earthquake, the mainshocks, and the aftershocks that follow the quake.

This lesson introduces and explores the Pacific Ring of Fire. It is 1 of 3 in the series titled "Geology: Pacific Ring of Fire."

This lesson introduces the plate tectonics of the world and discusses their effects on the earth. It is 2 of 3 in the series titled "Geology: Plate Tectonics."
