See how a 3-Component seismogram records seismic-wave motion. [2:53]
Alaskan tectonics are dominated by Pacific-North American plate interaction. This animation discusses the range of tectonic activity from megathrust earthquakes to accretion of geologic terranes. [8:40]
Find out why faults don't just keep sliding past each other. [0:14]
How do the valleys form in a basin-range province? [0:33]
See how basin and range mountains and valleys form. [1:05]
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]
Animation demonstrates how seismic waves migrate away from an earthquake. [0:08]
See how to model differential friction along a fault. [2:30]
See a scientist talk about elasticity and brittle material using a yardstick as a mechanical analog for the lithosphere, and to show how stress is stored in-between tectonic plates. [1:57]
Visualize how a horizontal fault moves. [0:19]
This animation shows that GPS can record the movement of the leading edge of the overlying continental plate in a subduction zone. [0:48]
Animation shows how land jumps in an earthquake and how GPS can record the movement. [0:49]
Focusing on the Gulf of California Rift Zone, this animation depicts the evolution of the spreading ridge that marks the boundary between the Pacific and North American Tectonic Plates. [3:12]
Animation explores hotspot volcanism and offers a simple illustration of how this results in chains of volcanoes such as the Hawaiian Islands. [2:14]
This animation addresses regional and local tectonics, earthquake occurrences and historic earthquakes, crustal fault earthquakes (Kobe, 1995), megathrust earthquakes (Tohoku-Oki, 2011), and tsunamis. [10:04]
Earth's interior is broadly grouped into three main layers on the basis of chemical composition: crust, mantle, and core. An egg analogy is used to show relative thicknesses, and a Big Hunk analogy illustrates how a material of a single composition can be either brittle or ductile depending on temperature. [6:20]
This animation discusses the history of the discovery of the Mohorovicic Discontinuity, as well as the logic behind it. Spoiler Alert: It is about Snell's Law. [9:22]
Animation shows a comparison of the basic features of the Earth with the red planet, Mars. [2:49]
Studies of the rocks in New Madrid tell quite a story. This is an animation illustrating how the scenery changed over 500 million years. [0:54]
Using map view in concert with cross sections, this animation steps the viewer through both volcanic and simplified tetonic processes. [5:11]
