Tectonic Plate Movement in Alaska

In this video adapted from KUAC-TV and the Geophysical Institute at the University of Alaska, Fairbanks, learn how mountains, volcanoes, and earthquakes result from plate tectonics. Animations illustrate how the subduction of the Pacific plate under the North American plate and the collision of the Yakutat block builds mountains, such as the Wrangell and St. Elias Mountains. In addition, observe how technology (such as seismometers, satellites, and the Internet) helps scientists study the movement of Earth's crust, and learn about the surprising finding that there are still aftershocks being measured decades after the 1964 earthquake.

This video is available in both English and Spanish audio, along with corresponding closed captions.

This media asset was adapted from "STEEP: Saint Elias Erosion and Tectonics Project" by KUAC and Geophysical Institute of the University of Alaska, Fairbanks.
