This animation shows how a GPS network throughout the Western United States, mainly composed of the EarthScope Plate Boundary Observatory operated by UNAVCO, measures regional water loss from drought. [.mp4]
This animation shows how GPS can help us measure changes in a glacier. [.mp4]
How does the land over a subduction zone move before, during, and after a great earthquake? Using GPS, we can watch the surface of the Earth deform in response to the drag of one tectonic plate going under another. This movement and deformation is visible data from EarthScope's Plate Boundary Observatory in the Cascadia region. [.mp4]
What makes for an effective earthquake early warning system? In this animation, we see why Japan's earthquake early warning system underestimated the magnitude of the March 11, 2011 Tōhoku event, leading to underestimates of the tsunami. The animation illustrates how by using GPS data, we could more effectively detect and describe a similar great earthquake along the Cascadia subduction zone. [.mp4]
The Geoscience Career Spotlight series highlights the variety of careers available to geoscience majors in addition to academia. These videos are produced by UNAVCO interns and are designed to be short enough to show in an undergraduate classroom without changing existing lesson plans.
5-minute Ignite talks on a variety of geodesy topics.
Animations and videos made by partners
This animation explains how geodesy is the science of where things are, where they have been, and where they are going. It illustrates practical uses of geodesy for mapping, navigation, surveying, measuring movements of the Earth’s crust, and changes in the height and shape of ice sheets.shape of the Earth.
Every minute of every day, the face of Earth changes - sometimes right before our eyes. Go inside tectonic events, watching earthquakes rumble, volcanoes explode, and land transformed.
