Volcano Monitoring with GPS: Westdahl Volcano Alaska
Maite Agopian, EarthScope; Beth Pratt-Sitaula, EarthScope
Learners use graphs of GPS position data to determine how the shape of Westdahl Volcano, Alaska is changing. If the flanks of a volcano swell or recede, it is a potential indication of magma movement and changing ...
Alaska GPS Analysis of Plate Tectonics and Earthquakes
Beth Pratt-Sitaula, EarthScope
This activity introduces students to high precision GPS as it is used in geoscience research. Students build "gumdrop" GPS units and study data from three Alaska GPS stations from the Plate Boundary Observatory network. They learn how Alaska's south central region is "locked and loading" as the Pacific Plate pushes into North America and builds up energy that will be released in the future in other earthquakes such as the 1964 Alaska earthquake.
