Introduction to Graphing GPS data | Lessons on Plate Tectonics
This activity emphasizes making graphs—in order to make interpreting graphs easier. Students graph data measuring how GPS stations move north or south and east or west. They begin by graphing fictitious data and progress to graphing data from several stations in the western United States. Eventually they graph north-south vs. east-west motion of a station in order to see that another purpose of plotting data is to make maps. They also develop intuition about vectors.

Taking the Pulse of Yellowstone's "Breathing" Volcano
In this activity, students learn about volcanism in Yellowstone National Park, focusing on its history of eruptions, recent seismicity, hydrothermal events, and ground deformation. They learn how scientists monitor ...

GPS Velocity Viewer
This interactive tool allows users to see GPS/GNSS-measured crustal motions around the globe in a wide range of reference frames. The default view shows horizontal motions in the North American reference frame but users can choose to add vertical motions, earthquakes epicenters, plate boundaries, volcanic centers, or other reference frames. The tool can also be used as an interface to learn GPS/GNSS station names and download time series data.
