Unit 6: Applying GPS strain and earthquake hazard analyses to different regions
Students select their own set of three stations in an area of interest to them, conduct a strain analysis of the area between the stations, and tie the findings to regional tectonics and societal impacts in a 5–7 ...

Unit 4: GPS and infinitesimal strain analysis
Students work with GPS velocity data from three stations in the same region that form an acute triangle. By investigating how the ellipse inscribed within this triangle deforms, students learn about strain, strain ...

Unit 3: Getting started with GPS data
This unit provides essential background information on GPS (global positioning system) and reference frames. Students learn how to access GPS location and velocity data from the Network of the Americas (NOTA). They ...

Unit 5: 2014 South Napa Earthquake and GPS strain
The 2014 South Napa earthquake was the first large earthquake (Mag 6) to occur within the Plate Boundary Observatory GPS network (now Network of the Americas- NOTA) since installation. It provides an excellent ...

Unit 2: Mashing it up: physical models of deformation and strain
Students gain an intuitive understanding of strain and deformation through a series of physical model activities using everyday materials such as bungee cords, rubber bands, fabric, index cards, silly putty, sand, ...

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.

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.

Alaskan Volcanoes & Hazards Presentation
This lecture and associated animations give a basic introduction to Alaskan volcanoes, volcanic hazards, and volcano monitoring.

Alaska Earthquakes & Tsunami Presentation
This lecture and associated animations delve in more deeply to the topic of Alaskan earthquakes and tsunami along with their causes and variability. It also draws on EarthScope GPS and seismic data to show how we can study earth processes to better understand Alaskan geohazards. It highlights case study sites of Whittier and Seward during the 1964 Alaska Mag 9.2 earthquake to show how differences in location, topography, and land use can lead to different tsunami experiences in different communities. give a good introduction to tsunami produced by earthquakes and landslides. It includes information on how they are generated and why there can be great variability between tsunami characteristics--even for earthquakes of similar size. The lecture describes tsunami generated by the in particular depth.
