HMK 1_Plate Boundaries: Present, future, & past
Brian Hampton, Michigan State University; , Michigan State University
This project builds on in-class exercises and lectures by having students learn to identify modern, future, and past plate boundaries. Students will use trends in topography, distribution of earth quake and ...

Analyzing Plate Motion Using EarthScope GPS Data
DATA: EarthScope GPS Data. TOOLS: Spreadsheet, Google Maps. SUMMARY: Learn how GPS monuments make precise measurements of Earth's surface. Graph motion data and map velocity vectors to explore tectonic motion and surface deformation in the Pacific Northwest.

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

Measure a Changing Volcano
This hands-on demonstration illustrates how GPS can be used to measure the inflation and deflation of a volcano. Volcanoes may inflate when magma rises closer to the surface and deflate when the pressure dissipates or after an eruption.

Field Trip Guide: The 1964 Great Alaska Earthquake and Tsunami--Consequences of Living on the Leading Edge in Alaska
Robert Witter (ANGLE Project)
This is a guide to a field trip that visits sites in Anchorage, Girdwood, and Whittier Alaska. The focus of the trip is the understand the science and societal impacts of the 1964 Alaska Mag 9.2 earthquake as well as the ongoing EarthScope research on geohazards to help us better plan for future events. Participants practice a tsunami evacuation walk as way to foster discussion of preparedness actions and challenges.

Alaska Earthquakes & Tsunami Presentation
Robert Butler (ANGLE Project)
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.

GRACE: Tracking water from space

This 7-minute video gives an overview of the GRACE (Gravity Recovery and Climate Experiment) satellites and explains the technique of using gravity to measure mass movement such changing as ice and ...

What is Geodesy?

Overview of what traditional geodesy is, including descriptions of geoid, ellipsoid, datum, gravity, and GPS (global positioning system). Appropriate for high school or lower division college ...

GPS data for educators

Looking for interesting data to use in your course? UNAVCO has worked with educators and scientists to identify GPS stations that illustrate various Earth science processes. The data are the same ...

Elevation correction and the geoid tutorial

The Earth is not a perfect sphere, but is instead more like a slightly squashed sphere called an ellipsoid. Because of this, GPS receivers must use a correction model (called a geoid) to calculate ...
