Earthquake Basics Presentation
Robert Butler (ANGLE Project)
This lecture and associated animations give a strong introduction to earthquakes--including earthquake waves, magnitude, intensity, USArray seismic data, and resulting hazards such as landslides, liquefaction, and building failure. It also includes some information on seismically resilient building design. It uses Alaska as the case study site. A similar lecture featuring the USA's Pacific Northwest region is available from the Cascadia EarthScope Earthquake and Tsunami Education Program (CEETEP)

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

SeismicWaves Viewer & SeismicEruption Software
Roger Groom, Mt Tabor Middle School
This activity includes both the Seismic Waves Viewer and the Seismic Eruption software to help learners better understand earthquakes, volcanoes, and the structure of the Earth. Seismic Waves is a browser-based tool to visualize the propagation of seismic waves from historic earthquakes through Earth's interior and around its surface. By carefully examining these seismic wave fronts and their propagation, the Seismic Waves tool illustrates how earthquakes can provide evidence that allows us to infer Earth's interior structure. Seismic Eruption shows seismicity (earthquakes) and volcanic activity in space and time from 1960 to present. When the program is running, the user sees lights, which represent earthquakes, flashing on the screen in speeded-up time. The user can control the speed of the action. In addition, the program can show seismicity under Earth's surface in three-dimensional and cross-sectional views. Earthquakes can be selected by magnitude and volcanic eruptions can be selected by volcanic explosivity index. In this way, large earthquakes and large eruptions can be selected to emphasize how different types of plate boundaries are characterized by different magnitudes of earthquakes (e.g. no major or great earthquakes occur on spreading ocean ridges). This lesson plan was developed by , Portland Oregon. Students investigate how seismic waves travel through Earth's internal layers and bounce and bend at internal boundaries between mantle, outer core, and inner core.

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.

Exploring Tectonic Motions with GPS
Shelley E Olds, EarthScope Consortium
Learners study plate tectonic motions by analyzing Global Positioning System (GPS) data, represented as vectors on a map. By observing changes in vector lengths and directions, learners interpret whether regions are compressing, extending, or sliding past each other. To synthesize their findings, learners identify locations most likely to have earthquakes, and defend their choices by providing evidence based on the tectonic motions from the GPS vector and seismic hazards maps.

USArray Seismic Wave Visualizations: Educator Information
These animations show how the ground responds when seismic waves from worldwide earthquakes sweep across more than 400 sensitive seismograph stations of (USArray), the seismologic component of EarthScope. Each animation has a map of the active USArray grid at the time of the earthquake. These animations are a creative use of the data being received by this unusually dense array of monitoring stations that were deployed as a means to "image" the roots of our continent.

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.

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 ...

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.
