Episodic tremor and slip: The Case of the Mystery Earthquakes | Lessons on Plate Tectonics part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
Earthquakes in western Washington and Oregon are to be expected—the region lies in the Cascadia Subduction Zone. Offshore, the Juan de Fuca tectonic plate subducts under the North American plate, from northern California to British Columbia. The region, however, also experiences exotic seismicity— Episodic Tremor and Slip (ETS).In this lesson, your students study seismic and GPS data from the region to recognize a pattern in which unusual tremors--with no surface earthquakes--coincide with jumps of GPS stations. This is ETS. Students model ductile and brittle behavior of the crust with lasagna noodles to understand how properties of materials depend on physical conditions. Finally, they assemble their knowledge of the data and models into an understanding of ETS in subduction zones and its relevance to the millions of residents in Cascadia.

Be Smart, Be Prepared! Planning an Emergency Backpack part of EarthScope ANGLE:Educational Materials:Activities
Bonnie Magura (Portland Public Schools), CEETEP (Cascadia EarthScope Earthquake and Tsunami Education Program), and ANGLE Project
Participants learn what to do before, during, and after a potentially damaging earthquake. They brainstorm valuable components for an emergency supplies backpack and then present on their ideas. The primary resource is the booklet Are you prepared for the next big EARTHQUAKE in Alaska?

Alaska Earthquake Hazard Inventory & Mitigation Planning part of EarthScope ANGLE:Educational Materials:Activities
Bonnie Magura (Portland Public Schools), CEETEP (Cascadia EarthScope Earthquake and Tsunami Education Program), and ANGLE Project
In this two-part activity, students/participants first: - Complete a Hazard Inventory for their city or area of interest in the event of a magnitude 7 or larger earthquake and tsunami. - Identify what critical structures and infrastructure will be affected. Then: - Write a summary statement assessing strengths and vulnerabilities of essential services or infrastructure. - Propose actions for mitigating vulnerabilities. - Create an Action Plan to address identified needs.

Tsunami Vertical Evacuation Structures (TVES) part of EarthScope ANGLE:Educational Materials:Activities
Bonnie Magura (Portland Public Schools), Roger Groom (Mt Tabor Middle School), and CEETEP (Cascadia EarthScope Earthquake and Tsunami Education Program)
Students learn about tsunami vertical evacuation structures (TVES) as a viable solution for communities with high ground too far away for rapid evacuation. Students then apply basic design principles for TVES and make their own scale model that they think would fit will in their target community. Activity has great scope for both technical and creative design as well as practical application of math skills. Examples are from the Pacific Northwest, USA's most tsunami-vulnerable communities away from high ground, but it could be adapted to any region with similar vulnerability.

Tsunami Early Warning Demonstration part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
This hands-on demonstration illustrates how instruments can be used to warn people of a tsunami. The same principles can be applied to earthquake early warning. With an older audience, this is a demonstration that can be used to start a conversation. With a younger audience, this activity is a game.

Identifying Tsunami Sand in Salt Marsh Stratigraphy part of Teaching Activities
Erin Peck, Oregon State University
Through a hands-on activity using salt marsh sediment cores from Pacific Northwest estuaries, students will learn how these environments record the history of earthquakes and tsunami. Students will analyze the ...

Investigating Factors That Affect Tsunami Inundation part of EarthScope ANGLE:Educational Materials:Activities
Bonnie Magura (Portland Public Schools), Roger Groom (Mt Tabor Middle School), and CEETEP (Cascadia EarthScope Earthquake and Tsunami Education Program)
Learners modify elements of a tsunami wave tank to investigate the affect that near-coast bathymetry (submarine topography) and coastal landforms have on how far a tsunami can travel inland. Damaging tsunami are most commonly produced by subduction zone earthquakes, such as those that occur in Alaska.

Making Community Connections to Co-learn about Earthquakes part of EarthScope ANGLE:Educational Materials:Activities
Jennifer Pickering
Many people live in regions prone to earthquakes, tsunamis and volcanic eruptions, but the hazards and risks inherent in our communities may be very different. Making connections with learners from another location is a great way to share knowledge and practice science communication skills. Video conferencing applications like Zoom and Skype make it possible to connect with learners anywhere in the world. This activity provides a simple protocol, and a form for submitting a request to connect with a classroom teacher in Anchorage, Alaska.

The Waves and Tsunamis Project part of NAGT:Our Resources:Teaching Resources:Teaching Materials Collection
, Woods Hole Oceanographic Institution
How is a tsunami like a wave on a string? We assemble rubber bands, paper clips and washers into strings with various mass distributions to observe the effects on wave characteristics. The project is supplemented ...
