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.

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.

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.
