Episodic tremor and slip: The Case of the Mystery Earthquakes | Lessons on Plate Tectonics
Shelley Olds, UNAVCO
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.
Bomb Cyclones - They're Explosive!
Jacqui Jenkins-Degan, Marine Technology Program, Cape Fear Community College
Storms can have devastating impacts on coastal communities. Typically, tropical storms like hurricanes get the most attention, but there are other types of storms that occur at more northern latitudes that can be ...
Rally Speeches for Coastal Optimism
Laura Guertin, Penn State Brandywine
Storytelling is an effective way to communicate what is happening along our local-to-international coastal zones. However, most of the stories students hear are ones of "doom and gloom." Therefore, ...
Population & Community Ecology
Cascade Sorte, University of California-Irvine
Students in a Population and Community Ecology class participate in coastal marine research focused on understanding factors determining population sizes and community interactions, particularly in the context of species that appear to be shifting their ranges with climate change. Students participate in all aspects of the research from making observations and collecting data in the field to defining questions, stating hypothesis, designing and completing statistical analysis, and interpreting and presenting results. The outcomes are a research proposal, research paper, and poster presentation. All are intended to be at a level appropriate for use as a writing sample or presentation at undergraduate conferences. Results are incorporated into the ongoing research project led by the course instructor and graduate student teaching assistant.
Alaska Earthquake Hazard Inventory & Mitigation Planning
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)
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.
Unit 8: Thermohaline Circulation
David Bice, Pennsylvania State University-Main Campus
In this module, students first review some background material on density-driven deep currents in the oceans, and then create a STELLA model of the thermohaline circulation in the North Atlantic Ocean. The model ...
Justice, Power, and Activism: What the Goldman Environmental Prize Winners Teach Us About Resilience and Democracy
Jason Lambacher, University of Washington-Tacoma Campus
This activity is a set of student-centered exercises that enable students to learn about the individual stories of Goldman environmental prize winners, the activism and organizing that grounds their work, and the underlying political and social contexts from which their struggles emerge. The lesson inspires critical reflection about justice, power, and democracy in green politics, and encourages ways to make personal connections to activism and environmental work.
Unit 2: Application of Concepts to Case Studies
Patricia Stapleton, Worcester Polytechnic Institute; Lisa Doner, Plymouth State University; Lorraine Motola, Metropolitan College of New York
In Unit 2, students apply and evaluate foundational concepts about storm hazards and risk in the context of two cases studies: Superstorm Sandy (2012) and the Storm of the Century (1993). Through different ...
Unit 3: Culmination of Module in Town Hall Meeting
Patricia Stapleton, Worcester Polytechnic Institute; Lorraine Motola, Metropolitan College of New York; Lisa Doner, Plymouth State University
Over the course of one week, students will apply and evaluate concepts in the context of their local community, culminating in the formulation and evaluation of Hazard Mitigation Plan recommendations presented in ...
