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 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.

Melting ice cubes part of Oceanography:Activities
Mirjam Glessmer, University of Bergen
Explore how melting of ice cubes floating in water is influenced by the salinity of the water. Important oceanographic concepts like density and density driven currents are visualized and can be discussed on the ...

Using Google Earth to measure seacliff erosion rates part of Oceanography:Activities
Alfred Hochstaedter, Monterey Peninsula College
This lab uses Google Earth to measure the rate of seacliff retreat. It touches upon coastal processes, natural hazards, and coastal management issues. The central focus of the lab is in the Monterey Bay area.

Learning About Marine Sediments Using Real Data part of Introductory Courses:Activities
Kristen St. John, James Madison University
This exercise set explores marine sediments using real core photos and composition data from the scientific ocean drilling programs DSDP, ODP, and IODP in an inquiry-based approach.

Sound and light in the ocean part of Oceanography:Activities
Lauren Sahl, Maine Maritime Academy
Light is our usual method for observing on land, but water quickly absorbs light making it less useful in the ocean. On the other hand, sound in water can travel long distances before it is absorbed to the point ...

Case Study: Coastal Stabilization Structures part of Oceanography:Activities
