This PDF provides a brief (12 page) introduction to regional plate tectonics, earthquakes, and volcanoes of the Pacific Northwest. The focus is mainly on the subduction zone (coast to Cascade Mountains) because that is where most of the earthquakes and volcanoes occur, and where tsunamis can be generated. This information was gathered and repurposed by Jenda Johnson and Bob Butler from the Pacific Northwest Seismograph Network (www.pnsn.org/), the U.S.

This file is a zipped collection of PowerPoint Presentation along with associated QuickTime animations. The PowerPoint is 36 slides on the Japan magnitude 9.0 earthquake and resulting tsunami with comparisons to Cascadia past and future great earthquakes and tsunamis. You are welcome to download the zipped archive and use any or all elements for your own educational purposes. Please acknowledge Teachers on the Leading Edge as the source.

Roger Groom, Mt Tabor Middle School, developed this activity while working with Becca Walker at UNAVCO in Boulder, Colorado. Through this activity, students can learn about an exciting discovery made possible by invention of high-precision GPS receivers and deployment of these receivers across the Pacific Northwest. This activity can be used to illustrate how invention of new technologies can lead to new scientific discoveries that would have been impossible without the new instruments; a good lesson in how science works.

This PowerPoint presentation contains GPS time series plots for 10 Plate Boundary Observatory stations across the states of Washington and Oregon. These include four coastal stations (Neah Bay, Pacific Beach, Tillamook, and Newport); three stations in the urban corridor (Tumwater, Kelso, and Corvallis); and three stations located east of the Cascade Mountains (Othello, Wasco, and La Grande). Line fits to the north and east components of motion of these stations are shown and rates of north and east motion are provided for each station.

The basics of reading GPS time series plots are explained in this step wise, thorough, and nicely illustrated PowerPoint presentation developed by Shelley Olds at UNAVCO. This PowerPoint presentation can be used to support the Cascadia GPS Gumdrop Lesson Plan or simply for additional information for the teacher.

This PowerPoint presentation covers the basics of Cascade volcanoes and volcanic hazards. The presentation was developed by Beth Pratt-Sitaula and Jenda Johnson with assistance from Denise Thompson. Before veiwing this PowerPoint presentation, viewers are encouraged to review the PDF Introduction to Pacific Northwest Plate Tectonics, Earthquakes, and Volcanoes under the Cascadia Earthquakes and Tsunamis topic.

This PowerPoint presentation covers basics of Cascadia earthquakes and tsunamis. Before veiwing this PowerPoint presentation, viewers are encouraged to view the PowerPoint presentations under the Introduction to Plate Tectonics and Earthquakes topic.

You are invited to download and modify this PowerPoint presentation for your own classroom teaching.

This PowerPoint presentation covers basics of tsunami hazards using the December 2004 Indian Ocean tsunami as an example. Before veiwing this PowerPoint presentation, viewers are encouraged to view the PowerPoint presentations on Plate Tectonics and Earthquake Seismology available under the Introduction to Plate Tectonics and Earthquakes topic. 

This guide is an outline of two PowerPoint presentations ("Plate Tectonics" and "Earthquake Seismology") that provide an Introduction to Plate Tectonics and Earthquakes. The PDF contains links to teaching resources posted on the TOTLE web site and, in a few cases, to teaching resources on other web sites. The outline format is effective for users who want a quick overview of TOTLE resources or already know of particular resources they wish to download.

This PowerPoint presentation covers basics of earthquake hazards, damage to structures due to earthquakes, and building designs that can make structures earthquake resistant.
