These resources are all related to earthquake and tsunami science, hazard, and preparedness. The materials featured here are those most strongly emphasized in CEETEP workshops. Some resources pertain to plate tectonics and earthquake faults in general but others are specific to the USA’s Pacific Northwest (Cascadia) and science from the EarthScope geophysics initiative.

Pacific Northwest Fault Block Model
Through this activity, learners can investigate the motions of crustal blocks in the Pacific Northwest and relate these to the tectonics of western North America. Paleomagnetic and GPS observations were used to determine how crustal blocks of this region slide past eachother. The resulting earthquakes that occur on crustal faults near or immediately beneath densely populated cities of Oregon, Washington, and British Columbia are a major risk. |

Introduction to Pacific Northwest Plate Tectonics, Earthquakes, and VolcanoesDocument 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. |

Animation: Types of Motion in a Subduction Zone
Recent data from the Pacific Northwest and other subduction zones show that there are 3 distinct areas of movement above a subduction zone: 1) constant inland movement above the locked plate edge, 2) see-saw pattern of back-&-forth movement above a zone that alternately locks then slips in a process called episodic tremor and slip, and 3) no movement far inland above the deeper part of the diving oceanic plate. |
|
Animation: Episodic Tremor and Slip (ETS)
This animation shows a close-up of the movement recorded at a GPS station over an ETS region of a subduction boundary. Here we see the station fixed to the ground which is moving northeast on a ~14-month cycle before sliding back accompanied by a gentle seismic shaking shown in the seismogram. Researcher hypothesize that subduction zones are at higher risk of earthquake rupture during periods of ETS. |
|
Animation: What GPS Tells us About Future Earthquakes
This animation compares the subduction zone east of Japan with a mirror-image subduction zone across the Pacific—the Cascadia subduction zone off the coast of the Pacific Northwest. Using GPS, we can watch the surface of the Earth deform in response to the drag of one tectonic plate going under another and clearly observe the deformation occurring in Cascadia that will inevitably lead to more megathrust earthquake and tsunami. |
|
Animation: GPS and Earthquake Early Warning Systems
What makes for an effective earthquake early warning system? With seismic data alone, we cannot determine the magnitude and rupture area of megathrust earthquakes as quickly and effectively as we can with the addition of GPS data. In this animation, we see why Japan's earthquake early warning system underestimated the magnitude of the March 11, 2011 Japan earthquake, leading to underestimates of the earthquake's effects, such as tsunami size. |

USArray Seismic Wave Visualizations Educator Guide
These animations show how the ground responds when seismic waves from worldwide earthquakes sweep across more than 400 sensitive seismograph stations of USArray, the seismologic component of EarthScope. The associated documentation support an educator in including this content in their class. |

Introduction to GPS (GPS “gumdrop” activity)
This activity allows learners to analyze high-precision GPS observations of deformation of the North American Plate in Cascadia. Learners analyze the rates of motion of three GPS receiving stations at different distances from the Cascadia subduction zone boundary and see how the slowly accumulating elastic energy will be released in the next Cascadia megathrust earthquake! |
Original Activity Instructions |
GPS Part 2 - Locked and Loading
This activity is an enhancement of the GPS Gumdrop activity. It is intended for educators who wish to provide their learners with a more complete spatial picture of deformation of the Pacific Northwest continental margin. |
Activity Instructions |
Episodic Tremor and Slip (ETS)
Through this activity, learners 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. |

GPS Cards
These simple cards showing annual GPS station movements along Cascadia over the last decade or more offer a excellent locally-based confirmation that the ground below the coastal Pacific Northwest is moving and more megathrust earthquakes will inevitably occur. |

Field trips can provide excellent opportunities for seeing evidence of past Cascadia earthquakes and tsunami, visiting EarthScope instruments measuring ground movement, learning about both the benefits and challenges of living in a geologically active region, and discussing opportunities for community hazard mitigation.
All CEETEP workshops include a field trip day during which participants visit sites featuring earthquake and tsunami geology and preparedness.
Virtual field experiences (VFE) offer a way to share field trip sites with learners unable to visit in person. VFEs have been prepared for two areas in coastal Cascadia (southwest Washington and northwest Oregon) that showcase evidence used to build our understanding of past earthquake/tsunami and GPS stations measuring ongoing deformation.
Organizations collaborating with CEETEP and/or working parallel on related aims of increasing earthquake and tsunami resilience provide an wealth of additional information and resources.
