Videos

Short-segment video lectures to give rudimentary background information on the Earth and plate tectonics to teach how earthquakes happen and how they are studied. The video lecture series was intended for middle-school Earth-science teachers, but principles can be understood by the general public and can be used in introductory undergraduate classrooms.

Teaching Earth Science

Public Outreach

Robert Butler, a University of Portland environmental science professor, talks about the March 11, 2011 Magnitude 9.0 earthquake and tsunami that impacted Northern Japan.
 
This talk, in 4 parts, covers the Japan earthquake and how it can be compared to past and future Great earthquakes in the Pacific Northwest.

Earth and Plate Tectonics

Seismic Slinky: analogy for P & S Waves

Roger Groom, science teacher at Mount Tabor Middle School, Portland Oregon demonstrates how a slinky is a good analogy for P & S seismic waves. He also points out where the model fails to fully mimic seismic-wave behavior. Slinkies prove to be a good tool for modeling the behavior of compressional P waves and shearing S waves. We recommend reading about the behavior of seismic waves and watching animations on IRIS' pages to learn more about how the P, S, and surface waves differ from each other.

Elastic Rebound 1

Uses wooden yard stick to discuss the brittle and elastic nature of tectonic plates. Stress builds up in the earth and when overcome plates shift past each other creating earthquakes.
