How Do We Know Where an Earthquake Originated? part of EarthScope ANGLE:Educational Materials:Activities
Jeffrey Barker (Binghamton University) & Michael Hubenthal (IRIS)
Students use real seismograms to determine the arrival times for P and S waves and use these times to determine the distance of the seismic station from the earthquake. Seismograms from three stations are provided to determine the epicenter using the S – P (S minus P) method. Because real seismograms contain some "noise" with resultant uncertainty in locating arrival times of P and S waves, this activity promotes appreciation for uncertainties in interpretation of real scientific data.

Human Wave: Modeling P and S Waves part of EarthScope ANGLE:Educational Materials:Activities
IRIS (Incorporated Research Institutions for Seismology) and ShakeAlert
Lined up shoulder-to-shoulder, learners are the medium that P and S waves travel through in this simple, but effective demonstration. Once "performed", the principles of P and S waves will not be easily forgotten. This demonstration explores two of the four main ways energy propagates from the hypocenter of an earthquake as P and S seismic waves. The physical nature of the Human Wave demonstration makes it a highly engaging kinesthetic learning activity that helps students grasp, internalize and retain abstract information.

Earthquake Hazard Maps & Liquefaction: Alaska emphasis part of EarthScope ANGLE:Educational Materials:Activities
TOTLE (Teachers on the Leading Edge), CEETEP (Cascadia EarthScope Earthquake and Tsunami Education Program), EarthScope ANGLE, and ShakeAlert projects
Ground shaking is the primary cause of earthquake damage to man-made structures. This exercise combines three related activities on the topic of shaking-induced ground instability: a ground shaking amplification demonstration, a seismic landslides demonstration, and a liquefaction experiment. The amplitude of ground shaking is affected by the type of near-surface rocks and soil. Earthquake ground shaking can cause even gently sloping areas to slide when those same areas would be stable under normal conditions. Liquefaction is a phenomenon where water-saturated sand and silt take on the characteristics of a dense liquid during the intense ground shaking of an earthquake and deform. Includes Alaska and San Francisco examples.
