SeisMac Seismogram Modeling part of Cutting Edge:Geophysics:Workshop 07:Geophysics Activities
Use the freely-downloaded "SeisMac" program on a Mac laptop to demonstrated the differences between P, S, Rayleigh and Love waves. SeisMac is a free program that instantly turns a Mac laptop into a 3-component seismograph using the accelerometers built into the laptop. The activity works as a demo for large classes or a hands-on activity for small classes, and involves learning how to shake the laptop in different ways to recreate actual 3-component seismograms.
