Locating Earthquakes
Today in class we:
Discussed how seismographs can teach us about the magnitude of the Earthquake and our distance from its epicenter.
Discussed and practiced using triangulation technique to locate an Earthquake's epicenter using 3 data sets from seismographs
Began work on Earthquake Shake Lab
Homework:
due Wednesday: You and your group should have a drawing of your earthquake resistant building completed and ready to build
due Friday: Earthquake Review Sheet (see sidebar for downloadable copy)
