A cow and a tree in this narrated cartoon for fun and to emphasize that seismic waves traveling away from an earthquake occur everywhere, not just at seismic stations A, B, C, and D. A person would feel a large earthquake only at station A near the epicenter. Stations B, C, D, and the cow are too far from the earthquake to feel the seismic waves though sensitive equipment records their arrival.
This companion to the animation “Four-Station Seismograph network” shows the arrival of seismic waves through select wave paths through the Earth (P and S waves) and over the surface of the Earth. The movement at distant stations occurs at a microscopic scale. While that doesn’t result in noticeable movements of the buildings, the arrivals are recorded on sensitive seismometers.
Have your pair group defined for the Earthquake packet. We will be working in groups of two, no more, no less. You should come in knowing who you will be working with for the upcoming classes.
