Summary:Elastic waves that move through the Earth are called seismic waves. Want to study them more closely? SeisMac is a free application that displays the output from the Sudden Motion Sensor in recent Mac laptops as a real-time, three-axis, acceleration graph, or, more commonly, a seismogram. Once your class has received some instruction on seismic waves, the following activity can leverage SeisMac technology to help students understand how a seismometer records ground motions. Consider: What information does a threecomponent seismogram express? How are S and P waves identified on a seismogram? How do seismic waves travel through the Earth?
