Some math is involved when trying to locate the epicenter. Today our focus was on calculating the "lag time" of the P and S-waves. We then used this info to find the distance on the time-distance graph.
Homework tonight! Complete Parts 1 and 2 on the Time Travel worksheet. I will help you with Part 3 in class.
Also trip money/slip was due today. If you did not turn it in and would like to go with us on 10/20 please see me!!!
