This is a lab to help students explore the triangulation method used to determine earthquake epicenters. I created this lab because I wanted a lab that very purposefully made students practice the analysis of seismogram data, calculate pertinent information such as "lag time" from P-wave and S-wave data and use triangulation to determine epicenter location. I wanted a lab that (a) focused on these skills and not other data (while interesting and important could also distract from the learning target) and (b) a lab that looked simple and pleasing to the eye. (If you're interested in also plotting earthquakes, CHECK OUT MY COMBO pack which includes this lab as well as my Plotting Earthquakes Lab a lab featuring current earthquakes - data updated every year!)
What you get:
*The lab which includes four complete sets of earthquake data (data, triangulation map, key). In other words, students will calculate the epicenter location for four different earthquakes.
*A set of student notes which explicitly show, step by step, how to use P and S wave arrival time with a P and S wave curve to calculate epicenter distance AND P and S wave travel time. With these notes I give example data sets for practice and I include a key.
*A suggested lesson plan to follow.
***A word about PRICE: This lab is top notch. I created the data in this lab, calculated all numbers and constructed all maps and keys to represent accurate seismic data in a clear and concise way.
