Students learn what causes earthquakes, how we measure and locate them, and their effects and consequences. 11 minutes elapsed between the first P wave and the last measurable surface wave. Mark the first arrival of the swave on each seismogram. Students learn about the types of seismic waves produced by earthquakes and how they move through the Earth. When the tension becomes too great, the fault slips, causing an earthquake. Dochub is the best editor for changing your documents online.

Locating the epicenter of an earthquake worksheet answer key, locating the epicenter of an earthquake worksheet pdf, chapter 7 lab 1 locating epicenters answer key, how many seismographs are needed to locate the epicenter of an earthquake. What did it feel like? Through the online Earthquakes Living Lab, student pairs explore various types of seismic waves and the differences between shear waves and compressional waves. All rights reserved. Finding the epicenter worksheet answer key. Earthquakes occur along faults, which are cracks in the Earths crust that build tension. A seismograph is securely mounted onto the surface of the earth so that when the earth shakes, the entire unit shakes with it EXCEPT for the mass on the spring, which has inertia and remains in the same place.

Accessed December 11, 2013. http://en.wikipedia.org/wiki/Moment_magnitude_scale, Novak, Gary. Then do the same for the S-wave. They use three seismographs in a process called triangulation to determine earthquake epicenters. The earthquake occurred somewhere along that circle. Using historical seismographs, engineers forecast the strength or magnitude of earthquakes and make predictions and determine building codes and safety protocols. However, please review it for the specific setting, materials, students, and conventional safety precautions. 0000001746 00000 n
For example, the western United States has earthquakes more frequently and on a larger scale than the eastern part of the country. While earthquake locations are normally done with a computer that can quickly determine the paths of seismic waves through the Earth to many seismic stations, 15 Introduction to Geology Chapter Worksheet . View Notes - Locating_an_epicenter_activity from SCIENCE Earth Scie at Toms River High North. Adjust the timing to the class period, remembering that you will need time to introduce the investigation, clean up afterwards, and re-set up for the next class (if you are working with more than one class). Copyright USGS http://earthquake.usgs.gov/learn/kids/eqscience.php. During an earthquake, seismic waves are sent all over the globe.

S waves. ACTIVITY 4.2B Locating an Earthquake Figure 4.5 shows seismograms for the same earthquake recorded at three locations - New York, Nome, Alaska, and Mexico City. Describe the process of triangulation to locate an epicenter. The lag time for any Looking at the nomogram, students click on each location data point to see where the three lines intersect to read the estimated magnitude. Great exercise for Regents Earth Science. How are S and P waves used to determine how far away epicenters are? It is slower than the same earthquake's P wave and cannot travel through liquids.
