Finding the Epicenter Determine the epicenter distance from three different seismographs. Why might the triangulation method not always produce an exact point (other than your measurement errors)? activity illustrates how the epicenter of an earthquake is found. It travels faster than the same earthquake's S wave (almost double the speed) and is similar to sound waves. 0000002507 00000 n

Quick Tips. The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people. Use Figure 4.5 and the travel-time graph in Figure 4.4 to determine the distance between each station and THREE SEISMOGRAMS the epicenter. Triangulation is required to determine exactly where it happened. It is slower than the same earthquake's P wave and cannot travel through liquids. Section 8.1 What Is an Earthquake? As you may know, people have look numerous times for . Review their answers to assess their base knowledge of the subject matter. H\0y within type by subtype, then by grade, etc. What is an earthquake? Before going to the classroom, you will need to: Provide each student, with the following: Earthquakes occur every day all over the United States and all over the world. The time Direct student pairs to independently complete the tutorial/simulation to find an epicenter location via the triangulation method and compute the earthquake magnitude: The simulation directs students to look at three simplified seismograms from seismic stations in Chile (Talca, Santiago, Osorno) and select the correct measurements of the S-P intervals. 0000004769 00000 n

To make a magnitude determination, two measurements are needed: the S-P interval (already determined earlier in the tutorial) and the maximum amplitude of the seismic waves.

The epicenter is the point directly above it at the surface of the Earth. distance = travel time for S waves Moment magnitude scale. Thus, the Richter scale is used for measuring small earthquakes (3.5 M or less), while the moment magnitude scale is used for measuring stronger earthquakes (3.5 M or higher).

Mark the first arrival of the swave on each seismogram. Shear wave from earthquake, moving slower than primary waves, through solid material only. When the tension becomes too great, the fault slips, causing an earthquake. The period of a wave is the time between two adjacent wave peaks. For lower grades, just introduce the concepts of triangulation and the magnitude scale; a thorough understanding of P and S waves is not vital. 0000002840 00000 n
Earthquakes occur along faults, which are cracks in the Earths crust that build tension. Then locate and click the link in the center of the page under the question: "How is an earthquake epicenter located and how is magnitude determined"? (Grades
By looking at the time between the arrivals of the P- and S-waves, one can determine the distance to the earthquake from that station, with longer time intervals indicating longer distance. P and Swaves are body waves and travelthrough the interior of the earth. The point of origin of an earthquake is called its focus and the point on the Earth's surface directly above the focus is the epicenter. Thanks for your feedback!
