It's a logarithmic scale from 1 to 10 with each succeeding level representing 10 times as much energy as the last. In Figure 13.9, there is an example seismogram from a station that includes a minor earthquake. Direct students to finish the activity by completing the. Earthquakes Living Lab: Finding Epicenters and Measuring Magnitudes ActivityWorksheet Example Answers 4 now big earthquakes are measured using the moment magnitude scale; both scales essentially rank the power (energy release) of the earthquake. For example, the western United States has earthquakes more frequently and on a larger scale than the eastern part of the country. S-P interval: The time interval between the arrivals of P and S waves. The magnitude is the logarithm of the amplitude of the ground wave. The Richter scale was created in the 1930s to assign a single number to quantify the energy released during earthquakes. (Listen to student ideas.) Activity4:LocatinganEarthquakeEpicenter Objectives:Ifyoucompletealltheproblems,youshouldbeableto: Identif The distance is in kilometers. Run through the investigation yourself and record the data, just to see how long it takes. Make arrangements so that each student group has a computer with Internet access. A circle with a radius of the distance to the quake can be drawn. Success is figuring out that the estimated magnitude is 5.9. Describe the logarithmic nature of the earthquake magnitude scale. While no one can predict earthquakes, knowing the intensities, frequencies and locations of past earthquakes and fault planes helps us to better anticipate the locations and forces to expect, so we can do our best to prepare our communities and infrastructure to withstand them safely. Using online resources and simulations available through the Earthquakes Living Lab, students explore the consequences of subsurface ground type and building height on seismic d Seismographs are measuring devices designed by engineers and used by researchers to determine the locations and magnitudes of earthquakes. 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. graph. directly above it on the surface of the earth is called the epicenter. 87 0 obj

Practice with Triangulation: Locating an earthquake epicenter. 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?" 4. Thus technology use varies from region to region and over time. At least 3 earthquake recording stations are required to find the location of the earthquake epicenter. HTAn hbbd``b`$C`q9 X_$_g`bdxc`X Apr 8, 2020 One seismogram indicates the distance to the epicenter. Make an overhead copy of each of the handouts. Wikipedia, The Free Encyclopedia. If you draw a circle on a map around three different seismographs where the radius of each is the distance from that station to the earthquake, the intersection of those three circles is the epicenter.

PDF Page - 1 Lab 08 - Seismology - Locating the Epicenter of an Earthquake This is determined by the P-and S-wave arrival times. Using 3 seismograms the students will be able to triangulate the epicenter of an earthquake. Must engineers be content with mitigating disasters, instead of preventing them? Success is figuring out that the epicenter is just off the coast of Chile, where the three circles intersect.
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. To locate the epicenter of the earthquake, seismologists use the . Assess their understanding based on the thoroughness of their answers. xb``d``Id`a`Ab@_ :iWGi>|q` Activity 4: Locating an Earthquake Epicenter, The three basic types of seismic wave generated by an earthquake at its focus are P, waves, Swaves, and Surface waves.
