Expert Answer. Students also investigate which structural designs are most likely to survive an earthquake. 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. 0000003966 00000 n Specifically, seismographs make recordings (seismograms) of the seismic waves generated from earthquakes, providing engineers and other researchers with data that they use to make predictions about future earthquakes. Several thousand seismographs exist at locations around the planet, continuously measuring abnormalities in the Earth's movement. Pwaves have the greatest velocity and reach theseismic station first.

The farther away the epicenter is, the greater the difference . Moment magnitude scale. What data is used to determine magnitude? A single recording station can only calculate distance, but not direction; to cover all possibilities, a complete circle is drawn around that station. For upper grades, have students work individually, do two of the three seismic area tutorials, and look up historical earthquakes to learn their magnitudes, and make data tables or graphs with this information. triangulation: A method to determine exactly where an earthquake originates. To accurately locate an earthquake epicenter, records from three. distance = travel time for S waves 0000004457 00000 n The process is called triangulation. The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people. minutes? If the lag time were measured at a location closer to the epicenter, The period of a wave is the time between two adj, How does the period of the P waves compare to t. Use data from seismograms to locate the epicenters of earthquakes. Success is figuring out that the epicenter is just off the coast of Chile, where the three circles intersect. Using the real-world data in the living lab enables students and teachers to practice analyzing data to solve problems and answer questions, in much the same way that scientists and engineers do every day. It's a logarithmic scale from 1 to 10 with each succeeding level representing 10 times as much energy as the last. This section explains what earthquakes and faults are and what causes earthquakes.
