The nations most famous fault is the San Andreas Fault, which runs along a north-south trend in southern California, and happens to run directly through Los Angeles. 9 - 0000004769 00000 n Earthquakes occur along faults, which are cracks in the Earths crust that build tension. (Grades 6 - 8). What is the time lag for the Seattle, Washington, seismic station? Why might the triangulation method not always produce an exact point (other than your measurement errors)? You learned that seismologists determine the distance to the earthquake epicenter using the difference between S and P wave arrival times. 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. The time Place a ruler (or straight edge) on the chart between the points you marked for the distance to the epicenter and the amplitude. Epicenter is the location on the surface of the Earth directly above where the earthquake starts. (Source: USGS, Wikipedia). Today we will be using a traveltime graph, where the vertical separation between, the P and S curves is equal to the difference in the arrival times between the Pwave, and Swave.

An earthquake is what happens when two blocks of the earth suddenly slip past one directly above it on the surface of the earth is called the epicenter. Learn from this informative and clear video.Brought you by award-winning Once each student has constructed his or her circle on the map, mark with an X, the epicenter of the earthquake. 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. Zip. So next, students compute the magnitude of this same earthquake by looking at the three simplified seismograms again, but this time selecting each's maximum S wave amplitude (height).
