Copyright USGS http://earthquake.usgs.gov/learn/kids/eqscience.php. 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. Details. from the epicenter will be 14 8. THREE SEISMOGRAMS Seismogram A - New York, NY 1 minute 1. U.S. Geological Survey, U.S. Department of the Interior. If a quake is near the seismograph, the S-waves arrive shortly after the P-waves. Today, most seismologists no longer follow Richter's original methodology because it does not give reliable results when applied to stronger earthquakes and it was not designed to use data from earthquakes recorded at epicentral distances greater than ~600 km. Students first triangulate the location of an earthquake's epicenter, then calculate its magnitude. 1) Identify the general term for waves released from an earthquake. Three seismographs are needed. We additionally manage to pay for . When the tension becomes too great, the fault slips, causing an earthquake.

The spot where those three circles intersect is the epicenter (Figure 13.12). 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). earthquake though). Using historical seismographs, engineers forecast the strength or magnitude of earthquakes and make predictions and determine building codes and safety protocols.
