Mapping the history of natural hazards in a region, combined with an understanding of related geologic forces can help forecast the locations and likelihoods of future events. 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. Have students turn in their answers for the Explain portion of the worksheet. These distances are determined using a travel-time curve, which is a graph of Pand S-wave arrival times (see Figure 13.11). You can also download it, export it or print it out. Several thousand seismographs exist at locations around the planet, continuously measuring abnormalities in the Earth's movement. approximate period of the surface waves in seconds? Geologists use seismic waves to locate an earthquake's epicenter. Practicing this technique, the students work several problems on a map of the US.
