You are monitoring seismic activity in a seismically active region. Describe the differences between primary (P-waves) and secondary (S-waves) seismic waves, and explain how their behavior can help determine the location and magnitude of an earthquake.
a) P-waves are compression waves that move in a straight line from the earthquake source; S-waves are shear waves that move perpendicular to wave direction. By triangulating seismic data from multiple stations, scientists can pinpoint earthquake epicenter location and estimate magnitude.
