    Step 1
    The two types of waves produced during earthquakes are P-waves and S-waves. The P waves are primary waves and they arrive at the detector first. The S-waves reach the detector second. The P-waves are longitudinal in nature and the vibrations are along the same direction as the direction of travel. In contrast S-waves are at right angles to the direction of travel. Both waves are detected by the seismometer.

    Step 2
    To locate the epicenter of an earthquake there is need to examine the seismograms ...
