    1. This diagram is between difference in travel time (ts – tp) and tp (x -axis), the slope of the best fit line is dependent on S-wave and P-wave velocity.
      This best fit line when extrapolated to meet x-axis when difference in travel time becomes zero, at the source, to give the origin time of Earthquake

      Hope this helps!
