The video tutorial explains how to calculate the location of an earthquake using seismographs. It involves three main steps: calculating the time difference between P and S waves, converting this time difference into distance using a graph, and finally using these distances to draw circles around the locations on a map to find the intersection point, which indicates the earthquake's location.
