Scientist use triangulation method to locate the epicentre of an earthquake from the data collected from Seismograph.
<u>Explanation:
</u>
The seismic data from three different location is collected to locate the intersect point as the epicentre point to be determined. Each earthquake is recorded in seismogram in different location.
A seismogram is the output from a graph called seismograph, which is used to determine the epicentre of an earthquake. There are two waves namely <em>P-waves or Primary waves and</em> <em>S-waves or secondary waves </em>that are considered while finding the epicentre of an earthquake.
With the seismogram, P-waves appears first before S-waves, since they travel faster through three states of matter. Thus, data from seismograph is used for locating “epicentre of an earthquake”.
