A.) A quick way to determine the distance from a location to the origin of a seismic wave less than 200 km away is to take the difference in arrival time of the P wave and the S wave in seconds and multiply by 8 kilometers per second.

B.) Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs located in different directions.Apr 15, 2016

The distance of the seismic recording station from the earthquake epicenter is determined by the time difference between the first arrival of P wave and the S wave which is known as SP interval.

Here the SP interval is : 4:30 second.

We need additional information about the distance travelled by P wave and S wave in kilometers to find out the location of the epicenter.

Epicenter :

The two waves P and S travels in every direction away from the source of an earthquake known as epicenter.
