There have to be three stations detecting waves, draw a circle for each station where the radius equals the distance to the epicenter. Where the three circles connect is the location of the earthquake center.
Uses the difference between arrival times of p-waves at a station to determine the distance between the station and the earthquakes epicenter.
A series of processes on the surface and inside Earth that slowly changes rocks from one kind to another
