    Earthquakes generate sound waves inside the earth. In case of the earth, both transverse (S) and longitudinal (P) waves can propagate. Typically, the speed of S waves is about 4.5 km s^-1 and that of P waves is 8.0 km s^(-1) . A seismograph records both P and S waves from an earthquake. this difference helps us to find the distanec of the point of origin of the earthquake. this point is called the epicenter. Q. if at the location of a seismograph the P waevs arrive 2 minute earlier, the distance of the epicenter from the location of the seismograph is

The reading of the time lag between the arrival of S and P waves gives us the distance of the epicenter from the location of a seismograph. the readings of what minimum number of seismographs would be necessary to pinpoint the location of an epicenter?
