Earthquakes produce two kinds of seismic waves : The longitudinal primary waves (called S waves ) and the transverse secondary waves (called S waves ) . Both S waves and P waves travel through Earth’s crust and mantle , but at different speeds ; the P waves are always faster than the S waves , but their exact speeds depend on depth and location . For the purpose of this exercise , we assume the P wave’s speed to be vp = 8330 m/s while the S waves travel at a slower speed of vs = 4050 m/s .Suppose a seismic station detects a P wave and then delta t = 95.3 s later detects an S wave . How far away is the earthquake center ? Answer in units of km .
