Problem #2: Finding the Earthquake distance from the recording station Find the distance from the earthquake to the recording station 70 60 S-P Time (Seconds) 50 Example: S-P Interval = 38 seconds Distance = 380 kilometers 40 30 300 700 400 500 600 Distance (kilometers) Determine the distance from each seismic recording station to the earthquake's epicenter by using the know travel times of the S and P waves. Using Figure 5, determine the distance from the earthquake to each recording station. 70 60 S-P Time (Seconds) 50 40 30 300 700 400 500 600 Distance (kilometers) Figure 5: S-P Travel Time Curve Answers: Eureka CA distance (km): Elko, NV distance (km): Las Vegas, NV distance (km)
