Student’s name:TA’s name:Section:EPPS 8 - EarthquakesLab 4: Earthquake Location and Seismic WavesDue Week 6The objective of this exercise is to determine the location of an earthquake epicenter using seismogramsrecorded at three different stations. Recall that P- and S-type seismic waves travel at different speeds, sothat the farther the station is from the earthquake, the more the P- and S-wave arrivals are separated intime.Part I. Warm Up Exercises1.In the figure below, an earthquake occurs at the X at t = 0s.Station A is 120 km from the earthquake.Station B is 240 km from the earthquake.Assume the P wave velocity is 7 km/s, and the S velocity is 4 km/s(a)(2 pts) When does the P and S waves reach Station A?
