What is the difference between the focus and an epicenter of an earthquake? In this exercise, you will first identify the \( \mathrm{P} \) and \( \mathrm{S} \) waves on three different seismograms. I explain how geologists use \( \mathrm{P} \) and \( \mathrm{S} \) waves on seismograms to identify the location of an earthquakes epicenter in the short video. A seismogram is a record of the vibrations caused by an earthquake at a specific measuring station (or seismometer). This record shows the separate arrivals of the P-wave and the S-wave generated by the earthquake. Note that the P-wave arrives first, but the S-wave produces more shaking. The arrival times for both waves, the interval between them (i.e., the time lag), and the maximum amplitude of the S-wave are important pieces of information on the seismogram. Question 2 What is the type of body wave to arrive first at a seismic station? S-waves P-waves L-waves R-waves This is a seismogram for Buenos Aires, Argentina. What time did the P-wave arrive in Buenos Aires? Seismogram recorded at Buenos Aires, Argentina 22:57:00 22:57:18 22:59:29 \( 23: 00: 00 \) When did the first S-Wave arrive in Buenas Aires (using the seismogram from the question above? 22:57:00 22:57:18 " 22:59:29 23.00.00 Question 5 1 pts Using the information from the questions above, what is the S-P time lag in Buenos Aires? (Hint: subtract the arrive time of the P. wave from the arrival time of the S-wave). The S-P time lag is minutes and This is a seismogram for La Paz, Bolivia. What is the S-P time lag for La Paz? The S-P time lag for La Paz is minutes and seconds. This is the seismogram for Lima, Peru. What is the S-P time lag for Lima? The S-P time lag for Lima is minutes and seconds.
