Question
Explore the interactive site below to answer the following questions. IRIS: Three Seismograph Stations 2 The interactive site demonstrates how the S - P time gap is used to triangulate the epicenter of an earthquake. A. Which station is closest to the earthquake epicenter in the diagram? [ Select ] [ Select ] Standing Stone, PA (SSPA) Tepich, Mexico (TEIG) Isla Socorro, Mexico (SOCO) B. Which station is furthest from the epicenter? I Select | C. Which station has the shortest S-P time gap recorded on the seismogram? [ Select] D. Which station has the longest S-P time gap recorded on the seismogram? [ Select] E. Why is the S-P time gap different at different stations? Similar to a runner and a walker that begin a foot race at the same point, as the distance from the starting block increases, the distance between the two racers increases because they are traveling at different velocities. This is an analogy for the S wave and the P wave. These two waves originate at the earthquake focus and travel out toward different seismograph stations. (The L and R wave also originate at the focus, but they are not relevant to this S-P time gap exercise). The S wave and P wave travel at different velocities. As the distance from the focus (or epicenter if we are looking at a map of the ground surface) increases the S-P time gap increases. Thinking about the the analogy above. Which seismic wave does the runner represent? [ Select ]
