Problem:
How can we use seismic waves to determine the epicenter of an earthquake?
Hypothesis: By using the arrival time of P-waves and S-waves from seismic stations, I can determine the epicenter of an earthquake.
Data and Observations:
After you have recorded the data for the seismographs you selected to review (Step 3 in the lab), take a screenshot of your completed data table (or print it and send it directly to your instructor). You should also take a screenshot of your attempt to locate the epicenter of your selected earthquake (Step 4 in the lab). Include this screenshot in the Data and Observations section of your lab report.
Conclusion:
If you are unsuccessful at locating the epicenter, describe how you modified your work to come to the correct answers. Record the information in your lab report.
I was overall pretty much successful but I couldn’t get station three right pm 193, but it still got the epicenter even though it was a point off.
Reflection Questions:
Answer the questions located at the end of the virtual lab activity. Be sure to record your answers in your lab report.
Why are earthquakes monitored worldwide instead of in earthquake-prone areas only?
Earthquakes are monitored worldwide instead of only in earthquake-prone areas because an earthquake can happen anywhere even if the chance is really low.
How many seismographs are needed to find the epicenter of an earthquake? Why is this number significant?
Three seismographs are needed to find the epicenter of an earthquake because they use triangulation.
What is the relationship between P- and S-waves?
The relationship between the P- and S- waves is that P-waves are primary, they travel through the solid and liquid parts of earth, and they travel up and down. S-waves are secondary and only travel through solids and they cause the ground to move back and forth.
How did the study of earthquake waves lead to a greater understanding of the interior
