EXERCISE 1 DATA SHEET
1. What is the latitude and longitude of your epicenter?
Latitude: ________________
Longitude: ______________
2. Based on your results, would it be more or less beneficial to use more than three
seismograph stations?
3. Select the link here to download and run the Earth’s Tectonic Plates.kmz file in Google
Earth™. Is the epicenter near a plate boundary? Circle the correct answer.
YES
NO
4. What type of plate boundary is located near the epicenter?
A. Convergent
B. Divergent
C. Transform
D. The epicenter is not near a plate boundary
5. How do P- and S-waves, respectively, move through the Earth? Draw lines in the circles to
show the movement.

6. Read the information about tsunamis and faults below, then complete the related
activities:
Tsunamis are formed as a result of sudden displacement of a large volume of water by
significant vertical motion on a fault at the bottom of a volume of water.
Label the different types faults and then hypothesize which are the most likely to generate
tsunamis.
Hypothesis:
7. Click the link here to download and run the Hazards.kmz file in Google Earth™. Select
“Tsunami Source Events”, “Tsunami Observations”, “Significant Earthquakes”, and “Significant
Volcanic Eruptions.” Do you see any relationships among earthquakes, volcanoes, and
tsunamis? Explain why or why not.
