Follow the steps to complete the Locating An Earthquake Epicenter Activity
- Click the ‘Get Form’ button to access the form and bring it up in your preferred online editor.
- Begin by reviewing the objectives of the activity. Familiarize yourself with the concepts of P, S, and surface waves and how they relate to seismograms.
- In the first part of the form, analyze the sample seismogram provided as Figure 1. Identify the arrival times of the first P-wave and S-wave.
- Using Figure 2, calculate the difference in arrival times for the three specified distances (700 miles, 450 miles, and 2500 miles). Input these values in the designated fields.
- Refer to the travel-time graph to determine the distance from the epicenter for the recorded times in Figure 1. Fill in this distance in the appropriate field.
- Examine the seismograms from Figure 3, calculating distances for each station and inputting these in the epicenter data table, Table 1.
- Use a drawing compass to outline circles on the map around each station, ensuring the radii correspond to their distances from the epicenter.
- Respond to the final queries regarding overlaps of circles and corresponding locations of the earthquake. Carefully consider your responses and place them in the provided fields.
- Once all sections are completed, review your inputs for accuracy. You can then save changes, download, print, or share your completed form.
Complete the Locating An Earthquake Epicenter Activity online today and enhance your understanding of seismic wave analysis.
Seismologists locate epicenters by analyzing seismic waves captured by various monitoring stations. They calculate the difference in arrival times of the waves to determine distances from each station, then use triangulation to pinpoint the epicenter. Participating in the Locating An Earthquake Epicenter Activity gives you a hands-on approach that demystifies the scientific techniques seismologists use daily.
