Earthquake Triangulation Concepts

This video tutorial demonstrates how to use an earthquake triangulation app to plot the location of an epicenter. The process involves determining distances from seismograms, adding and labeling seismic stations, and plotting circles for cities like Tampa, Chicago, and Dallas. The tutorial also covers finalizing the epicenter location, addressing human error, and saving the plot as a PDF for submission.

What is the first step in using the earthquake triangulation app?

• Determine the distance to the epicenter from each location

• Add the first seismic station

• Label the epicenter

• Save the plot as a PDF

Which city is used as the first seismic station in the demonstration?

• Wink

• Tampa

• Dallas

• Chicago

What hypothetical distance is assigned to Tampa from the epicenter?

• 1,000 km

• 3,000 km

• 500 km

• 2,000 km

Which city is used as the second seismic station in the demonstration?

• Wink

• Dallas

• Chicago

• Tampa

What is the distance from Chicago to the epicenter in the demonstration?

• 500 km

• 1,000 km

• 2,000 km

• 3,000 km

Which city is used as the third seismic station in the demonstration?

• Wink

• Chicago

• Dallas

• Tampa

What is the distance from Dallas to the epicenter in the demonstration?

• 500 km

• 1,000 km

• 3,000 km

• 2,000 km

What is a common reason for the circles not intersecting perfectly in triangulation?

• Faulty seismograms

• Human error

• Inaccurate distances

• Incorrect app usage

What is the final step after plotting all stations and the epicenter?

• Add another station

• Recalculate distances

• Submit the document

• Save the plot as a PDF

Why might adjustments be needed before saving the plot as a PDF?

• To correct distances

• To center the plot

• To change the epicenter

• To add more stations
