Locate the Earthquake

Problem: Where is the earthquake’s epicenter, and when did it happen?
Information: P Waves travel an average of 5000 m/s through North America. S Waves travel an average of 3000 m/s. You also have a record of earthquake activity from five different seismograph stations throughout the United States. The seismograms are visible on this map. (Open these seismograms in a new tab in order to get a good look - you will have to right-click on the seismogram to do this.)
View Locate the Earthquake in a larger map

After you figure out how far each station is away from the epicenter, use this mapping tool. It will allow you to draw measured circles around different locations to pinpoint this earthquake’s epicenter. Good luck!

In your comment below, answer these simple questions:
  1. Where did this earthquake happen? (Where was the epicenter?)
  2. When did this earthquake happen? (answer to the nearest second)
  3. How did you figure it out?
Prizes for figuring out the answers to this problem include the following:
  • 3 Bonus points on your Earthquakes Standard Check
  • Mike & Ike's with Mr. Hoegh
  • One game of H-O-R-S-E with Mr. Hoegh
  • A Homemade Christmas Card from Mr. Hoegh's daughters
  • One game of catch (football, baseball, softball, or frisbee) with Mr. Hoegh
  • 15 Minutes of Pepper (volleyball) with Mr. Hoegh
  • 2 Karaoke Songs by (or with) Mr. Hoegh

    1)New Madrid, Missouri.
    2)11:15:30
    3) By finding the SP lag time and then finding the distance, making circles on Google Maps editor, then finding the intersection of the circles, and then guessing by which one was the closest to the intersections.

    1. New Madrid
    2. 11:15:16
    3. Followed Steps, made circle of radius and we looked where the circles intersected.

    1) New Madrid, Missouri
    2) 11:15:30
    3)Found the SP lag time then used it to find the radius of various locations of where the earthquake would hit. Then, made circle on Google Maps and found where they intersected. Looked for the closest major name where they all relatively hit.

    3. Found the SP lag time for each major city and then made a circle on Google map. Found out where they all intersected and looked for the nearest town.

    Number One:The epicenter was in New Madrid, Missouri
    Number Two:The earthquake happened at ll:15:30
    Number Three:You find the SP lag time, find the radius of it around the area. You do this for all the spots and they are all by New Madrid, Missouri.
