Locate the Epicenter

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.)

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:

• One game of H-O-R-S-E with Mr. Hoegh
• A Homemade Christmas Card from Mr. Hoegh's daughters

Earthquake Sampler

Earthquakes have had quite an impact on our society in the past, and they will continue to have that Earth-shattering (literally!) impact in the future. It is highly unlikely that any of us have physically experienced one of these natural disasters, and I hope that none of us ever will. What do you think it would be like to experience a Great Quake? What would you do? How would you feel about the total loss of control in the situation? You will learn about some of the Great Quakes in history. Through first-hand accounts of people who were fortunate to live through a large earthquake, you will get a chance to learn about what it was like to experience one of these historical natural disasters. The details for today's activity are found HERE.

In your blog response, remember to answer TWO of the three choices. As always, I look forward to reading what is written!

a. What was the most memorable story, image, or fact about the earthquake you researched? Why?
b. What do you think it was like to live through the earthquake you researched?
c. Have you ever experienced another natural disaster, such as a tornado, hurricane, severe thunderstorm, or flood? Create your own personal recollection of living through the destruction that event caused.
