Finding the Epicenter

Guiding Question: How can you locate an epicenter.
Hypothesis: We have to find where the earth quake was felt the most. The map shows us where all three disturbances met.

City	Difference in P and S Wave Arrival Time	Distance to Epicenter
Denver, Colorado	2min 40 sec	1,600 km
Houston, Texas	1 min 50 sec	1,000 km
Chicago, Illinois	1 min 10 sec	600 km

Analyze and conclude:

1. Tennessee

2. 

3.   First- Chicago      Last- Colorado

4. About 3,200 kilometers

5.

6. It is necessary to have 3 locations so you can find where all three locations or more intersect/come together. This is important because this way people could know where the most danger is going to be.
