An Internet Study of Arkansas Earthquakes
Purpose: To study earthquakes in general and specifically the New Madrid and other earthquakes in Arkansas via the Internet.
Introduction:
This lab is to reinforce the information presented in the text and lecture notes about earthquakes and to acquaint the student with the New Madrid Seismic Zone, the earthquakes which have occurred there, and other earthquake phenomena in Arkansas. You will be referred to a number of specific Internet sites for specific links, but you are welcome to explore other parts of those sites. Like most topics, there is more information on the net on the New Madrid earthquakes than one can hope to examine and absorb.
Procedure:
1) Read the rest of the information on this exercise BEFORE starting the lab.
2) The questions at the bottom are approximately in the same order as the procedure and it will be easiest to answer them as you go through the steps.
3) Go to the following websites and read the sections to answer the questions.
