Arkansas Faults


The upper Mississippi Embayment is underlain by faults of the New Madrid Fault Zone, the most active earthquake zone in the central United States. The New Madrid earthquakes of the winter of 1811-1812 were the strongest in recorded United States history and were caused by movement along the New Madrid faults in Missouri and extreme western Kentucky.

A new fault has been discovered in Arkansas.  Scientists say it could cause an earthquake with a magnitude of 7.  Read the full story HERE.  

The Exploratorium has several earthquake and volcano activities for students HERE.

There are directions HERE for making a squeeze box to  model faulting and folding.  There is a website where one can be purchased HERE. squeezebox
