But New Madrid has experienced some big quakes in its history. Researchers have geologic evidence of several major earthquakes of around magnitude 7 and 8 striking the area over the past 4,500 years. More recently, the region experienced a series of strong quakes in 1811 and 1812. The first occurred in Arkansas on December 16, 1811, and scientistsâ best estimate for its strength is that it was a magnitude-7.7 earthquake. Six hours later, the region shook again with a similar-sized aftershock.

Share on Facebook. An unsecured debt is an obligation or debt that does not have specific property (like your house or car) serving as collateral for payment of the debt. If you fail to make payment on an unsecured debt, the creditor cannot take any of your property without first suing you and getting a court judgment. (There are a few exceptions to this rule.) A secured debt, on the other hand, has a piece of property serving as collateral for the debt. If you fail to make payments, the creditor can take the property. Common types of unsecured debts include: most department store and other credit card charges.
