What you put together is pretty fearful and doomy. 5 or 10 minutes. That seems like an awful long time for a earthquake to last. Usally its only seconds to a couple minutes tops.

The San Andres always thought to be a seperate Fault has now been added to the Cascadia Fault. They discovered they are joined and California has alot of sister faults also that intersect.

The New Madrid even with these too combined still gets the prise. Its huge. Encompasses almost 12 States along the East Coast and Inland all the way to the tip of the great lakes. It will split the USA in half if it ever goes.
