I wonder what geologic faults are in the Gulf? [I put "geologic in that sentence because I'm going to lose my mind if I see one more "Bush's fault" post. Ceased to be funny eons ago.]
The Gulf is all faults from that Chixclub meteor impact. This location is somewhat unusual for large earthquakes.
The Gulf is heavily faulted. They aren't the result of techtonic plates grinding against each other like along the Pacific coast. They are the result of subsidence.
Imagine you had piece of uncooked spaghetti a hundred feet long and you started shoving one end of a ledge. At some point before you can shove it all off, it's going to break from its own weight. That's kind of what is happening in the Gulf.
it is a well known fact that the "Bush's fault" line runs deeper and longer than the "San Andreas fault" line and causes much more damage economically, politically, and globally than most all other things combined. Most people just don't equate it with a geologic source!\sarc
