ha ha My prediction is that this area has awakened and when you see it reported on the news you'll know it's just a precursor for what that area is capable of no time line or magnitude just that it will become more active going forward.

EQ @ NewOrleans area -> see: Craton
A craton is an old and stable part of the continental lithosphere. Having often survived cycles of merging and rifting of continents, cratons are generally found in the interiors of tectonic plates. They are characteristically composed of ancient crystalline basement rock, which may be covered by younger sedimentary rock.
see the coastal plane area, there is not any 'base-rock' within 50 miles of NO,,,, it's all sediment so EQ's would have a really special source, you might be thinking an EQ up around the famous Madrid Fault EQ zone being felt in NO & Gulf-of-Mexico
further info on the ancient core lithosphere....
there is NO reason for 10km EQs in the region...other than the periodic collapses of the deep Salt Caverns in that general area......and the resulting sinkholes showing up in the landscape
