Could be the super eruption within yllowstone....
some will giggle
but all Americans will feel it
not to mention the world
I don’t want to be near Yellowstone if it goes! Here is the link for Arkansas action: http://earthquake.usgs.gov/eqcenter/recenteqsus/Maps/US2/33.35.-94.-92.php
Oh dear, that was my first thought too.
They have been warning us for a while that Yellowstone was due. And it would certainly be felt down to Arkansas.
This would shake up the world in more ways than one.
