Michael Janitch, who describes himself as an independent scientist whose studies are sometimes "controversial," believes the Bama booms could have been caused by seismic pressure transfer along plate boundaries.



A representative from The US Geological Survey told WBRC, while it is possible seismic activity could cause the noise, it's also unlikely.



"The most likely scenario is an airplane or airplanes," said WBRC Chief Meteorologist J.P. Dice, who is also a licensed pilot.



He believes the booms are the results of the military breaking the sound barrier.



"For example if the sonic boom happened in Anniston, the airplane can continue to travel supersonically. And as long as it's exceeding the speed of sound, that boom travels with it," said Dice.



That would certainly explain why most of these booms have been heard over a large area.



WBRC also reached out to NASA representatives again to see if it they had any new theories. They said they are still not sure as to the boom's source.
