World's Only Moving Mud Puddle

Here's my take: Definitely related to the earthquakes mentioned for it's movement.  The tectonic plates above this high pressure pocket of gas are shifting  causing what looks like the mud puddle moving but in fact is the earth crust shifting.  It may not be detectable by typical surveying methods as the earth's magnetic field is also altering as these plates shift.  There really isn't a good way to counteract this phenomenon but you can attempt to anticipate it's movement and provide an open channel to relieve pressure perhaps a few years in advance prior to the pressure's main throat reaching that area of the crust.  This pressure relief channel would have to be somewhat sizable; think along the lines of a typical sheet pile system for a bridge pier foundation for the golden gate bridge but deeper.  It's interesting to note that there doesn't seem to be much water release from this mud puddle; it's movement is more from the continuous carving of the crust due to the extremely high pressure.  Kind of reminds me of a water jet cutting machine on a grander scale where the earth's crust is the medium we are cutting through.  My only question would be if you are able to somehow relieve this pressure which is undoubtedly created by the weight of the earth above, would you create an even bigger problem? What would the impact be of this large amount of carbon dioxide release on our atmosphere? How would the earth's crust behave above a no longer pressurized void between the earth's crust and most likely the mantle?  Could Earth's atmosphere become similar to Mar's if this large level of CO2 is no longer contained within the Earth's lithosphere?
