Guess they never read about the great New Madrid quakes of 1811-12.

“THE SUBSURFACE ANATOMY OF THE BOOTHEEL’S SAND BLOWS:
REMNANTS OF THE NEW MADRID EARTHQUAKES

Earthquakes have repeatedly shattered the alluvial landforms about the Missouri Bootheel—most
recently the 1811-1812 New Madrid earthquakes. During the four greatest of earthquakes, long
fissures opened across the surface and volcanic-like sand blows erupted, venting subterranean
sands onto the surface.”

Interesting article, but it specifically says that,

During the four great earthquakes of 1811-1812, sand geysers erupted; vomiting into the sky great volumes of subterranean sands mixed with sulfurous steam and prehistoric charcoal.

In the case of the video, the article specifically states that there were no reported earthquakes when this happened. So if there was no seismic activity, how could it be blamed for the sand geyser?
