Can't speak to any seismic effects on that date or any other, but mushroom
clouds are common with large explosions of any kind.  They are produced by
the explosion's hot gases rising convectively until they cool at some
altitude and spread laterally.

Sounds like someone's attempting to monger a rumor....
