How would you cause an explosion in a underground facility? A small amount of explosives smuggled in each day..to build a critical mass? Or maybe a shot of natural gas into a vent system? Or a flammable liquid introduced into the water supply? Or..just a run away of some electrical equipment?
However it was done..if it was done..great.
None of those locations are near Fordo. It is located at 34.866, 50.997. NNE of Quom in the ridge below the dry lake bed. In 1973, I witnessed the Blue Angles doing a show near the Airbase just to the west of there.
