From: Angels Do Speak!
At 7:31pm on 7/13/2010 a Seraphim Eye view of an underground area, an Angel Being is holding the pillars in place, the ground is trimmering. Another Angel Beings thinks it may be underground nuclear testing or explosions. If the pillars fall the ground will sink in.
According to Random House Timetable of History Second Revised Edition (1991) 1975 to 1977 The US and USSR signed a disarmament treaty that limited underground nuclear explosions in 1976.
I wonder if the old agreements with countries that have reorganized are still in effect?
