Mysterious "apocalyptic" sounds in Arizona, USA. Residents say it is explosively loud sounds. Where do they go and what is the cause of their appearance is not known.
It should be noted that the sub-critical non-nuclear underground experimental explosion that produced in the United States detonated at the Nevada test site and in no way involved in the "sounds of the Apocalypse" in Arizona.
Recall that in the last days of thunder sound and shake the earth began to be registered as early as 7 states in America.
