Could the strange booms shaking parts of the U.S. be linked to secret military tunneling beneath our feet? Some believe that America’s underground is buzzing — literally — with covert construction and deep-base expansion.
A Message from a Strange Sounds Reader
The story began with a message from one of our community members who connected
mystery booms across the U.S. to large-scale underground projects:
“Ask Jesse Ventura — he exposed the ‘Oz Ark’ survival city being built beneath the Ozark Mountains. There are miles of tunnels, sealed access points, and an enormous blast-proof command post. The Ozarks were named for a network of caverns that could act as an ‘ark’ during an apocalypse.”
According to the email, these tunnels could be part of a hidden system — possibly military — stretching from Kansas through Arkansas and even as far as Texas, using nuclear-powered tunnel boring machines (TBMs) capable of melting rock and creating smooth, glass-lined tunnels up to five miles per day.
Public Clues and Official Projects
A report from Wired once claimed that the U.S. Air Force was developing an underground transit system to move and launch nuclear missiles. Such a network would require deep, shockproof tunnels capable of surviving enemy strikes — and would naturally produce seismic noise during excavation.
Each tunnel would supposedly connect to hidden “launch portals,” forming an underground doomsday subway stretching across the country. Multiple defense contractors were allegedly studying similar technologies, including the legendary “Subterrene” — a Los Alamos-designed machine that melts rock using nuclear power.
Are Deep Underground Military Bases (DUMBs) Connected?
Researchers and whistleblowers have long alleged the existence of more than 100 Deep Underground Military Bases (DUMBs) across the United States — interconnected by high-speed maglev trains and buried several miles deep.
These bases are said to exist beneath major cities, air force bases, and even beneath
Denver International Airport — famous for its apocalyptic murals and conspiracy lore.
Others, like the Dulce Base in New Mexico, have become legendary for rumored genetic experiments and psychological research.
Could today’s unexplained mystery booms and tremors be the acoustic signatures of massive tunnel boring operations?
The Subterrene: Melting Rock with Nuclear Power
Patented by Los Alamos scientists in the 1970s, the Subterrene tunneling machine
was designed to liquefy rock into a glassy lining as it advanced. This would allow for near-silent tunneling — but smaller quakes or subsonic “booms” could still reach the surface as pressure waves.
Could These Projects Explain the Booms?
The correlation between localized tremors and repeated boom reports across the U.S. has raised eyebrows for years. If underground construction is ongoing — especially at depth — it could generate micro-quakes, low-frequency sound waves, and even surface vibration similar to explosions.
Some Strange Sounds readers suggest these could also be linked to high-speed subterranean transit experiments or classified military logistics networks — connecting
facilities from Colorado to New Mexico, Texas, and beyond.
Other readers point out that similar architectural hums have been explained by wind resonance — but the depth and vibration patterns of these booms remain different,
more akin to underground detonations or drilling reverberations.
So What’s Really Happening Beneath Us?
We can’t say for sure. But it’s undeniable that massive underground engineering
is technologically possible — and strategically desirable. Whether the mystery booms are linked to DUMBs, missile tunnels, or something else entirely, one thing is clear: the Earth beneath America may be far busier than it appears.

The nuclear machines that supposedly would melt a tunnel would not work due to what should be obvious reasons, but there are some pretty fast TBMs in existence, and a patent on a system that would use heat to fracture rock, then remove it mechanically, and then vitrify the sides of the tunnel. Also, while there are many secret underground bases, few if any would be two miles underground due to the heat and pressure at that depth, and the unnecessary expense of going that deep. I’ve written an article on the subject that was published in “Atlantis Rising” magazine.
