Natural Event – Infrasound
Researcher Donnie Eichar, a filmmaker who traveled to the Dyatlov Pass in 2013, subscribes
to the infrasound theory. Infrasound, in this case, was from a natural flow of wind moving down the slope toward the hikers. It produced vortex, creating small tornadoes. While these tornados were far enough away from the Dyatlov tent to avoid damage, the sound (both audible and inaudible) impacted the hikers. Infrasound produces vibrations that humans cannot hear, but react to physically. It also causes nausea, confusion, delirium, and may have reached a point where the hikers could not stand being confined to a tent. Working with a NOAA, the U.S. National Oceanic and Atmospheric Administration, Eichar suggests infrasound drove the hikers from their tent, and once out, they couldn’t find their way back in. It was too dark, too stormy, and the cold was already affecting them.
