This phenomena has swept the world this year, leading to various doom and gloom speculations. As a friend of mine said once however, they predict doom and gloom only for themselves!
Dr. Khalilov is geophysicist who works in the area of geodynamics and geotectonics. Basically he studies the way the plates of the Earth move on a global scale and the key dynamics of earthquakes and geological forces.
In a recent interview for GeoChange Journal Dr. Khalilov was asked some questions about the strange sounds people have been reporting for the past few months.
Here is a snippet from that interview.
What is the nature of the unusual very low-pitched sounds reported by a great number of people in different parts of the planet since the summer of 2011? Many call them “The Sound of the Apocalypse”. Information about that comes from all over the world: US, UK, Costa Rica, Russia, Czech Republic, Australia, etc.”
DR. KHALILOV – “We have analyzed records of these sounds and found that most of their spectrum lies within the infrasound range, i.e. is not audible to humans. What people hear is only a small fraction of the actual power of these sounds.
They are low-frequency acoustic emissions in the range between 20 and 100 Hz modulated by ultra-low infrasonic waves from 0.1 to 15 Hz.
In geophysics, they are called acoustic-gravity waves; they are formed in the upper atmosphere, at the atmosphere-ionosphere boundary in particular.
There can be quite a lot of causes why those waves are generated: earthquakes, volcanic eruptions, hurricanes, storms, tsunamis, etc.
However, the scale of the observed humming sound in terms of both the area covered and its power far exceeds those that can be generated by the above-mentioned phenomena.”
