Professor Elchin Khalilov's information explaining the strange sounds coming from the sky, communicated to the WOSCO information agency has aroused great interest worldwide. The debate over this interview is still going on. A lot of letters have been sent to the agency requesting a more detailed account of these studies. Professor Khalilov has kindly agreed to give an exclusive interview to the WOSCO information agency. It is to be reminded that Professor Khalilov is President of the Global Network for the Forecasting of Earthquakes (London, UK) and Chairman of the International Committee GEOCHANGE on Global Geological and Environmental Change (Munich, Germany).
Dear Professor Khalilov, some readers express doubts that the interview to the WOSCO information agency about recording strange sounds from the sky and their explanation was given by you?
I am aware of that because I have received letters with the same question. That is why I would like to confirm personally that it was I who gave the interview to the WOSCO information agency about recording strange sounds from the sky and their explanation by acoustic-gravity waves generated as a result of the powerful solar wind at the atmosphere-ionosphere boundary as well as before strong earthquakes.
Some readers ask whether it is possible to record those sounds with a standard microphone, or some special equipment is required?
The audible part of those sounds, although of very poor quality, can be recorded using a standard microphone. Those low-frequency sounds are well heard in many amateur video recordings available on the Internet.
To record acoustic-gravity waves professionally, some special geophysical equipment, namely directional antennas with complex registration system are required.
Do you still register those strange sounds?
Yes we do, especially during major solar flares and before some large earthquakes, but they are not always audible to humans.
What are the prospects for these studies?
The fact is that our ATROPATENA stations which record lithospheric stress waves by measuring three-dimensional variations of the gravitational field are also equipped with other geophysical instruments - seismic stations, highly sensitive tiltmeters, antennas recording acoustic-gravity waves emanating from the sky etc.
Acoustic-gravity waves appear before strong earthquakes as well; this fact is well known to geophysicists and new earthquake prediction methods are developed on its basis. The Global Network for Forecasting of Earthquakes, too, is planning to make greater use of acoustic-gravity waves to predict and study the process of preparation of strong earthquakes as an additional geophysical parameter. Recently, we have documented a number of interesting facts about amplification of acoustic-gravity waves before some large earthquakes. We are currently developing a model of appearance of acoustic gravity waves in the atmosphere before strong earthquakes.
How can the intensification of acoustic-gravity waves be explained?
We believe it may be connected to both the higher solar activity and activation of geodynamical processes. This is indicative of the increased risk of strong earthquakes and volcanic eruptions all over the globe in the near future.
Do you plan to cooperate with other influential scientific bodies?
Certainly. We have prepared special offers for cooperation for NASA, USGS, NOAA, Russian Geophysical Service and to some other countries. We hope that potential scientific partners will be interested in our cooperation proposals.
Thank you very much for the interesting interview.
