NOTE FOR VISITORS

Here you can read about: the 1908 Tunguska event; electrophonic sounds, geophysical meteors, and many other exciting things. The site is under permanent updating.

A few words about me, i.e. the author, Andrei Yu. Ol'khovatov.
By the way, please pay attention that sometimes my surname is translated in English as Olkhovatov, i.e. without apostrophe (compare with: Ol'khovatov). It is because the apostrophe means "myagkii znak" in Russian (a Russian letter meaning a sign of softening of spelling), and the letter is absent in English. By the way in German you could find me as: Andrei Olchowatow .
I was born in 1960 in Moscow, Russia. In 1983 I graduated from the Physical Department of the Moscow State University.
In 1992 I have defended my thesis/dissertation, and became Cand. Sc. (Phys.&Math.), which corresponds to Ph.D. in USA approximately.
From 1983 to 1986 I was working in the Radio Instrument Industry Research Institute. From 1987 to 1992 I was working in TsNPO "Vympel", and then have returned to the institute, where I worked as a senior scientific worker. In 2001 I got off the job at the institute and moved to a part-time job in a civil non-state firm, which has a little (if anything) to do with science. Now I am a retired worker (a pensioner).So now in science I am independent researcher/expert, and I feel much more free in expressing my scientific opinion.
Despite that noboby pays for my scientific investigations, I consider science as my work, and not just my hobby. My hobbies are: listen to good music, especially such as swing and classic rock'n'roll,
In science I am interested in manifestations of tectonic activity, atmospheric electricity phenomena, meteor phenomena, and in unexplained natural phenomena in general. Here are some of them (I suppose to add some more later):

A BRIEF VERSION OF 'THE TECTONIC INTERPRETATION OF THE 1908 TUNGUSKA EVENT'- My idea on the origin of the 1908 Tunguska event (I can say, that it becomes rather popular in Russia).

A LARGE VERSION OF 'THE TECTONIC' INTERPRETATION OF THE 1908 TUNGUSKA EVENT - Large version of the article which goes to another free web-host www.tunguska.eu5.org/tunguska.htm (with less web-host advertising). If for some reason the latter is not accessible, then you can read an older version at www.olkhov.narod.ru/tunguska.htm still.

TUNGUSKA RESEARCH AND OTHER NEWS- Here you can read news on the 1908 Tunguska event's research (which are not presented in the above-mentioned Tunguska article) and on other topics.

TUNGUSKA 2008 INTERNATIONAL CONFERENCE - Info on the the TUNGUSKA 2008 International conference.

TUNGUSKA 2003 INTERNATIONAL CONFERENCE - Info on the the TUNGUSKA 2003 International conference.

TUNGUSKA 2001 INTERNATIONAL CONFERENCE - Info on the TUNGUSKA 2001 International conference.

THE 1998 KRASNOYARSK INTERNATIONAL CONFERENCE ON TUNGUSKA- You can read about the conference and its abstracts.

TUNGUSKA AND OTHER PICTURES- Here you can see pictures related with the 1908 Tunguska event and on other topics.

CATALOG OF TUNGUSKA WITNESS'S ACCOUNTS - There are (in Russian) several hundreds Tunguska witness's accounts in a form of a Word-file.

GEOPHYSICAL METEORS - This www-page is devoted to the phenomenon, which resembles meteors, but has non-meteoroidal origin (some of them are real mini-Tunguskas!). The item below, "ROCKET LIGHTNING, MAYBE" is on other possible examples of geophysical meteors, associated with aviation.

"ROCKET LIGHTNING, MAYBE" - A poll conducted by AVIATION WEEK & SPACE TECHNOLOGY magazine revealed that 2/3 of participants were not satisfied with NTSB conclusion that TWA Flight 800 crash was caused by a spontaneous fuel tank explosion. Indeed the conclusion has problems in explaining reports of numerous eyewitnesses of 'streak of light', etc.. So many people think that it was a missile... But couldn't the streak be something else than a missile?...

METEOROIDAL METEORS - This www-page describes 'usual' i.e. astronomical meteors, produced by spacebodies (meteoroids). Despite that in general the meteor phenomena are rather well-understood, there are still many unknown and/or anomalous aspects. In there you can read my AIAA Paper 2000 - 0589 on anomalously high meteors. Another mysterious meteor phenomena - electrophonic sounds are in the separate section below, due to their importance.

ELECTROPHONIC SOUNDS - Electrophonic sounds are sounds simultaneous with a flight of a bright bolide. Modern science just recently was to recognize them, as their nature is still a mystery. In there you can read about them, including my letters published in METEORITE!, and NEW SCIENTIST magazines. Please pay attention that this link goes to my web-page on another free-web-host.

TEKTITES - Discussion of these and similar anomalous rocks.

VIDEO OF METEORS- A special web-page on some meteors which I was able to video. The videos are as html5-video, so some browsers may have problems with the videos unfortunately. Associated text is in Russian and in English.

You can e-mail me: olkhov77$gmail.com (please, change $ to @ due to anti-spam)

This my www-page was previously placed at my www-site www.geocities.com/olkhov.
But it was announced that the free geocities.com web-hosting is to be closed on October 26, 2009. So I have to move my geocities www-pages to new free web-host narod.ru . Lately the owner of web-host narod.ru have changed and some visitors began to write about problems with access due to web-host advertising. So I decided also to post some popular articles to another free-web-host with (currently) less web-host advertising www.tunguska.eu5.org.
