Collisions with objects from space

Hi all,<br />First post, please be kind <img src="/images/icons/wink.gif" /><br /><br />I was wondering if there is any catalogue/web site/ whatever listing the confirmed, or suspected, impacts upon the Earth by objects from space in recorded history? By impacts, I mean air burst, or other events that left tangiable marks upon the Earth, like debris or craters. I'm not really interested in the fireballs as seen by amateur video camera men in recent years.<br /><br />The only one that I could thing of was the 1908 Tunguska event, but then I found out about a few more this century. I suppose the one thing that could cause identification of events in our recorded history difficult was the prevalent scientific view a few centuries back saying that stones could not fall from the sky! I wonder how many impacts/explosions have been attributed to thunder or lightning...?<br /><br />Best wishes<br /><br />Paul

Here's an interesting circular feature. Probably not a crater, but fun to compare to features that are.<br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

Thanks - very interesting. I found the SEIS_database7.xls Excel spreadsheet on one of the sites very interesting...I had no idea there were so many impacts in recent years!

Many thanks! You've provided more information than I initially hoped for!<br /><br />I do often wonder about the unknown airbursts, seen by meteroites....I recall reading that a satellite in the 1970s picked up a huge explosion over South Africa, which was misinterpreted as a nuclear weapon being detonated. There followed a flurry of ffrantic phone calls between the US and the South African government!<br /><br />Also, AFAIR, Omni magazine c. 1986 reported that weather satellites would often show tiny black blobs over the Earth. A study of the satellite revealed that this was not due to pixelation problems with the camera, but were real events, and some people hypothesised ice meteroites that would vapourise very quickly as they entered the atmosphere... <br /><br />With best wishes<br /><br />Paul

Maybe someone can elobarate? <br /><br />
