Comments on: Google Earth: Suspected Earth Impact Sites (KML) http://www.thinklemon.com/weblog/2006/01/31/google-earth-suspected-earth-impact-sites-kml/ I think there used to be a tagline about (tag)soup here... anyway...

The craters I am seeing are very large and combine features such as the arctic ocean floor topography combined with the shoreline of North America, Northern Siberia, and Europa giving a crater that appears to define the top of the planet, similar to the recently acclaimed Mars very large impact crater. Another is defined using Providence Island to the North tip of Madagascar as the center with the Coast of Africa on the west and the islands of Port Louis and Saint Denis to the South East rim. More would be the Gulf of Mexico formed by an angled impact coming in low over North America, The Caribbean sea area off the coast of Costa Rica. The Caribbean Sea area defined by Cuba on one side and the Yucatan on the other, Caymans forming the center. Hudson's Bay in Canada with at least 3 craters combined. The Bearing Sea with the Aleutians forming the Southern rim. The Yellow Sea formed by at least 5 craters. The Bismarck Sea with New Britain and Manus Island forming most of the rim. The area directly South of Port Moresby has what appears to be 2 combined craters. Many others I am sure but those are obvious.

I'd like to report it's coordinates to any interested party for possible investigation/verification. Please forward any contact information. Thanks. PRB Sir,

Only a year or so. That may seem a lot, but in geological terms... ;-) Anyway, converting from SEIS to KML takes a bit of an effort. Thanks for the reminder though. I'll look into it when I have/make some spare time. Hello Gregory,

Coming from a completely biased point a view, I would very much like to see the Cuvette Central (Africa) proposed impact added to this work. It's in the SEIS database but does not appear on your version. This feature may prove be one of the most significant tectonic features on Earth. Please see www.impacttectonics.org/gondwana.html for more details. Thank you. Sincerely Gregory Herman Caspar,

Therefore it isn't in the SEIS-database. Fortunately you can find the crater if you download the North American collection found on the <a href="http://www.thinklemon.com/pages/ge/" rel="nofollow">Google Earth Impacts page</a>. Don't forget to download the other impacts though. :-) Wetumpka Alabama is one of the 172 confirmed impact craters. Therefore it isn’t in the SEIS-database.

When I did the 'confirmed' collection I also found that some impact craters where not spot-on. The general rule being, the smaller the crater, the more off place it is due to insufficient 'resolution' in the data. But GE is a tremendous help in checking 'the facts'. As you have found yourself. (Assuming that the coordinates in GE are correct.) As for the 'mid-ocean' foul-ups, please see the southern part of the Indian Ocean with this set. You'll find a few craters that should be in South-America (Argentina specifically). I meant those, not the ones like the Silverpit in the North-Sea. On the collaboration part, I'm interested. But please note that converting the way I did with this database is cumbersome. First I took your Excel-sheet, manually fixed/altered/added the data, converted it with a script to a CSV file, imported it to MySQL (several retries), adapted the 'confirmed' KML-script, output to browser, save as XML, import to Google Earth, constructed a single KML from several continents. Hardly an efficient way to handle things. ;-) So I do have some thoughts how to go about this. To be continued... Hello David,

I am very happy to see people picking it up. Your implementation for Google Earth is excellent. Not only for general look up of the structures but also for helping to improve the accuracy/precission of the coordinates. The structures in oceans you mentioned are not a mistake! They indeed occur there. There is, however, a lot of other inaccurate, missing and non verified information in the database. I am gradually working through it and the database is being updated periodically. If anyone notices someting suspicious please, please let me know. Sir, would you please contact me at drajmon@yahoo.com? I would like to discuss a possible collaboration on future updates. Sincerely, David Rajmon Dear Sir,
