On 25 January 2024, it was proposed that this article be moved from List of impact craters on Earth to List of impact structures on Earth. The result of the discussion was moved. |
I'll be adding to this page, there are still a bunch of craters with wikipedia articles already so I'll go for them first, then add in the other craters that still need work. Hope people find this page useful! -- Fxer 18:03, July 14, 2005 (UTC)
The list of earth impacts on the Impact craters page wasn't very impressive, it'd be nice to have a page with more stats on the craters at a glance, plus the coordinates link gets you right to the google satellite map of the area etc... -- Fxer 18:03, July 14, 2005 (UTC)
The impact crater of Söderfjärden is missing. El Ucca ( talk) 17:51, 2 January 2009 (UTC)
I believe that there may be two, huge, impact craters not recognized. One is the very circular structure on the northwest of Hudson's Bay, Canada, approximately 700 km across. The second is the smaller very nearly perfectly circular structure, on the southeast portion of Hudson's Bay, approximately 500 km across. Beelcher Islands are volcanic, and may have resulted from the impact penetrating the crust sufficiently to enable lava to reach the surface. Another possible large crater is Ungava Bay, 200km across, in northern Quebec, Canada. (Roger Bryenton, Sep 8, 2011)
I was thinking we should increase info on craters into a wiki for them what do you guys think-- Jk305 05:48, 27 November 2006 (UTC)
Shouldnt the UK's silverpit crater be included in these lists? Jamie| C 21:38, 10 December 2006 (UTC)
Hello anonymous user... what source do you offer for the recently added Hungen crater? I can find nothing indicating that this meteorite fall produced a known crater. There is no wiki article about it as there are for other craters. No listing in the Earth Impact Database. Neither Google Earth or a Google search on "Hungen crater" produce any discussion of this impact, to say that a crater was produced. And the coordinates do not even match what is listed in the meteorite fall databases. -- GregU 07:08, 19 January 2007 (UTC)
I came to this via the Kabaa page, where it said that part of the Kabaa at Mecca, the Black Stone, is thought to be a meteorite, possibly from Wabar in Saudi Arabia. A look at the Wabar page doesn't mention this crater, and it's not on your list. I don't feel competent to add it - any takers? Here's a relevant website: http://volcanoes.usgs.gov/jwynn/3wabar.html Jasper33 16:11, 20 January 2007 (UTC)
These excellent lists contain mainly confirmed impact sites as listed on the Earth Impact Database, widely recognized as an authoritative (and to some degree conservative) listing. So far so good, but they also contain a few unconfirmed sites, some little more than wild speculation inflated by media hype, and the general reader won't know the difference. I'd suggest we move the following to a separate table at the end entitled Unconfirmed proposed impact sites
Could also add Bedout and Sirente crater, simply because they already have their own wiki pages, but both are controversial. There are many other unconfirmed impact craters, some with way better evidence than most listed above (they just haven't had the media hype), but I wouldn't propose adding any more, just sticking to the ones that already have wiki pages.
Silverpit is a tricky one. Most impact specialists seem to believe that it will turn out to be a genuine (and excellently preserved) impact crater, but there is a long tradition of not confirming impact craters on geophysical (in this case seismic) or other remotely sensed data alone. Impact is confirmed on solid mineralogical and/or geochemical data only, which in the case of Silverpit would require drilling beneath the sea floor.
If no loud complaints or better ideas I'll do the appropriate moving shortly – Zamphuor 02:57, 28 January 2007 (UTC)
OK, I've done it. If any of these sites reach confirmed status, we can move them back into the main tables. -- Zamphuor 13:07, 29 January 2007 (UTC)
Woodleigh is constantly being misquoted as being 40km in size when the facts are proven that it is an extinction event crater of an estimated diameter of 120 km, the multi-ring Woodleigh impact structure is arguably the largest proven impact structure in Australia and the fourth largest on Earth.

Should this list still be flagged as "incomplete"? I think it contains most everything in the Earth Impact Database now doesn't it? Even though we are still finding the occasional glaring mistakes -- slow work to verify all the entries. -- GregU 21:04, 17 February 2007 (UTC)
I've been thinking of the "list by size" as a summary of the comprehensive listings below. Only those confirmed craters over a certain size, or which are otherwise notable. In some cases the numbers in this list are simplified from the numbers below. I'm not sure it's worth it to try to maintain every entry in both sections -- it almost doubles the maintenance burden since most craters don't make the top list. If we do add everything to the top list then my guess is we'll then want to split it out onto a separate page. Another option would be to try to do it all in one list that you can sort by size or by an additional continent column. But then you lose the ability to have section headings and a ToC which I like... -- GregU 05:00, 18 February 2007 (UTC)
I've just sub-divided this article, partly to overcome a coordinate template bug, but also because it's very long anyway. I've also changed the coordinate templates to the new {{ coord}}, which lets users choose the preferred display style (DMS or decimal) and has the added advantage of marking up each location with a Geo microformat. Andy Mabbett 14:04, 6 April 2007 (UTC)
I've now applied the hCard microformat to this page (but not, yet, the sub-pages - I may need to tweak it). hCard effectively wraps the Geo microformat and adds a name field. It can also include the location, but I don't think that's going to be possible inside the wiki-table markup. See Project Microformats for more about microformats.

I wonder why Shiva crater is not mentioned in the list. Is there some reason or oversight?
Raama ( talk) 10:49, 24 September 2009 (UTC)
I tightened up the inclusion criteria for this top-level list. Rather than leave it up to everyone's varying perceptions of what is notable, I made the list everything 20km or larger listed on the Earth Impact Database. That roughly equates to the current top 50, but will grow over time as more >20km craters are discovered and confirmed. I filled in a lot of craters that were missing from this list above 20km. I removed everything below 20km. Sorry - Woodleigh is back to 40km because that's what it's listed EID. Publish a paper if you want them to change it. Wikipedia uses EID's numbers.

I fixed the sorting of one of the tables, but it was painful. If someone adds a new entry, they should add a sort template, where the first paramter is the value divided by 10,000; make sure to use a decimale point and exactly five positions, then use whatever for the second parameter.

User:Titus III recently added numbers after each wiki link as follows:
See:
I removed the numbers (temporarily) because of some counting errors and also because I think the significance of the numbers is not clear enough (yet). Presumably the numbers are the number of confirmed impact craters in each continent? First the errors: there are no confirmed impact craters in Antarctica, so the number should be 0. The number for Asia should be 19 not blank. The number for North America should be 61 not 64. I suggest that the numbers need clarification, even if it is perhaps only adding the word "craters" after each number, or (my preferred version) "xx confirmed craters and yy unconfirmed craters". Another possibility could be a very brief explanation at the start of the section before "See". GeoWriter ( talk) 11:01, 5 April 2016 (UTC)

I just noticed something: the figures displayed in the Earth Impact Database map and the tables in the article itself don't match. This is the case for multiple craters, and the error ranges from being spot on (Ries crater) to being almost a factor of two out (Vredefort). I am putting a self-contradictory template at the top of the article to draw attention to this. How did this happen?-- EnronEvolved My Talk Page 15:17, 6 January 2018 (UTC)
This "impact structure" (Rocca et al., Geophysical evidence for a large impact structure on the Falkland (Malvinas) Plateau) is highly dubious and should not be contained in the table of unconfirmed craters (see https://doi.org/10.1111/ter.12284 and https://doi.org/10.1111/ter.12285), unless these latter two critical papers are also cited. — Preceding unsigned comment added by 193.170.196.53 ( talk) 14:20, 14 September 2018 (UTC)

I am putting a self-contradictory template at the top of the article to draw attention to this. How did this happen?-- EnronEvolved My Talk Page 15:17, 6 January 2018 (UTC)
This "impact structure" (Rocca et al., Geophysical evidence for a large impact structure on the Falkland (Malvinas) Plateau) is highly dubious and should not be contained in the table of unconfirmed craters (see https://doi.org/10.1111/ter.12284 and https://doi.org/10.1111/ter.12285), unless these latter two critical papers are also cited. — Preceding unsigned comment added by 193.170.196.53 ( talk) 14:20, 14 September 2018 (UTC)
More info here and at Hiawatha Glacier. Looks cool and should be added somewhere. -- Green C 22:30, 14 November 2018 (UTC)
Add Hiawatha Crater [1] of Hiawatha Glacier, per current research? It appears to be in the Top 25 in size. [2] X1\ ( talk) 01:17, 15 November 2018 (UTC)
It is in List of unconfirmed impact craters on Earth until confirmed in the Earth Impact Database. X1\ ( talk) 23:13, 19 November 2018 (UTC)

-I have noticed that Kamil crater - which has its own wikipedia page - is missing in this list.

List of impact craters on Earth → List of impact structures on Earth – A substantial number of the pages listed here are the deeply eroded remains of craters and "impact structure" is a more accurate description for all of these features. Mikenorton ( talk) 11:18, 25 January 2024 (UTC)
List can include recent confirmation of third impact crater (10 km dia) of India in Ramgarh, Rajasthan.

The instructions say to hover over the crater to obtain information about it. The Antarctic crater does not do this. It is also one which the line around it is continuous. Jokem ( talk) 05:03, 24 April 2024 (UTC)
