Good job Ekios :thup:. In addition to 3 allready placed on the map here are two other sinkholes from Turkey reported in 2012, i could find.

_http://www.cnnturk.com/2012/turkiye/03/06/aksarayda.dev.obruk/651942.0/index.html (From Aksaray, depth : 4m, diameter : 40 m, reported on March 5th)

_http://www.emlaktasondakika.com/haber/Kentbolge_haberleri/Konya_Karapinarda_4_metre_derinlikte_obruk_olustu/29101.aspx (from Konya, depth : 4m, diameter : 12 m, reported on July 20th

Both locations are from Central Anatolia , you can easily find them if you zoom in the map. Especially in Konya area there have been some other sinkhole formations in the last few years, there was one with 33m depth.

Here is a video about the one you allready put on the map, Erzincan , 30m deep, scary.

Have to say, i'm on it for just what ? Two days ... and it scares me like hell ... those 30 meters holes ... sweet mother !!! I've just watch a video of the guy getting swallowed inside one of them, wow ! :scared:

Very nice Ekios!

Thanks to you and other contributing.

Very informative.

It's quite alarming to see what's going on in the USA. If I compare with NASA's earthquake map, I can see that the sinkholes aren't located in the same areas so there's deffinately something weird 'going on'. The earth really seems to be 'opening up'. Guess the companion star is close now.

Does anybody know how many sinkholes 'form' in average every year in the USA? Are we already getting over it? Or is it more about the (perhaps unusual) locations?

Peace.

I really must say that Muxel already had a very huge job done before, her data file was an impressive complement for the US sinkholes !

(Ekios, I moved the marker from New Zealand to South Africa.)

MK Scarlett,

I have added these ones from your list:
J'ai ajouté celles-ci de votre liste:

The majority of the reports you provided are cases of land subsidence and fissures. Should they be added too?
La majorité des bulletins que vous avez fournies sont les cas de l'affaissement du sol et les fissures. Les cas devraient-ils être ajoutés aussi?

Wow really cool map, nice job. Is it just me or does it seem like most of them are appearing on/under roads?

Good question, we can use another icon maybe. Like this one

.

I'm wondering.


Quickly added those three :

Ekios and Muxel, maybe this last solution would be the best to use these locations of land subsidence and fissures as being potentially sinkholes, at least until know more about there specificities... But at this point, the most important I think (and maybe I'm wrong) is to report "any kind of sinkholes". Also, some medias could named land subsidence and fissures to occult voluntarily on not the fact of the multiplication of the sinkholes across the world these last years. FWIW.

Maybe I was wrong by including them in the list, but finally what is a sinkhole?

[quote author=Wikipedia]A sinkhole, also known as a sink, snake hole, swallow hole, swallet, doline, or cenote, is a natural depression or hole in the Earth's surface caused by karst processes — the chemical dissolution of carbonate rocks[1] or suffosion processes[2] for example in sandstone. Sinkholes may vary in size from 1 to 600 metres (3.3 to 2,000 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may be formed gradually or suddenly, and are found worldwide. The different terms for sinkholes are often used interchangeably.[3][/quote]

How could we be able to make the distinction between some and others?

Get back to Wikipdia:
Sinkholes may capture surface drainage from running or standing water, but may also form in high and dry places in a certain location.
The mechanisms of formation involve natural processes of erosion[4] or gradual removal of slightly soluble bedrock (such as limestone) by percolating water, the collapse of a cave roof, or a lowering of the water table. Sinkholes often form through the process of suffosion. Thus, for example, groundwater may dissolve the carbonate cement holding the sandstone particles together and then carry away the lax particles, gradually forming a void.
Occasionally a sinkhole may exhibit a visible opening into a cave below. In the case of exceptionally large sinkholes, such as Minyé sinkhole in Papua New Guinea or Cedar Sink at Mammoth Cave National Park, USA, a stream or river may be visible across its bottom flowing from one side to the other.
Sinkholes are common where the rock below the land surface is limestone or other carbonate rock, salt beds, or rocks that can naturally be dissolved by circulating ground water. As the rock dissolves, spaces and caverns develop underground. These sinkholes can be dramatic because the surface land usually stays intact until there is not enough support. Then, a sudden collapse of the land surface can occur.
Sinkholes also form from human activity, such as the rare but still occasional collapse of abandoned mines in places like West Virginia, USA. More commonly, sinkholes occur in urban areas due to water main breaks or sewer collapses when old pipes give way. They can also occur from the overpumping and extraction of groundwater and subsurface fluids. They can also form when natural water-drainage patterns are changed and new water-diversion systems are developed. Some sinkholes form when the land surface is changed, such as when industrial and runoff-storage ponds are created; the substantial weight of the new material can trigger an underground collapse of supporting material, thus, causing a sinkhole.

It looks have several reasons for it happens, so I do not know really. I am not geologist, maybe we could find some help because how make the distinction between a land subsidence or fissures and sinkhole?

They also write:
What has been called a "sinkhole" by the popular press formed suddenly in Guatemala in May 2010. Torrential rains from Tropical Storm Agatha and a bad drainage system were blamed for creating the 2010 "sinkhole" that swallowed a three story building and a house.[14] This large vertical hole measured approximately 66 feet (20 m) wide and 100 feet (30 m) deep. A similar hole had formed nearby in February 2007.[15][16]
This large vertical hole, called a "sinkhole" in the popular press, is not a true sinkhole as it did not form via the dissolution either of limestone, dolomite, marble, or any other carbonate rock.[17][18] Guatemala City is not underlain by any carbonate rock; instead, thick deposits of volcanic ash, unwelded ash flow tuffs, and other pyroclastic debris underlie all of Guatemala City. Thus, it is impossible for the dissolution of carbonate rock to have formed the large vertical holes that swallowed up parts of Guatemala City in 2007 and 2010.[17]
The large holes that swallowed up parts of Guatemala City in 2007 and 2010 are a spectacular example of "piping pseudokarst", created by the collapse of large cavities that had developed in the weak, crumbly Quaternary volcanic deposits underlying the city. Although weak and crumbly, these volcanic deposits have enough cohesion to allow them to stand in vertical faces and develop large subterranean voids within them. A process called "soil piping" first created large underground voids as water from leaking water mains flowed through these volcanic deposits and washed fine volcanic materials out of them, then progressively eroded and removed coarser materials. Eventually, these underground voids became large enough that their roofs collapsed to create large holes.[17]

Wow, that's a lot of holes.

Great work, so far, you guys.
