List of impact craters on Earth
This list of impact craters on Earth contains a selection of the 188 confirmed craters (as of 2016) as given in the Earth Impact Database. To keep the lists manageable, only the largest craters within a time period are included. The complete list is divided into separate articles by geographical region.
Confirmed impact craters listed by size and age
These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to the best available estimate of the original rim diameter, and may not correspond to present surface features. Time units are either in kiloannum (ka) or megaannum (Ma).
Young craters (10 ka or less)
Less than ten thousand years old, and with a diameter of 0.1 km (100 meters) or more. The EID lists only 7-8 such craters, and the largest in the last 100,000 years is the 4.5 km Rio Cuarto crater in Argentina, though there is some uncertainty regarding its origins and age, with some sources giving it as < 10 ka while the EID gives a broader < 100 ka.
The Kaali impacts (c. 2000 BC) during the Iron Age may have influenced Estonian and Finnish mythology, the Campo del Cielo (c. 2000 BC) could be in the legends of some Native American tribes, while Henbury (c. 2200 BC) has figured in Australian aboriginal oral traditions.
(approx. in km)
|Wabar||Rub' al Khali desert||Saudi Arabia||0.1||0.2||~1800 AD|
|Campo del Cielo||Chaco||Argentina||0.1||4.0||2000 BC|
|Henbury||Northern Territory||Australia||0.2||4.2||2200 BC|
|Morasko||Stare Miasto||Poland||0.1||5.0||3000 BC|
|Boxhole||Northern Territory||Australia||0.2||5.4||3400 BC|
|Macha||Sakha Republic||Russia||0.3||7.3||5300 BC|
|Rio Cuarto||Córdoba Province||Argentina||4.5||<10||<8000 BC|
The EID gives a size of about 50 meters for Campo del Cielo, but other sources quote 100 meters.
Large craters (10 ka to 1 Ma)
From between 10 thousand years to 1 million years ago, and with a diameter of 1 km or more. For comparison, the famous Meteor Crater (or Barringer) is roughly 1 km. The largest in the last one million years is the 14-km Zhamanshin crater in Kazakhstan and has been described as being capable of producing a nuclear-like winter.
|Name||Location||Country||Diameter (km)||Age (thousand years)||Coordinates|
|Meteor Crater||Arizona||United States||1.2||49|
|Tswaing||Pretoria Saltpan||South Africa||1.1||220|
|Zhamanshin||Kazakhstan||Kazakhstan||14.0||900 ± 100|
Larger craters (1 Ma to 10 Ma)
From between 1 and 10 million years ago, and with a diameter of 5 km or more. If uncertainties regarding its age are resolved, then the largest in the last 10 million years would be the 52-km Karakul crater which is listed in EID with an age of less than 5 Ma, or the Pliocene. The large but apparently craterless Eltanin impact (2.5 Ma) into the Pacific Ocean has been suggested as contributing to the glaciations and cooling during the Pliocene.
|Name||Location||Country||Diameter (km)||Age (million years)||Coordinates|
|Elgygytgyn||Chukotka Autonomous Okrug||Russia||18||3.5|
Largest craters (10 Ma or more)
Craters with a diameter of 20 km or more are all older than 10 Ma, with the exception of Karakul which seems to have an uncertain age. There are more than forty such craters. The largest two within the last hundred million years have been linked to two extinction events: Chicxulub for the Cretaceous–Paleogene and the Popigai impact for the Eocene–Oligocene extinction event.
Large unconfirmed craters
The largest unconfirmed craters 200 km or more are significant not only for their size, but also for the possible coeval events associated with them. For example, the Wilkes Land crater has been connected to the massive Permian–Triassic extinction event.
|Name||Location||Country||Diameter (km)||Age (million years)||Coordinates|
|Australian impact structure||Northern Territory||Australia||600||545|
|Shiva crater||offshore of India||India||500||65|
|Wilkes Land crater||Wilkes Land||Antarctica||480-500||250-500|
|Ishim impact structure||Akmola Region||Kazakhstan||300||460-430|
|Bedout||offshore of Western Australia||Australia||250||250|
|East Warburton Basin||Southern Australia||Australia||200+||300-360|
All craters listed alphabetically
As of April 2015, the Earth Impact Database (EID) contains 188 confirmed craters. The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian craters are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry, with the small but well-funded European continent having a large percentage of confirmed craters. It is suggested this situation is an artifact, highlighting the importance of intensifying research in less studied areas like South America and elsewhere.
