This list of impact structures on Earth contains a selection of the 190 confirmed craters given in the Earth Impact Database as of 2017.[1][a]

To keep the lists manageable, only the largest impact structures within a time period are included. Alphabetical lists for different continents can be found under Impact structures by continent below.

Confirmed impact structures listed by size and age

These features were caused by the collision of

rim diameter, and may not correspond to present surface features. Time units are either in ka (thousands) or Ma
(millions) of years.

10 ka or less

Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi)

ka[2][4] while the EID gives a broader < 100 ka.[3]

The

For the Rio Cuarto craters, 2002 research suggests they may actually be aeolian structures.[10] The EID gives a size of about 50 m (160 ft) for Campo del Cielo, but other sources quote 100 m (330 ft).[7]

From between ten thousand years and one million years ago, and with a diameter of one km (0.62 mi) or more. The largest in the last one million years is the 14-kilometre (8.7 mi) Zhamanshin crater in Kazakhstan and has been described as being capable of producing a nuclear-like winter.[11]

1 Ma to 10 Ma

Elgygytgyn
, 18 km (11 mi)
Bosumtwi, 10 km (6.2 mi)

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-kilometre (32 mi) 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.[15]

10 Ma or more

Craters with diameter 20 km (12 mi) or more are all older than 10 Ma, except possibly Karakul, 52 km (32 mi), whose age is uncertain.

There are more than forty craters of such size. 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.[18]

Impact structures by continent

As of 2022, the Earth Impact Database (EID) contains 190 confirmed impact structures.[1] The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian structures are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry,[21] with the small but well-funded European continent having a large percentage of confirmed impact structures. It is suggested this situation is an artifact, highlighting the importance of intensifying research in less studied areas like Antarctica, South America and elsewhere.[21]

Links in the column "Continent" will give a list of craters for that continent.
