 | The eruption of Santa Maria volcano in 1902 was one of the largest eruptions of the 20th century, forming a large crater on the mountain’s southwest flank. Since 1922, a lava-dome complex, Santiaguito, has been forming in the 1902 crater. Growth of the dome has produced pyroclastic flows as recently as the 2001—they can be identified in this image. The city of Quezaltenango (approximately 90,00... |  | 10/27/2005 | 384 |

 | Darwin Crater was discovered in 1972 by Ramsay J. Ford. The crater lies 26 km south of Queenstown Tasmania.
The crater was formed by a 20 - 50 m diameter asteroid that struck the Earth approximately 730,000 +/- 40,000 years ago.
The crater has a diameter of 1.2km and is 230 metres deep. It was a lake until about 30 000 years ago, today it is filled with sediment. The crater is ass... |  | 05/28/2006 | 964 |

 | The Silverpit crater in the North Sea was discovered in 2002 during a seismic oil exploration .
The crater is about 2.4 km wide and surrounded by a set of concentric rings, which extend to about 10 km away from its centre.
Its age is thought to be about 65 million years old, roughly coincident with the formation of the Chicxulub Crater.
The crater currently lies below a ... |  | 12/09/2005 | 1,056 |

 | Forty kilometers north of Pretoria lies a ring of hills a kilometer in diameter and 100 meters high. These hills are the walls of an impact crater left by an asteroid which hit there some 200 000 years ago. The Tswaing crater is similar in size to the well-known Barringer meteor crater in Arizona. The crater walls at Tswaing were originally about twice as high as they are today. |  | 07/13/2005 | 965 |

 | Mahuika crater is a submarine bolide impact crater, 20±2 kilometres wide and over 153 meters deep, on the New Zealand continental shelf, named for the Maori god of fire.
Researchers have found evidence from an Ice Core indicating that the large Impact occurred circa 1443 A.D.
Samples taken from the West Antarctic Siple Dome ice core that date between 1440 and 1448 A.D. show high ... |  | 01/28/2006 | 877 |

 | This a recently found large crater in Antarctica, that was created by a 50 kilometres wide space rock 250 million years ago, and contributed to, or caused the Permian-Triassic extinction, the greatest mass extinction on Earth.
The crater is about 500 kilometres wide, and is now buried beneath 1 kilometre of ice. It was found by looking at differences in density that show up in gravity me... |  | 06/02/2006 | 1,978 |

 | Dome A or Dome Argus is an Antarctic plateau located 1200 kilometres inland. It is thought to be one of the coldest naturally occurring places on Earth, with temperatures believed to reach -90 °C. It is the highest ice feature in Antarctica, comprising a dome or eminence of just over 4,000 m elevation, located near the centre of East Antarctica and approximately midway between the head of Lambe... |  | 01/13/2006 | 704 |
