As the trend in the Earth Impact Database for about 26 confirmed craters younger than a million years old shows that almost all are less than two km (1.2 mi) in diameter (except the three km (1.9 mi) Agoudal and four km (2.5 mi) Rio Cuarto), the suggestion that two large craters, Mahuika (20 km (12 mi)) and Burckle (30 km (19 mi)), formed only ...
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] The source of the enormous Australasian strewnfield (c. 780 ka) is a currently undiscovered crater probably located in Southeast Asia. [12] [13]
Naonobu is a small lunar impact crater named after Japanese mathematician Ajima Naonobu. It is located on the eastern Mare Fecunditatis, to the northwest of the prominent crater Langrenus, and it forms a triple-crater formation with the adjacent Atwood to the south and Bilharz just to the southwest. Naonobu and Atwood are separated by only a ...
At Cap d’Erquy, along the northern coast of France, the satellite system picked up on potential structures buried into a crater, according to the release, and the researchers took a closer look.
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation
Nawish is an impact crater on the dwarf planet Ceres. It is named after the Acoma guardian of the field. The name was officially approved by the International Astronomical Union (IAU) on 3 July 2015. [1] It is the namesake of the Nawish Quadrangle. [2] Nawish is medium in size, at roughly 77 kilometres (48 miles) in diameter. [1]
[20]: 24 Black Point, today on the north shore of Mono Lake, is a flattened volcanic cone of basaltic debris that formed under the surface of a much deeper Mono Lake about 13,300 years ago, during the most-recent glacial period. [22]: 53 Several eruptive episodes from 1,600 to 270 years before present in Mono Lake formed Negit Island.
The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed. [ 2 ] [ 3 ] The remaining structure, comprising the deformed underlying bedrock, is located in present-day Free State province of South Africa .
