Some scholars have argued that an impact event in an ocean or sea may create a megatsunami, which can cause destruction both at sea and on land along the coast, [42] but this is disputed. [43] The Eltanin impact into the Pacific Ocean 2.5 Mya is thought to involve an object about 1 to 4 kilometres (0.62 to 2.49 mi) across but remains craterless.
An asteroid that crashed into the Earth’s atmosphere over the UK and France was spotted just hours before it crashed. The world was given only seven hours warning that it was being approached by ...
The possible impact site is located at the edge of the Bellingshausen Sea (part of the Southern Ocean). The Eltanin impact is thought to be an asteroid impact in the eastern part of the South Pacific Ocean that occurred around the Pliocene-Pleistocene boundary approximately 2.51 ± 0.07 million years ago.

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) Rio Cuarto crater in Argentina. [2]
There are several lists of meteorite impacts of various types available: Category:Lists of impact craters contains lists on various planets, including Earth by continent; Meteorite falls are observed; Meteorite finds are rocks found on the ground which are geologically identified as meteorites; Meteorite contains lists of the most notable of ...
According to the university, Herd went to the crash site and measured a 2-square-centimeter (less than a square inch) divot in the walkway that was formed by the meteorite’s impact.
The meteorite struck Earth when it was still in its early years, a water world with only a few continents sticking out of the sea. In their fieldwork, Drabon said, they were looking for spherule ...
It is believed that the Zhamanshin crater is the site of the most recent meteorite impact event of the magnitude that could have produced a disruption comparable to that of a nuclear winter, but it was not sufficiently large enough to have caused a mass extinction. [2]
