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]
The Eltanin impact has been confirmed (via an iridium anomaly and meteoritic material from ocean cores) but, as it fell into the Pacific Ocean, apparently no crater was formed. The age of Silverpit and the confirmed Boltysh crater (65.17 ± 0.64 Ma), as well as their latitude , has led to the speculative hypothesis that there may have been ...
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 Holocene Impact Working Group has suggested that multiple significant impact events occurred in the past 10,000 years, but astrononomical models indicate that impact events large enough to cause "hazardous tsunamis" should be expected only about once per 100,000 years, making the Working Group's claims improbable enough that they call for ...
New research has the answer. By studying the composition of meteorites that have landed over the years and the asteroids populating our solar system, astronomers have determined that about 70% of ...
In 2021, evidence for a probable impact 3.46 billion-years ago at Pilbara Craton has been found in the form of a 150 kilometres (93 mi) crater created by the impact of a 10 kilometres (6.2 mi) asteroid (named "The Apex Asteroid") into the sea at a depth of 2.5 kilometres (1.6 mi) (near the site of Marble Bar, Western Australia). [55]
The evidence of the impact included chemical signatures of the meteorite, small spherical structures formed from rock melted by the impact, and chunks of seabed mixed with other debris churned up ...
