Eltanin impact
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. The impact occurred at the north edge of the Bellingshausen Sea 1,500 km (950 mi) southwest of Chile, where the sea floor is approximately 4–5 kilometres (2.5–3.1 mi) deep. The asteroid was estimated to be about 1 to 4 km (0.6 to 2.5 mi) in diameter. No crater associated with the impact has been discovered. The impact likely evaporated 150 km3 (36 cu mi) of water, generating large tsunami waves hundreds of metres high.
