The impact of asteroid Cixolov, which killed the dinosaurs 66 million years ago, produced a tsunami that spread throughout the world, according to the first global similarity of the event.
Scientists led by Molly Range of the University of Michigan Ann Arbor used both models for their simulation. One for the initial effect of a 14 km diameter asteroid in shallow water and another for the expansion of water that disappeared along the ancient ocean.
According to the simulation, the first effect of the asteroid effect was a tsunami wave at a height of about 1,500 meters. The study was presented at the fall meeting of the American Geophysical Association.
The impact of the tsunami spread rapidly from the Gulf of Mexico to the Atlantic Ocean and through the sea routes of Central America to the Pacific in the first 24 hours. The reflection and reflection of the waves create a more complex tsunami pattern 48 hours after impact, with heights of 14 meters. The abnormal flow velocity 20 cm per second along the coasts around the world could have altered precipitation more than 6,000 km from the source of impact.
Compared to the Indian Ocean tsunami of December 26, 2004, one of the biggest tsunamis in modern records, the Tsunami of impact was about 2,600 times more energetic.
This model shows that the impact of the asteroid not only had significant effects on the global atmosphere and biosphere, but also created a tsunami of such magnitude that its impact was felt in much of the world ocean.
