What happens if a meteorite falls into the Indian Ocean?

In fact, the consequences directly depend on the size of the meteorite.
If its surface area exceeds 1 square kilometer, the consequences are fraught with significant flooding of the surface of India and Asia, on whose territory about 35-40% of the world’s population now lives.
As a result of the resulting tsunami, there will be a complete flooding of the modern territories of the islands of Oceania, the east coast of Africa and the west coast of Australia.
This exodus will lead to a planetary catastrophe and a significant reduction in the population of our planet.
