The Indian Ocean is the third-largest of the world's five oceanic divisions, covering 70,560,000 km 2 (27,240,000 sq mi) or approximately 20% of the water area of Earth's surface. [4] It is bounded by Asia to the north, Africa to the west and Australia to the east.
Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous, and they can affect entire ocean basins. The 2004 Indian Ocean tsunami was among the deadliest natural disasters in human history, with at least 230,000 people killed or missing in 14 countries bordering the Indian Ocean.

The Indian Ocean Geoid Low (IOGL) is a gravity anomaly in the Indian Ocean. A circular region in the Earth's geoid, situated just south of the Indian peninsula, it is the Earth's largest gravity anomaly. [1] [2] It forms a depression in the sea level covering an area of about 3 million km 2 (1.2 million sq mi), almost the size of India itself.

Meanwhile, the annual precipitation totals have shown a gradual decline, due to a weakening monsoon circulation [6] as a result of the rapid warming in the Indian Ocean [7] and a reduced land-sea temperature difference. This means that there are more extreme rainfall events intermittent with longer dry spells over central India in the recent ...
