Indira Point
Explanation
The 2004 Indian Ocean Tsunami was triggered by a massive undersea megathrust earthquake off the coast of Sumatra. This seismic event caused vertical displacement of the ocean floor and significant tectonic subsidence in the Andaman and Nicobar archipelago, altering the coastal geography.Analysis of Options:
- Indira Point: Located on the southern tip of Great Nicobar Island, Indira Point was the southernmost point of the Indian Union. Due to the tectonic activity associated with the 2004 earthquake, the land in this region subsided, leading to the submergence of Indira Point under the sea.
- Port Blair: Located in South Andaman, it is the administrative capital. While it experienced tremors and tsunami waves, the location remains above sea level.
- Saddle Peak: Located in North Andaman, this is the highest peak of the archipelago (approximately 732 meters). It was not submerged.
- Car Nicobar: This is the headquarters of the Nicobar district. While it faced catastrophic devastation, the island itself was not completely submerged.
Key Takeaway: The 2004 Tsunami caused the tectonic subsidence of the Great Nicobar Island, resulting in the submergence of Indira Point, India's southernmost territory.
