[Note Guidelines] Photographer's Note
The aerial photograph shows the southern tip of Ross Island at Port Blair. If you look at the color of the water, it is merky close to the shore; possibly due to the plate tectonic tilt it suffered during earthquake that generated the great Indian Ocean tsunami of 2004.

The few degrees tilt towards East (the photograph is facing East) has exposed the proportion of the top soil of the island which gets washed out during every hightide phase.

Assessments done by Dr. Roger Bilham of the University of Colorado indicate that the northern parts of the Andaman group of islands experienced a permanent average uplift of four to six feet (1.2 metres to 1.8 metres) while most parts of the Nicobars went significantly under - four feet in Car Nicobar and a staggering 15 feet (4.57 m) at the southernmost tip - Indira Point on Great Nicobar Island. The pivot of this swing experienced by the islands can be calculated to be roughly located south of Port Blair.

Hi Subhash,

An excellent shot showing us the damage from the earthquake. Your notes, as always, are most informative. The southern tip of Ross Island looks so lush with the beautiful green trees. The boats behind the island add to the fine composition.


Hi Subhash

Very interesting picture and notes. I do hope the islands are allowed to restore some biological equilibrium and the authorities prevent mindless development that can intrude with the slow process.


Geologically speaking this is a rare image Dr. I do remember some of what you say in your notes, but to see it clearly from the air gives a whole new meaning...As a person interested in geology, I always appreciate the more unusual viewpoint which you have done so well here1
