Andaman and Nicobar Islands
Andaman and Nicobar Islands History
On 26 December 2004 the coasts of the Andaman and Nicobar Islands were devastated by a 10 metre high tsunami following the 2004 Indian Ocean earthquake. At least 7,000 people (possibly a conservative estimate) were believed to have been killed on the Nicobar and Andaman Islands during the disaster.
While newer settlers of the islands suffered the greatest casualties from the tsunami, most of the aboriginal people survived because oral traditions passed down from generations ago warned them to evacuate from large waves that follow large earthquakes. 
Andaman and Nicobar Islands Geography
There are over 570 islands in the territory, of which only some 38 are permanently inhabited. Most of the islands (about 550) are in the Andamans group, 26 of which are inhabited. The smaller Nicobars are comprised of some 22 main islands (12 inhabited). The Andmans and Nicobars are separated by a channel (the Ten Degree Channel) some 150 km wide.
The total area of the Andaman Islands is some 6,408 km2; that of the Nicobar Islands approximately 1,841 km2.
Andaman and Nicobar Islands Administration
As a Union Territory, the Andaman and Nicobar Islands is nominally under the direct control of the Indian Head of State. In practice, a Lt. Governor is appointed to directly administer the territory.
The territory is divided into two districts for administrative purposes. These are the Andaman district and Nicobar district, responsible for their respective island groups. Each district is headed by a Deputy Commissioner, in charge of the various local administrative service departments, assisted by several Assistant Commissioners and sundry other posts. the districts also have Indian Administrative Service-appointed post of district collector, responsible for overseeing revenue collection and some other related services. In both cases, this post forms part of the Deputy Commissioners' portfolios, rather than being held by a separate individual.
In turn, these two districts are further sub-divided into administrative entities known locally as tehsils, which are roughly equivalent to local councils or counties. The tehsils are also grouped into local Sub-Divisions, another administrative level which primarily serves as a basis for the combining of local resources. In the case of the Nicobars, the Sub-Divisions and the tehsils are effectively one and the same.
