The Kachchh district, with 45,652 km², is one of the largest districts(Ladakh is the largest) in India. The administrative headquarters is in Bhuj which is geographically in the center of district. Other main towns are Gandhidham, Rapar, Nakhatrana, Anjar, Mandvi, Madhapar and Mundra. The district has 966 villages.
Kachchh is virtually an island, as it is surrounded by the Arabian Sea in the west; the Gulf of Kachchh in south and southeast and Rann of Kachchh in north and northeast. The border with Pakistan lies along the northern edge of the Rann of Kachchh, of the disputed Kori Creek. The Kachchh peninsula is an example of active fold and thrust tectonism. In Central Kachchh there are four major east-west hill ranges characterized by fault propagation folds with steeply dipping northern limbs and gently dipping southern limbs. From the gradual increasing dimension of the linear chain of hillocks towards the west along the Kachchh mainland fault and the epicentre of the earthquake of 2001 lying at the eastern extreme of Kachchh mainland fault, it is suggested that the eastern part of the Kachchh mainland fault is progressively emerging upward. It can be suggested from the absence of distinct surface rupture both during the 1956 Anjar earthquake and 2001 Bhuj earthquake, that movements have taken place along a blind thrust. Villages situated on the blind thrust in the eastern part of the Kachchh mainland hill range (viz. Jawaharnagar, Khirsara, Devisar, Amarsar and Bandhdi) were completely erased during the 2001 earthquake.[2]
