The state saw rapid industrialization and growth in tourism in subsequent years. Topography Kutch District, at , is the largest district in India. The administrative headquarters is the city of Bhuj which is geographically in the center of the district. Gandhidham is the largest city and Financial centre of Kutch. Other main towns are Rapar, Nakhatrana, Anjar, Mandvi, Madhapar, Mundra and Bhachau. Kutch has 969 villages. Kala Dungar (Black Hill) is the highest point in Kutch at . Kutch is virtually an island, as it is surrounded by the Arabian Sea in the west; the Gulf of Kutch in south and southeast and Rann of Kutch in north and northeast. The border with Pakistan lies along the northern edge of the Rann of Kutch, of the Sir Creek. The Kutch peninsula is an example of active fold and thrust tectonism. In Central Kutch 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 Kutch mainland fault and the epicentre of the earthquake of 2001 lying at the eastern extreme of Kutch mainland fault, it is suggested that the eastern part of the Kutch 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 Kutch mainland hill range (viz. Jawaharnagar, Khirsara, Devisar, Amarsar and Bandhdi) were completely erased during the 2001 earthquake. Rivers and dams There are ninety-seven small rivers in Kutch District, most of which flow into the Arabian Sea, but some of which feed the Rann of Kutch. Twenty major dams, and numerous smaller dams, capture the rainy season runoff. While most of these dams do not affect the Ranns, as they are on rivers that feed directly into the Arabian Sea, storage of rainy season water upstream from Kutch and its use in irrigation has resulted in less fresh water coming into the Ranns of Kutch during the rainy season. This is true of the Great Rann, but particularly true of the Little Rann which is fed by the Luni, Rupen, the Bambhan, the Malwan, the Kankawati, and the Saraswati rivers. However
