Geography of Kolkata
Kolkata is located in the eastern part of India. It has spread linearly along the banks of the Hooghly River. The Kolkata Municipal Corporation has an area of 205 square kilometres.[1] The city is near sea level, with the average elevation being 17 feet.[2] The whole area is in the Ganges Delta which starts within 100 km south of the city. Most of the city was originally marshy wetlands, remnants of which can still be found especially towards the eastern parts of the city.
Geology
Indo-Gangetic Plain, the soil and water are predominantly alluvial in origin. Kolkata is located over the "Bengal basin", a pericratonic tertiary basin.[3] Bengal basin comprises three structural units: shelf or platform in the west; central hinge or shelf/slope break; and deep basinal part in the east and southeast. Kolkata is located atop the western part of the hinge zone which is about 25 km (16 mi) wide at a depth of about 45,000 m (148,000 ft) below the surface.[3] The shelf and hinge zones have many faults, among them some are active. The total thickness of sediment below the Kolkata is nearly 7,500 m (24,600 ft) above the crystalline basement; of these the top 350–450 m (1,150–1,480 ft) is quaternary, followed by 4,500–5,500 m (14,760–18,040 ft) of tertiary sediments, 500–700 m (1,640–2,300 ft) trap wash of cretaceous trap and 600–800 m (1,970–2,620 ft) permian-carboniferous Gondwana rocks.[3] The quaternary sediments consist of clay, silt, and several grades of sand and gravel. These sediments are sandwiched between two clay beds: the lower one at a depth of 250–650 m (820–2,130 ft); the upper one 10–40 m (30–130 ft) in thickness.[4] According to the Bureau of Indian Standards, on a scale ranging from I to V in order of increasing susceptibility to earthquakes, the city lies inside seismic zone III.[5]

Spread roughly north–south along the east bank of the Hooghly River, Kolkata sits within the lower Ganges Delta of eastern India; the city's elevation is 1.5–9 m (5–30 ft).[6] The city is fringed by extensive mangrove ecosystems and tidal flats.[7]

The Kolkata metropolitan area is spread over 1,886.67 km2 (728.45 sq mi)[8]: 7 and comprises 4 municipal corporations (Kolkata Municipal Corporation, Bidhannagar Municipal Corporation, Howrah Municipal Corporation and Chandernagore Municipal Corporation), 37 local municipalities (Bally Municipality is merged with Howrah Municipal Corporation and Rajarhat-Gopalpur Municipality is merged with Bidhannagar Municipal Corporation, so total number of municipalities becomes 37 from 39) and 24 panchayat samitis.
The urban agglomeration encompassed 72 cities and 527 towns and villages, as of 2006[update].[9] Suburban areas in the Kolkata metropolitan area incorporate parts of the following districts: Kolkata, North 24 Parganas, South 24 Parganas, Howrah, Hooghly and Nadia.[10]: 15 Kolkata, which is under the jurisdiction of the Kolkata Municipal Corporation (KMC), has an area of 205 km2 (79 sq mi).[11] The east–west dimension of the city is comparatively narrow, stretching from the Hooghly River in the west to roughly the Eastern Metropolitan Bypass in the east—a span of 9–10 km (5.6–6.2 mi).[12] The north–south distance is greater, and its axis is used to section the city into North, Central and South Kolkata. East Kolkata is also a section.
