District Profile

Dibrugarh is an important town of Assam, along with Guwahati, Jorhat and Silchar and is one of the more affluent districts of Assam. It is the second largest and fastest growing urban centre of Assam after Guwahati in terms of economic and infrastructural growth. Most of its economic activities are dominated by four major industries— Oil and natural gas, Tea production, Tourism & Fertilizer. It is said that Dibrugarh owes its name from the compound of two words. The word ‘Dibru’ or ‘Dibaru’ and ‘Garh’ (fort). Dibru or Dibaru is a stream that used to flow to the south of present Dibrugarh Town. When the British set up their militay base in this area, they constructed a Fort on the bank of Dibaru. Hence the name Dibrugarh was coined.

Vulnerability Analysis

Dibrugarh falls under Seismic Zone V and witnessed two major earthquakes in the region. The Assam-Tibet Earthquake of 1950 measuring 8.5 in the Richter scale was the worst felt earthquake in the district and nearly 4000 people lost their life in the State. With increased density of urban population over the period combined with haphazard growth the risk from earthquake has increased manifold.

The Brahmaputra has been the main determinant of flood in the district of Dibrugarh. Increase of the water level of mighty Brahmaputra along with its sub-tributary Buridihing leads to inundation of the catchment areas and causes flood. It causes a back flow of the water of its tributaries causing flood. This is the main reason of flood in the villages of the Chabua, Dibrugarh East, Dibrugarh West, Tengakhat & Moran Revenue Circle of the District. This type of back flow causes flood in places like Madhupur forest village area, Kolakhowa area, Garudhoria area under Dibrugarh West Revenue Circle. The Dibrugarh city also experience recurrent urban flooding and water logging in its main hub areas are common during monsoon and inundated frequently due to excessive rainfall and flooding by the River Brahmaputra.

Presence of major industries like the Asia’s first oil refinery-Digboi, head quarter of Oil India Ltd., Namrup Fertilizer industry and upcoming Brahmaputra Cracker Polymer Limited are situated either in Dibrugarh or its nearby districts. Moreover, the entire district has many oil and natural gas rigs owned by the Oil India Limited and Oil and Natural Gas Commission making the whole district prone to chemical & industrial disaster as well.

Besides natural & industrial hazards, the city is also vulnerable to human induced hazards like fires, accidents etc. While fire accident occurs due to urban localities and thatched roof houses, road mishaps are frequently occurred due to reckless driving and poor road conditions.
