Georesource Potential and Geohazard Status of the Bay of Bengal vis-à-vis Sustainable Development of ‘Blue Economy
Author: Aftab Alam KhanDOI: doi.org/10.70279/bmj-v3-i1-1087
Formation of the Bay of Bengal is linked to the opening of the Indian Ocean and covers an entire off-shore region of Bangladesh wherein the geological processes and tectonic activities in the Bengal Basin have greatly influenced in enriching the Bay of Bengal. Spreading and creation of new seafloor of the Bay of Bengal have continued with the Indian plate motion to the north and northeast. Hence, the Bay of Bengal has been enriched with georesources. ‘Blue Economy’ is a concept that can significantly contribute to the socio-economic development of the nations situated around the oceans and seas. However, the sustainability of ‘Blue Economy’ greatly depends on the proper assessment and utilisation of the marine georesources. It is equally important to evaluate the geological hazards of the seas and oceans around the coastal countries in order to better safeguard the development of ‘Blue Economy’. Although Bangladesh is situated along the coast of northern Bay of Bengal having the largest continental shelf and the longest deep-sea fan within its legal exclusive economic zone (EEZ), it is the least studied and explored bay in the region that demands much greater attention. The present study is an effort to focus on to the possible geological resources like oil, gas and mineral potentials of the Bay of Bengal within EEZ of Bangladesh. Geological hazards like earthquake, tsunami and other ocean-related geological hazards have also been identified and their probable impact has been assessed for proper planning of development of a sustainable ‘Blue Economy’.
